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. 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. 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. Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow. Typical gate valves are designed to be fully opened or closed.When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.
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
• Environmental protection and energy saving
• Good visual effect

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 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.

- Q:GB 300 gate valve, a multi?
- GB DN300 flanged gate valve, PN10 manual 245kg bevel gear 315Other pressure levels, please specify specific pressure.Wenzhou Chaoda group Agel Ecommerce Ltd to provide the answer:
- Q:Gate valve Z41H-16Q generally used for what place?
- Commonly used in petroleum, chemical systems, especially in long-distance pipelines of petroleum and natural gas.
- Q:What's the meaning of the gate valve model z41x 16Q?
- Gate valve (Z) flange connection (4) wedge type single gate (1) rubber soft seal (X) -16 pressure) (Q)
- Q:Which is more expensive, bronze gate valve or brass gate valve?
- The advantage of casting method is more obvious. The casting of stainless steel is much more difficult than that of brass.
- Q:What is the difference between an elastic gate valve and a rigid gate?
- Brief introduction: the valve gate valve is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'.Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.
- Q:What are the main types of gate valves?
- According to the different materials for carbon steel valves, forged steel valves, stainless steel valves, cast steel valve, iron gate, ceramic valve;
- Q:Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?
- the valve before the pressure measuring point, distance of valve straight pipe length is 5 times the diameter of the valve after the pressure valve, the distance is 10 times the diameter of straight pipe length.
- Q:Is the gate valve clockwise or closed?
- In general, the valve is clockwise turn off, in the case of special requirements under the opening.
- Q:What is the difference between cut-off valve and gate valve?
- Simply put, the cut-off valve is one-way, only into, do not give up, the valve is two-way
