  • Technical Feature

    OPERATION:

    The valve maintains a constant flow rate out of ② regardless of load pressure changes in the circuit downstream of ②.The fixed control orifice is factory preset to customer flow specification.

    The valve begins to respond to load changes when the flow through the valve creates a pressure differential across the control orifice greater than 5.5 bar, with accurate flow maintenance from 7.6 to 240 bar. Reverse flow( ② to ① )returns through the control orifice and is non-compensated.
