The Betts CHR2L1SSTS Vapor-Pro Hydraulic Vapor Recovery Valve is a versatile, robust positive opening vapor valve that facilitates the transfer of displaced air and vapor during loading and unloading. Its 316L stainless steel construction and PTFE seals suit a wide variety of volatile organic compounds (VOCs) and chemicals transported in DOT 407 and 412 cargo tanks. This low-profile version accommodates tighter tank piping configurations. The swivel connection mounts to a 3-inch NPT nozzle, and the single 2-inch NPT outlet includes a sacrificial shear groove. The hydraulic actuator is easily detachable for quick cleaning or replacement without removing the entire valve from the tank. A red anodized aluminum piston/indicator gives a positive visual signal of the valve's open/closed state, with an optional extension flag (part 29209SS) available for greater visibility from the ground.
