Pneumatic Diaphragm Low-Temperature Control Valve

ZXSD series pneumatic diaphragm low-temperature control valve is a valve applied in the low and cryogenic occasions for it uses long-necked valve lid to keep temperature. As a whole, it is of compact configuration, light weight, motion agility, and limited loss of pressure drop, large valve capacity and exact flow characteristics. The valve angular body structure is made by precision casting, with aluminum alloy material, which has good low temperature resistance, bellow pipe seal guarantees zero leakage at low temperature, such it is applied in the metallurgy, air separation, oxygen, petroleum, chemical industry and other low-temperature, cryogenic occasions. The DN range: (mm)20-100 (3/4"~10″);PN range:(Mpa)0.6/1.6/1.0(ASME Class 150.

This series of products have two sets of installation: connecting plate type, and floating model.
