Pneumatic diaphragm control valve description

Pneumatic diaphragm regulating valve adopts diaphragm,It is sealed with the "mountain" convex surface between the valve body and isolated from the outside (no stuffing box). The valve body flow path is simple and smooth, and can cover the anti-corrosion layer. It is especially suitable for corrosion-resistant and highly toxic occasions.
 The applicable temperature range is no more than 150 °C, the leakage value can reach VI  level, even zero leakage.
