Part Number: 40860
Material: Bronze (Check Valve)
Body Thread Size/Type: 1/2-14 NPT Female
Weight (lbs): 2
Part Description: Check valves are used in main/reserve and selector valve systems. On main/reserve systems, the check valve prevents pressurization of the reserve system manifold by blocking the flow of INERGEN® agent from the main system to the reserve system. The check valve allows gas flow from the reserve (if actuated) to pass through into the distribution piping. On selector valve systems, check valves separate the actuation of smaller system(s) from the largest ones.

Part Number: 43168
Material: Steel (Pull Equalizer, Long)
Thread Size/Type: 3/8 in. NPT Female
Weight (lbs): 4
Part Description: The remote cable pull equalizer, Part No. 43168 is 20 3/4 in. (52.7 cm) is used in systems where manual actuation of the cylinder valve and operation of a selector valve must be accomplished at the same time. The pull equalizer is mounted in the remote pull station cable line. By pulling the remote pull box, the cable attached to the pull equalizer will pull the internal cable clamp in the pull equalizer which in turn will pull the cables attached to the cylinder valve and selector valve, causing them to operate. Note: Only the longest equalizer, Part No. 43168, can be used for valves utilizing sectors.

Part Number: 42791
Material: Steel (Pull Equalizer, Short)
Thread Size/Type: 3/8 in. NPT Female
Weight (lbs): 7
Part Description: The remote cable pull equalizer, Part No. 42791 is 13 3/4 in. (34.9 cm) long is used in systems where manual actuation of the cylinder valve and operation of a selector valve must be accomplished at the same time. The pull equalizer is mounted in the remote pull station cable line. By pulling the remote pull box, the cable attached to the pull equalizer will pull the internal cable clamp in the pull equalizer which in turn will pull the cables attached to the cylinder valve and selector valve, causing them to operate.

Part Number: 45515
Material: Brass (Body), Brass (Wheel)
Thread Size/Type: 3/8 in. NPT
Weight (lbs): 1
Part Description: The corner pulley is required on an INERGEN® system whenever a mechanical release pull cable run involves a change in direction. Corner pulleys are installed as part of the cable housing (pipe or conduit) and provide 90° direction changes with minimal force loss and no induced kinking. This type of corner pulley is made of forged brass and is threaded for 3/8 in. NPT pipe. The brass wheel corner pulley is designed for location inside or outside the protected space.

Part Number: 42678
Material: Brass (Body), Nylon (Wheel)
Thread Size/Type: 3/8 in. NPT
Weight (lbs): 1
Part Description: The corner pulley is required on an INERGEN® system whenever a mechanical release pull cable run involves a change in direction. Corner pulleys are installed as part of the cable housing (pipe or conduit) and provide 90° direction changes with minimal force loss and no induced kinking. This type of corner pulley is made of forged brass and is threaded for 3/8 in. NPT pipe. The nylon wheel corner pulley is designed for location only outside the hazard space.

Part Number: 423250
Material: Aluminium (Body), Stainless Steel (Roller)
Thread Size/Type: 1/2 in. (Use with EMT)
Weight (lbs): 0.3
Part Description: The corner pulley is required on an INERGEN® system whenever a mechanical release pull cable run involves a change in direction. Corner pulleys are installed as part of the cable housing (pipe or conduit) and provide 90° direction changes with minimal force loss and no induced kinking. This type is made of die cast aluminum, has a ball bearing roller, and uses compression fittings for 1/2 in. EMT connections.

Part Number: 42113
Material: Stainless Steel (Cable), Brass (Swaged Fitting)
Weight (lbs): 1.5
Part Description: The 1/16 in. diameter cable is used to attach remote manual pull boxes to cylinder valves, pull equalizers and control boxes. The cable is constructed of stranded, stainless steel wire. The cable is available in lengths of 50, 100, and 150 ft (15.2, 30.5, and 45.7 m). The cable assemblies include a brass swaged end fitting for attaching to the remote pull box.
