DIN flange cast iron gate valve Introduction
Resilient seated gate valves made of speclal rubber elastlcly full wrap-plece valve structure, and the general absence of gate leakage or rust compared to other phenomena. Overcome their common seal bad, elastic fatigue, wear rubber aging and Sealing ruts and other defects、 Produced by ths elastic saeling full compensation of small quantities of deformation to achieve a good sealing effect. It can be widely used in water supply, petrochemical, metallurgy, shipbuilding, food, pharmaceuticals and energy systems and other fluid line is used as a regulator and shut-off devices.
