Flanged gate valve F4 double bonnet 4 inch water gate valve
The valves disc is rubber-packed to get excellent sealing effect by the rubber's resilient deformation.

Non-rising resilient seated gate valves solve the problem in general gate valves such as leakage, rusting etc.and saves installation space. It is used widely in tap water industry, sewage treatment, shipping construction,petroleum, chemicals, food, pharmacy, textile, electric power, metallurgy and energy system's pipeline to adjust and shut off fluids.

 

Product Advantage
1,The valve body is made of precision casting, the precise geometry makes the north of the valve body not need any finishing, so as to ensure the tightness of the valve.

2,The body is made of ductile iron QT450-10, shall not be broken by transportation, collision or installation.

3,The valve body adopts streamlined design, so that the medium moves straight in the valve cavity, the flow resistance is smaller and the flow area is larger.

4,The valve adopts bidirectional sealing design, and the installation direction and medium flow direction are not limited.

5,The inside and outside of the valve bodyadopt powder epoxy resin electrostatic coating, which can effectively prevent corrosion and rust caused by contact between valve body and medium, and can be used in sewage system.

6,The valve plate adopts high-quality overall rubber coating, the use of advanced technology makes the vulcanized rubber vulcanization after the valve plate to ensure accurate geometry, and the rubber and ductile iron gate connection is firm and not easy to fall off with good elastic memory, so as to ensure the stable performance of the valve sealing.

7,The screw made of aluminum bronze material, so the switch is more smooth, not easy to rust, difficult blockage.
