Description

HAP Pneumatic Diaphragm Low-Temperature Single-Seat Control Valve

HAP pneumatic diaphragm single-seat control valves are widely used in industrial sectors such as air separation equipment, oxygen generators, petroleum, chemical industry, metallurgy, and power stations. They control the flow of low-temperature media and are suitable for occasions with strict requirements on leakage.

Flow coefficient is shown in Tables 1 and 2 Table 1
