ASME Safety Valves Datasheet

Model "SP" ASME safety valves are designed for applications where a compact size is required, and high flow capacities are needed. For example, a 3 HP compressor may add 10 SCFM of air into the reciever at 125 psi. The "SP" will flow 42 SCFM at 125 psi set pressure, so it will be adequate for this system. Resilient silicone rubber pad insures valve is bubble-tight to within 10% of set pressure. ¼ BSPT inlets.

All brass construction with 17-7 PH stainless steel spring. Stamped with "UV" and "NB" symbols. Available set pressure range 75 psi to 250 psi. Set pressure tolerance ± 3% of set pressure. 250°F max. temperature.

These valves are in applications ranging from garden-type pump sprayers to air brake compressor heads. Non-code valves may be used wherever the component being protected is not an ASME pressure vessel. Non-code valves offer some economy over the ASME coded valves, but do not necessarily have the set pressure accuracy or certified flow capacity of their ASME brethren.

The Super-Chek® design has been proven over the last 15 years to be the standard for air compressor in-tank check valves. One-piece brass bodies, stainless steel springs, and glass-filled fluoropolymer poppets all add to long term reliability, while the eight discharge holes insure quiet operation. Valves are 100% tested for backflow leakage performance. 450 psi max pressure, 400° F max temperature.

In-Tank Check Valves Datasheet

The "B2" design of in-tank check valves are specifically designed for OEM use. These valves offer outstanding performance at a great price! Valve bodies are all brass with stainless steel springs and glass-filled fluoropolymer poppet. High flows are insured with oversize discharge holes. Final assembly is an operation, which insures long life, but does not allow disassembly. 450 psi max pressure, 400°F max. temperature.

Please note that the "barrel" length of the "B2" valve is shorter than our Super-Chek® line, so the OEM must insure that any "skirt" on the tank fitting is clear of the valve discharge holes (see diagram above). Otherwise, potentially bammaged backpressure may build up in the compressor discharge line and compressor head.

Our piston check valves offer bubble-tight sealing capabilities at low pressure drops. They can be used as the valves for small compressors, or as components in pneumatic circuits. Valve bodies and pistons are brass with fluorocarbon O-rings and stainless steel springs. 250 psi max pressure, 250°F max temperature. Available inlet/outlet configurations and orifice size.

In-Line Check Valves Datasheet

A compressor running in a "start-stop" mode operates more efficiently if the pressure trapped in the compressor head and discharge line is released after each pump-up cycle. This allows smoother starts and the use of a motor with lower starting torque. The most convenient way to release this trapped pressure is to use Load Genie® combination check and unloader valve. Simply install this unique valve in the compressor discharge line, and the Load Genie® does the rest! The Load Genie® senses air flow when the compressor is running and closes an unloading orifice port. When airflow stops (such as when the pressure switch turns off the motor), the Load Genie® opens the unloading orifice to release head pressure, and a built-in check valve keeps receiver air from leaking back into the discharge line and compressor head.

Alternative methods rely on external unloading valves mounted on the pressure switch or compressor. These external unloading valves are connected with appropriate tubing and fittings to the compressor discharge line or compressor head. A tank check valve is also required. These systems, then, consist of the unloading valve, connecting tubing with appropriate fittings, a tank check valve, and the labour to install it all. Compare this to the single component installation of a Load Genie®, and the advantages are apparent.

Unloading Check Valves Datasheet

• It is most important to match the rated flow of the Load Genie® with the compressor flow capacity. Also, keep in mind that as the compressor discharge pressure goes up, the flow capacity goes down. If the flow capacity of the compressor drops below the minimum rated flow of the Load Genie®, the valve will react as if the compressor had stopped, and will vent the discharge line. Therefore, it is better to size the Load Genie® toward the maximum end of its rated flow range.
• Next, select the desired inlet configuration, tubing compression fitting or internal thread. Please note that, based on the flow selection criteria above, inlet and outlet sizes may not match the fitting sizes found in the compressor and tank. In this case, use appropriate reducers available in any hardware store.
• Vibra-Seal® 516 is available as an option on external NPT threads.

Mark III Load Genie®

The Mark III Load Genie® is a self-contained unloading valve and can be used wherever a continuous run compressor is required. The compressor may need to run continuously because the air demand is close to the maximum output of the compressor, or because the compressor is driven by a gasoline or diesel engine.

Since the Mark III is a "vent" unloader, no built-in head unloaders are required on the compressor. The Mark III contains all components required; the pilot valve, the vent valve and check valve. Simply install the Mark III in the discharge line between the compressor and the reciever. Valve cut-in and cut-out pressures factory set per customer specifications. Minimum cut-out pressure is 60 psi and maximum cut-out pressure is 250 psi. If no settings are specified, the valve is set at our standard setting of 115 psi cut-out and 95 psi cut-in. The valve is also field adjustable. The Mark III is suitable for compressors of up to 30 SCFM. Details of construction include forged brass body, brass and zinc-plated steel internal components, stainless steel springs, and glass-filled fluoropolymer poppets. Options include an 1/8 NPT tapped port for throttle control of a piston engine, a lockout clip for "dual control" applications, a especial 1/8 NPT tapped port for a pressure switch unloader valve and a toggle unloading lever for one-hand warm up control. Vent port muffler is standard.

Continuous Run Unloaders Datasheet

TC12 throttle controls are used on piston engine-driven compressors to reduce engine speed to idle when the continuous run control (such as CDI model LGM20 and LGM30 vent unloaders or model P25 pilot) has reached its "cut-out" setting. This saves fuel and reduces engine and compressor wear.

The 1/8 NPT inlet of the TC12 is connected to the throttle control port of the vent unloader or connected into the "tee" of the head unloader line of pilot valve installations. The cable end is attached to the appropriate throttle linkage on the engine and the cable housing is appropriately anchored using the supplied cable clamps.

In operation, the vent unloader or pilot valve sends a pressure signal to the TC12 at the cut-out setting. This causes the TC12 piston to extend the control cable which pushes the throttle lever, causing the engine to idle down. At the cut-out setting, the pressure signal going to the TC12 is vented, allowing the spring to return the piston, cable and throttle lever to the original full speed position.

The P25 unloader is an industry standard. Details of construction include a precision machined, forged brass body, brass adjustment screws, and stainless steel ball spring.

Valve cut-in and cut-out pressures are factory set per customer specifications (if no specifications are given, valve is set at standards settings of 95-115 psi). Valve is also field adjustable.

Valve includes a mounting boss, tapped with a 3/8-16 UNC thread, a ¼ NPT inlet and a 1/8 NPT outlet. Valve comes standard with unloading sleeve for piston engine warm up. Options include a toggle for one-hand unloading, a lock-out thumbscrew for dual control systems, and a ¼ NPT nipple installed into the inlet port. Maximum cut-out pressure 250 psi, minimum cut-out pressure 60 psi. Maximum temperature 350°F.

Pilot Valves Datasheet

Manifolds from Control Devices mean savings and convenience when assembling air compressor systems and portable air tanks. Both models feature solid brass bodies and components, zinc-plated or stainless steel prongs, nitrile O-rings, and silicone rubber safety valve seals.

Accessories Datasheet

The M20053 muffler is available as an option on the LGM20 and LGM30 unloader valve, but is also great for other applications that require a silencer with high flow capacities. 3/8 NPT inlet, 1-1/8" long. Brass body with aluminium diffuser screen.

CS12 and CS25 valves bleed air from the compressor head during the first few pump revolutions, thus reducing motor starting torque requirements. These valves are especially helpful on oil-lubed pumps that may be subject to low temperatures and low starting voltages, such as a contractor unit that may sit outside overnight and be connected to a long extension cord.

The CS valve is installed into any convenient port upstream of the tank check valve. Typical installations are into a 1/8 NPT port in the check valve (CDI in-tank check valves are available with the CS12 installed as an option), into a port tapped in the head of the pump, or into a "tee" in the discharge line. With the discharge line at zero pressure, the CS valve is open. As the pump starts, air flows out the CS valve to atmosphere. As pump speed and discharge pressure increase, the valve snaps shut and stays closed until the end of the pump-up cycle. When the head is unloaded (a pressure switch unloader or similar device is required), the CS valve re-opens, and is ready for the next start up.

Body and piston are brass, with a stainless steel spring and fluorocarbon O-ring.

Model TRV thermal relief valves are typically installed into pressure washer systems where a specific maximum water temperature is desired. The valve remains closed at normal operating temperature, but opens as the temperature rises allowing the hot water to escape and cool water to recirculate through the system. Brass construction with nitrile seal. Available in 1/4, 3/8, and 1/2 NPT inlets. 140°F opening temperature.

Model ESV easy start valve is installed into a pressure washer system allowing water to bypass from the high pressure side of the pump back to the inlet until a specific pressure is reached. Brass construction, stainless steel ball, seat, and spring. 3/8 NPT inlet, available with 1/4 hose barb outlet or 1/8 NPT tapped port.

Drain All Condensate Traps are completely pneumatic and corrosion-resistant. Each trap is actuated only as necessary according to the needs of your system. This prevents over- and under-draining, preserving system pressure and eliminating wasted compressed air. The drains are "green" products and require no electricity, so energy costs are minimized. Because the drains are pneumatic, they are not affected by the vulnerabilities of electrical devices such as timer solenoid valves, motorized ball valves or electrically-operated float traps.
