Product Description:

1.Structure of Gate Valve Description:
A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry.

2. Main Features of the Gate Valve:
• Valve body cavity using non-toxic epoxy resin,both inside and outside flashboard completely is coated with rubber
•  Free of water pollution
• High manufacturing accuracy
• High strength
The sealing surface of valve seat and gate is overlaid (surfaced) with hard alloy, resistant to corrosion and abrasion.
Valve seat, gate and stem are sealed with imported lip-shaped combined seal structure, so they are safe and reliable, and the switching torque of valves is low.
Simple and safe design of valve gate and seat, makes it easy to change without special tools.
Non-rubber seal effectively protects valve chamber from mud, sand and rock, etc.
Stem sealing can be changed under pressure.

1. What's are the characteristics of gate valve?
The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel.
2. What is the work principle of gate valve ?
 The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry.
3.  What is the structure?
Bonnets provide leakproof closure for the valve body. Gate valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.
