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:The expert can tell me how to install this valve, and what fittings to use on both sides
- If the process permits, you can first weld on both sides of the flange, modified into a flange butterfly valve, and then installed on the pipe, easy to overhaul later
- Q:What's the advantage of using three way valves?
- Three way valve generally has a cut-off, regulation, diversion, and prevent counter flow, voltage regulation and overflow and other benefits, because of its benefits more, so the use of the three valve is extremely extensive, in the valve industry is also very important.
- Q:How about the valve?
- The British Hudson Valve Co. Ltd. (HUDDERSFIELD VALVES LIMITED), founded in 1964, its predecessor for the British metal parts company (ART METAL FABRICATION LTD AMF, referred to as LTD), located in the world famous one of the UK's Huddersfield valve production center (HUDDERSFIELD), the main production of various kinds of valve, valve cage valve and other valve manufacturers supporting. .
- Q:What do the Z, J, H and D represent in the valve type?
- 7, pairs of clipsThe transmission modes of valves are code 9, 6 and 3 respectively:9, electric, 6, pneumatic, 3, turbo wormBody material code Z, K, Q, T, C, P, R, V, respectively:Grey cast iron, malleable cast iron, ductile iron, copper and alloy, carbon steel, stainless steel, chrome nickel chromium nickel molybdenum stainless steel, chromium molybdenum vanadium steelSeat seal or lining code R, T, X, S, N, F, H, Y, J, M, W, respectively
- Q:Where is the Shandong valve? How about joint valves in Shandong?
- Shandong valve factory is not much, but I know there is a good valve in Shandong area is doing the best, you can Baidu search Shandong valve factory in Shandong united, they do Weifang, the quality of the valve is good, the price is not high, I was with the valve dealer customers are from there I can purchase online, Baidu their company name Shandong valve contact him specific you
- Q:such as gate valve, three way plug valve
- The lower part of the pressure gauge installed water pipe, there are water, avoid high temperature, medium pressure gauge contact directly cause damage, so regular cleaning, in order to avoid congestion, three way plug function is used for flushing, please see "how to operate them.".
- Q:Excuse me American Standard pressure test valve GB standards are much ~ is how much valve pressure can play much pressure? Thank you
- Strength test is nominal pressure of 1.5 times, the test time is 5min, the test time, the valve body is not broken, no deformation, the valve is not leaking water, the pressure gauge does not drop to qualified. After the strength test has passed, the tightness test is carried out. The tightness test pressure is equal to the nominal pressure. The valve does not leak in the test time, and the pressure gauge does not drop to be qualified.
- Q:Why is copper used in cryogenic valves?
- The rigidity of copper is better, and the friction parts are not easy to produce adhesion. The influence of temperature on copper is smaller than that of steel. Especially in the valve stem, there is also the important gear part, copper!
- Q:someone else's home has valves, but also checked nothing, in addition to telephone repair, there are other ways? emergency
- You should live in a high-rise, if there is no power failure, that is, the water tank pump failure, and urge property repair is.I hope I can help you
- Q:What is the term "Z41H-16C" on the line?
- When Z41H-16C opens the valve, when the gate lift height is equal to 1:1 times the valve path, the passage of the fluid is completely unblocked, but at run time, this position is not monitored. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position. Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.
