Product Description


Gate valves (gate valve) is an open/close a gate, direction and perpendicular to the direction of flow of the gate valve can only be fully open and close, unwell door parameter varies, usually for 5 °, medium temperature is not high for 2 ° 52 '.Improve the craft and make up for the deviation of the sealing surface Angle during the processing. This type of gate is called elastic gate.

Gate valve is designed as gate plate. The movement direction of gate plate is perpendicular to the flow direction. Gate valve can only be fully open and fully closed.Sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters, usually for 5 °, medium temperature is not high for 2 ° 52 '.Wedge gate valve can be made into a whole, called rigid gate;It can also be made into a gate which can produce slight deformation to improve its craft and make up for the deviation of the sealing surface Angle during processing. This type of gate is called elastic gate.When the gate valve is closed, the sealing surface can be sealed only by medium pressure, that is, the sealing surface of the gate plate is pressed to the seat on the other side by medium pressure to ensure sealing of the sealing surface, which is self-sealing.Most gate valves are sealed by force, that is, when the valve is closed, to rely on external forces to force the gate to the seat to ensure sealing cover sealing.The gate of the gate valve moves in a straight line with the stem.Usually with trapezoidal threads on the lifting rod, the rotary motion is changed into a straight motion through the nut on the top of the valve and the guide groove on the valve body, that is, the operating torque is changed into the operating thrust.When the valve is opened, when the height of the gate is 1:1 times the size of the valve, the flow channel is fully open, but this position cannot be monitored during operation.In practical use, the valve stem is marked by the vertex, that is, the open position, as its full open position.In order to consider the temperature change in the lock phenomenon, usually open to the vertex position, and then rewind 1/2-1 turn, as the full open valve position.Therefore, the full open position of the valve is determined by the position of the gate and the stroke.Some of the gate valves, stem nuts are located on the gate plate, the hand wheel turns to drive the stem to turn and the gate plate is lifted, this valve is called rotary stem gate valve, or called the dark stem gate valve.



Packing & Delivery

Industrial Gate Valve with No Rising Resilient Seat
1. Low flow resistance.The medium channel inside the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.

2. It takes less effort to open and close.In contrast to globe valves, gate movement is perpendicular to the flow direction of medium, whether open or closed.

3. Large height and long opening and closing time.Gate opening and closing travel is large, the drop through the screw.

 
4. Water hammer is not easy to occur.The reason is the long shutdown.

5. The medium can flow in any direction on both sides and is easy to install.Gate valve channels are symmetrical on both sides.

6. The structure length (the distance between the two connecting end faces of the shell) is small.

7. Simple shape, short structure length, good manufacturing technology and wide application range.

 
8. Compact structure, good rigidity of valve, smooth channel, small flow resistance, sealing surface with stainless steel and hard alloy, long service life and PTFE packing. Reliable sealing and flexible operation.
