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. 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.
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: What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve
- Stop valve and gate valveThe working principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!Gate valve and stop valve are shut-off valve, is the most common two valves.From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.

- Q: Notes on flat gate valves
- Use, maintenance, maintenance and precautions1. valve before leaving the factory have made strength and sealing test, the use of all connections should maintain the initial state.2. this series of valve operating handwheel is marked with open and close rotary direction, and the upper part of rod is equipped with open and close height gauge for regulating indication.3. when the valve and pipeline welding, the valve should be opened, appropriate to protect the neck with moisture, minimize heat conduction, to prevent damage to the sealing packing parts.4. when the valve is closed, the lever shall not be used. When the gate is closed to the top, the handwheel shall be turned 1/2 so that the gate is in a floating state.5. in the use of the valve should be regularly to the valve cap injection grease joint into the quantitative grease.6., the valve in use, such as vulnerable parts and leakage, should be replaced in time.7., the valve in the overhaul process, the cavity should be cleaned, the assembly should be added to the transmission parts of grease.8. valve storage during the shutdown, the gate should be in the closed position, long-term storage should be placed in ventilated dry place, regular inspection and maintenance.
