5 Valve Manifolds-Instrumentation Manifolds Orifice Size 157 in. (4.0 mm), 5M-501R are designed for differential pressure applications. 5-valve manifolds consists of high pressure valve, low pressure valve, balance valve and two check (blowdown) valves. 5-valve manifolds is used for all kinds of imported instruments, and it is installed with all kinds of differential pressure, flow, liquid level and other transmissions. When working, close the two groups of checking valves and balance valves. If inspection is needed, just cut off the high pressure and low pressure valves, open the balance valve and two check valves, and then close the balance valve to calibrate and balance the transmitter.
