Chinese Superior Price Soft Seated Gate Valve Flange End DN50-DN800

Chinese Superior Price Soft Seated Gate valve Flange End DN50-DN800

1.PRODUCT PROFILE

Soft seated gate valves, in ductile iron GGG40 or GGG50 with flat body and EPDM covered wedge, are suitable for drinking water applications, being coated with epoxy powder painting, not toxic. This kind of gate valves are inside screw, with non rising stem in SS420, wedge EPDM vulcanized and sliding rails on the body. The soft seated gate valves are full bore, have no pressure drops, with the EPDM covered wedge that is not affected by corrosion and that doesn’t need any maintenance. In case of need, o-rings on the stem can be replaced with the valve in the pipeline and in complete open position. Soft seated gate valves in ductile iron can be installed above or under the ground level, or in chambers.

2. FEATURES

· Full bore design

· Self cleaning & low pressure loss

· Rolled stem ensure smooth thread edges and double thread

· Low operating torque

· Inner and outer surfaces are coated with minimum 250 microns fusion bonded epoxy. 300 microns is available.

· Suitable to use with aboveground and underground applications. Can be operated with actuator, gearbox, handwheel and extension spindle.

· The top of the shaft bearing and shaft nuts are made of MS58 brass. High precision machining enables low operation torques.

· Full bore characteristics without distruption of flow results in low pressure drops across the valve.

· Every valve be 100% tested and qualified before packing and delivery
