Gate Valve Cast Steel PN16 Z41H-16C High Quality

Product Description:

1.Structure of Gate Valve Description：
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.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. 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

1. What is the work principle of gate valve ？
The gate faces can form a wedge shape or they can be parallel.

Because of their ability to cut through liquids, gate valves are often used in the petroleum industry.
2. 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.
