Big Size Metal Seated Ductile Iron Gate Valve

• cast iron gate valve
• Flanged Gate Valve

This gate valve allows for two – way flow direction and used for closing or opening the medium flow. This valve can be installed in horizontal and vertical positions in the piping systems.
The valve adopts full – shut structure which has good protection function and can be used in all weather.
Can use all sorts of pipg flange standards and flange seal face form, meet various needs of the project and use requirements.
Flat plate design, floating seats, bypass design, all lead to lower operating torque.
The sealing surface of the valve adopts abrasion- resistant and anti-corrosive materials which can lengthen the performance life of the valve.
The wedge is replaceable without needing to remove the valve from the pipelines.
It is designed with straight through bore type with non-rising stem, inside screw and bolted bonnet.
This valve provides positive shutoff with inimal pressure drop and flow turbulence.
