The patented Econo Check check valve is designed for non-oil lubricated compressors for 5 HP and under. The compact valve design has proven to be a robust economical check valve that has sold over 8 million units in the past 10 years.

Construction: One-piece brass or plated steel body with a stainless steel spring, Fluorocarbon poppet and high temperature engineered thermoplastic internal guides.

A variety of high-pressure cylinder valves used for specialty cylinder applications are available. Standard C10 valves are available, as well as custom designs for almost any application. Designs are available in brass or aluminum, depending on the gas composition and pressure. Features include thermal and pressure relief devices built into the valve.


Construction: Brass (electrolysis nickel-plated), aluminum, fluorocarbon seals and stainless steel springs
Options: Rupture Disc for over-pressure protection; fusible metal for over temperature pattern

Control Devices works with some of the worlds leading OEMs in the design and manufacture of specialized valves and nozzles for use in gas-based fire suppression systems. Please contact us for more information on our capabilities in this sector.

Model SP ASME safety valves are designed for applications where a compact size is required for high flow capacities. For example, a 3-HP compressor may add 10 SCFM of air into the receiver at 125 psi. The SP will flow 42 SCFM at 125 psi set pressure, so it will be adequate for this system. Resilient fluorocarbon rubber pad ensures valve is bubble-tight to within 10% of set pressure. The valve is stamped with UV and NB symbols. Set pressure tolerance is +-3%.

Construction: All brass with stainless steel springs
Max. Temperature: 250F

Model ACM carry tank manifold feature a built-in shutoff valve and a non-code safety valve set to customer specifications. A pressure switch mount and tank pressure gauge port allow all control and outlet functions to be connected to a 12" NPT tank port. Flow capacity of outlet valve and safety valve make this manifold suitable for compressors of 3 HP or smaller.

TC12 throttle controls are used with gas engine-driven compressors to reduce the engine speed to idle when the continuous run control (such as Model LGM20, LGM30 and LGM40 vent unloaders or P25 pilot valve) has reached its cut-out setting. This saves fuel, reduces noise, as well as reduces engine and compressor wear.

The 18 NPT inlet of the TC12 is connected to the throttle control port of the vent un-loader or connected into a 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.

During operation, the vent unloader or pilot valve sends a pressure signal to the TC12 at the cut-out setting, causing the TC12 piston to extend the control cable which pushes the throttle lever, forcing the engine to idle down. At the cut-in 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.

Model LGM40 Mark IV Load Genie continues in the tradition of the original LGM20 Mark II Load Genie & LGM30 Mark III Load Genie.

Model LGM40 is a vent unloader, therefore built-in head unloaders are not required on the compressor. This valve combines all of the components required for a continuous run compressor application: a pilot valve, a vent valve and a check valve.

The compact size and the combination of straight-through 90 flow design of the LGM40 makes installation simple. Install the valve into the air receiver and attach the compressor discharge line to the valve inlet. This valve is suitable for compressors of up to 30 SCFM delivery.

Models CTM & CTMD are used when assembling air compressor systems and portable air tanks. The air manifold design incorporates a tank filler valve into the built-in shutoff valve. The filler valve mates to a typical tire chuck for easy tank pressurization. The integral non-code safety valve is factory pre-set at 150 psi. Included with the air manifolds is a tank pressure gauge.

The TC63 pneumatic throttle control valve is used with gas engine-driven compressors to reduce engine speed to idle when the continuous run control (such as Models LGM20, LGM30 & LGM40 vent unloaders or Model P25 pilot valve) has reached its cut-out setting. This saves fuel and reduces engine and compressor wear.

The TC63 is connected to the throttle control port of the vent unloader via an air line. The air line can also be connected to a tee of the head unloader line for pilot valve installation. The linkage is attached to the throttle lever on the engine.

During operation, the vent unloader pilot valve sends a pressure signal to the pneumatic throttle control piston to extend, pushing the throttle lever on the engine to its idle position. At the cut-in setting, the pressure signal that is applied to the pneumatic throttle control is vented by the vent unloader or pilot valve, allowing the spring to return to the piston and engine throttle lever to the original, full speed, position.

The TC63 pneumatic throttle control valve is available in 58 and the operational 516.

The "P25" pilot valve is an industry standard. Valve cut-incut-out pressures are factory set per customer specifications. If specifications are not provided, the valve is set at standard setting of 95-115 psi, or valve can be field adjustable. Valve includes mounting boss, tapped with a 38-16 UNC thread, a 14 NPT inlet and a 18 NPT outlet; comes standard with unloading sleeve for gas engine warm up. Maximum cut-out pressure is 250 psi.
