Product Description

HAN Pneumatic Diaphragm Low-Temperature Double-Seat Control Valve

HAN pneumatic diaphragm low-temperature double-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 general sealing requirements.

Flow coefficient Kv is shown in Table 1 Table 1
