High Quality DI Soft Seated Gate valve Flange End DN50-DN800

High Quality DI 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

· Good and clear body marking

· The soft seal gate valve uses ductile iron as the valve body material. The overall weight of the valve is 20%-30% lighter than the traditional gate valve. The lighter weight makes the soft seal gate valve easier to install and maintain.
· The valve body of the soft sealing gate valve is coated with non-toxic epoxy resin, and the gate is completely wrapped by rubber, which can effectively prevent the inside of the valve body from being corroded by the medium in the pipeline.
· The valve stem of the triple “O” seal ring seal design greatly reduces the friction resistance of the soft seal gate valve when it is closed, and the sealing performance is reliable, and no water leakage occurs; the unique design structure also makes the “O” seal ring It can be replaced under pressure and is maintenance-free.

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