The Zaes® needle valve manifold with needle valves made from rolled bar is the best choice for testing, testing and draining of instrumentation in your facility.
It has five valves for balancing systems with differential pressure measuring instruments, two valves for isolation (one for the high pressure and/or temperature line and one for the low pressure line), two valves for venting or draining the high and low pressure lines and a fifth valve that acts as a BY PASS and allows the instrument to be calibrated correctly.
Quality packing to ensure total circuit sealing and insulated valve trim for long life and maintenance savings.
