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.This means that flow rate does not change evenly with stem travel. Also, a partially open gate disk tends to vibrate from the fluid flow.
2.Main Features of the Gate Valve：
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.
Stem is designed to be rising stem and non-rising stem, with a clear sign for valve opening.
Drive mode falls into manual, hydraulic and gear.
Combining type falls into flange, thread and hub.

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: Where is the Shanghai valve? What brand is good?
- A lot of Shanghai brand brand of Shanghai KaiWeiXi, Department of finance the Kemei high Lidun Shanghai Karon these are good
- Q: What is the main function of the valve?
- Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure. Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.
- Q: What does "TD671F" mean?
- TD671F is pneumatic clamp type soft sealing butterfly valveValve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
- Q: Which brand of electric valve is good?
- Electric valve does not need to use imported, domestic boutique can meet.
- Q: Can the gas valves be switched off regularly?
- No one at home, there are children, stove use time is relatively long, the gas hose has not changed for a long time, as far as possible off the stove front valve. Regular checks are necessary. For a long time, try the stove before the valve is intact, hose aging, safety first. Selection of large brands of stoves, quality guaranteed
- Q: Which direction is the valve? Which direction is it?
- Generally: clockwise, counterclockwise, looseYou can also see the logo on the spool
- Q: What does the valve QF mean?
- Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.
- Q: What is the difference between a stop valve (a power station valve) and other valves?
- Power station cutoff valve advantages editor1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section.2., simple structure, small size, light weight.3., reliable and reliable, the current gate valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.5., easy maintenance, simple valve structure, sealing ring is generally active, disassembly and replacement are more convenient.6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
- Q: Tell me the exact address, or the phone number in the market. Where is the industrial zone (the valve) in Hefei? Please help, thank you
- At the intersection of Mingguang Road and Shengli Road, the southwest side is all made of valves
- Q: someone else's home has valves, but also checked nothing, in addition to telephone repair, there are other ways? emergency
- That's a lie. Other people's homes do not necessarily have water.You need to keep on pressing the property.
