4 way diverter valve consists of the valve body, the diverter plug, SID gauge assembly, differential check valves, and the lift, turn and seat operating mechanism. It is designed primarily for bi-directional meter prover service where its function is to divert the flow streams in opposite directions through the prover and to provide a means of proof that the flow streams are separated.

4-Way Direct Acting Valves are available on 4-way valves which meters exhaust flow from each working port to exhaust port of valve. The 3-way valves can be configured by mounting valve 180° in opposite direction. These are featured with 12 and 24 Vdc coils rated for mobile voltage operation.

5-valve manifolds are designed for differential pressure applications. These are metal-seated with a globe configuration designed for high -temperature service. The seat is a free-swiveling stainless steel ball sealing on a line contact at the orifice. This manifold is utilized with various types of transmitters used to measure differential pressure.

Actuated needle valve has two separate air inputs: One for valve actuation and one for fluid distribution. It is also used to maintain fuel level slightly below the edge of the discharge nozzle. The body is constructed of electroless nickel plated brass. This valve is available in many different sizes and configurations.
