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. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. For extremely thick fluids, a specialty valve often known as a knife valve is used to cut through the liquid. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening.

2. Main Features of the Gate Valve:
1, Small fluid resistance >
2, A smaller external force required to open and close
3, Unrestricted flow of medium
4, The erosion of working medium in sealing surface is smaller than globe valve when open fully.

5.FAQ
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 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.

Q:The difference between cut-off valve and gate valve
Structurally, the gate valve for the gate, down to the front and back seat seal; globe valve with spherical, taper and flat spool, down to the valve seat seal. Functional stop valves are generally used for pressure flow control. Gate valves are used for isolation.
Q:Soft sealed gate valve and hard sealing gate valve which good?
If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.
Q:Gate valve type Z40Y, Z40H letters - what does that mean?
According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange0== structure: wedge type elastic RAMY== sealing surface material: hard alloyH== sealing surface material: Cr13 stainless steel
Q:What does the gate valve 150# mean?
It's the stress PN, the 2.0MPA150# is the ANSI standard -- American National Standards InstitutePN is nominal pressure
Q:What is the soft seal gate valve?
Cautions for installation and maintenance of soft sealing gate valve:For double gate valves, the direction of installation shall be in the vertical position of the valve stem, and the handwheel at the top.The installation of the soft gate valve shall be carried out in strict accordance with the installation environment, installation conditions and installation procedures on the factory manual.After installation, the soft seal gate shall be periodically checked for performance and killed in the cradle before any undesirable conditions occur.
Q:What do you mean by "2" and "200 CF8M"?
CF8M is 316,2 "is 50200 caliber stainless steel pressure (American Standard, LB)
Q:Which is more expensive, bronze gate valve or brass gate valve?
But the obvious weakness of brass is its poor strength, relatively large volume, and its lack of corrosion resistance.
Q:What is the difference between the model z81x-16q and z81x-16c of the groove gate valve?
Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel
Q:What is the difference between the copper gate valve and the ordinary material gate valve?!
The copper gate valve is made of copper alloy, and the common materials are made of stainless steel, cast steel, cast iron, and so on. Now there are new types of ceramic gate valves. Different properties of the gate valve performance, processing technology, service life, applicable occasions are a certain difference. Copper gate valves should be used for fire end water outlet installations as well as other occasions with special requirements.
Q:Why is gate valve or butterfly valve used for water pump?
General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment
