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

· The bottom of the valve body adopts no groove design, and does not cause accumulation of impurities or dirt, thereby effectively avoiding the leakage caused by impurities scratching of the valve seat.
· The valve stem is designed with three "O" ring seal. The friction resistance of the switch can be reduced, water leakage is greatly reduced, and the sealing ring can be replaced without cutting off water.
· The screw made of aluminum bronze material, so the switch is more smooth, not easy to rust, difficult blockage.
· The overall of valve adopt non rising stem design, reducing the valve, especially large diameter valve installation space.

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