DIN 3352 Gate Valves, ASTM A216 WCB, DN250, 10 IN, PN16, RF

This DN250 (10-inch) wedge gate valve from our China DIN 3352 factory is cast in rugged ASTM A216 WCB carbon steel, rated to PN16 / Class 150 LB, and finished with raised-face RF flanges for easy, reliable installation. A smooth handwheel drive gives positive shut-off in water, oil or steam lines, combining robust cast body integrity with the proven sealing performance of a solid wedge design.

Wedge Gate Valves are engineered and manufactured to achieve volatile organic compound (VOC) leakage rates of less than 100 ppm. Comprehensive baseline laboratory testing, including static and cycle evaluations, has identified critical design parameters essential for ensuring low-emission sealing in both the stem packing and bonnet gasket areas. An in-house testing procedure has been developed and is routinely conducted to verify that standard design and manufacturing processes consistently meet the maximum 100 ppm VOC leakage requirement before shipment.
