Overview
Diaphragm valve
Product Details
ZXT ZSQT pneumatic thin film, piston diaphragm regulating valve (referred to as pneumatic diaphragm valve) adopts the "mountain" shaped protruding surface between the diaphragm and the valve body for sealing, isolated from the outside world (without stuffing box), the flow path of the valve body is simple, smooth, and can be covered with anti-corrosion layer, suitable for corrosion resistance and highly toxic occasions.
The nominal pressure classes of this series of products are 0.6 and 1.0MPa, the diameter of the valve body ranges from 20 to 200mm, the applicable temperature ranges within 150℃, the leakage volume is zero.
Note: parameters are for reference only, or incomplete. Valves can be selected according to the requirements of different pressure, material, diameter, driving mode. Please contact us by phone or online.
