Ductile Iron Casting Flange Type Resilient Seated Gate Valve in Water Plant Power Plant

1) Description

Flange type resilient seated gate valve is made of high quality ductile iron casting and become, has high strength, light weight, the characteristics of the geometry size accurate, using flexible disc produce trace deformation compensation effect, achieve good sealing effect, with driving gear, a person can very easily switch, also can be equipped with electric, pneumatic actuators according to the user's requirements.It can be widely used in water supply, sewage water, construction, video, electric power, medicine, metallurgy, light spinning, energy systems and other fluid pipelines as regulating and intercepting devices.(optional driving mode: manual/spur gear/bevel gear/denso, etc.)

 2) Features

1. Integral laminating: the valve adopts integral laminating, with good covering performance and geometric size, ensuring reliable sealing and long service life.

2. Light weight: the valve body is made of ball iron, light weight and easy to install.

3. Flat valve seat: the same flat valve seat design as the water pipe is adopted at the bottom to avoid sundry deposition and provide reliable sealing.

4. Corrosion resistance: the inner cavity is coated with epoxy resin to prevent corrosion and rust. It can be used not only for drinking, but also for sewage system.

5. Three "O" seal: the valve is sealed by three o-rings, with small frictional resistance, light switch and no water leakage.1) Execution standard:

 2) Technical parameters：

1) Operating principle:

Gate valve by valve body, valve cover, disc, stem, seat, stent, such as the sealing parts. 

 gate structure classification of many.When the hand-wheel (or other driving device) rotates counterclockwise, drive the stem nut to rotate, then the stem nut drives the stem to rise, the stem drives the gate to rise upward, until the gate is fully opened, then the medium at both ends of the valve body channel flows;When the hand-wheel turns clockwise, the stem nut drives the stem down, thus driving the gate down, until it is completely closed, then the valve body channel medium stops the flow.

2) Main parts and material.

Application:

Water, sewage, construction, petroleum, chemical, food, medicine, textile, electricity, ships, metallurgy, energy systems and other fluid pipeline as a regulation and interception device.
