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 three valves for balancing systems with differential pressure measuring instruments, two valves for isolation (one for the high pressure and/or temperature line and another for the low pressure line) and a third one that acts as BY PASS and allows the correct calibration of the instrument.
Quality packing to ensure total circuit sealing and insulated valve trim for long life and maintenance savings.
