Gadren Machine Co., a division of Control Devices LLC

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 world’s 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.

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.

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: 250ºF

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 90º 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.

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.
