Overview of Electric Hard Seal Flat Gate Valve

Electric hard seal flat gate valve is a gate valve designed for oil pipelines, with a guide hole welded with 8-shaped hard alloy Stellite. The lower seal and hard seal valve seat have a reasonable hardness difference, ensuring that the gate of the hard seal flat gate valve will not be scratched when in the open state. Our company has also made special improvements to the valve seat structure of hard sealed flat gate valves, which can achieve zero leakage sealing effect without injecting sealing grease. Electric hard sealed flat gate valve can be used as an adjustable flat gate valve, which can be remotely operated. It has a simple structure, is safe and reliable, has low switching torque, and has a long service life.

Structural characteristics of electric hard seal flat gate valve

1. The electric hard seal flat gate valve seat adopts an O-ring seal and a floating seat structure with pre tension force, which enables bidirectional sealing of the inlet and outlet of the flat gate valve. The opening and closing torque of this structure is only half of that of ordinary valves, making it easy to open and close the valve.

2. When the electric hard sealed flat gate valve with a guide hole structure is fully opened, the channel is smooth and straight, the flow resistance coefficient is extremely small, there is no pressure loss, and it can clean the pipeline with a rough ball.

3. The electric hard seal flat gate valve adopts a packing structure with self sealing ability, which does not require frequent adjustment. It is extremely lightweight to open and close, and the sealing performance is reliable. The packing box is equipped with an auxiliary sealing high-quality injection structure, and the sealing performance is absolutely reliable. In addition to PTFE packing, it also has a triple sealing structure filled with O-ring sealing sleeve, truly achieving zero leakage and solving the problem of the most common valve packing leakage.

4. When the electric hard sealed flat gate valve is closed, it can automatically release the high pressure inside the chamber, ensuring safe use.

5. The gate of the electric hard seal flat gate valve is made of welded 8-shaped hard seal alloy, with a thickness of 2CM. The lower seal and hard seal valve seat have a reasonable hardness difference, ensuring that the gate of the hard seal flat gate valve will not be scratched when in the open state.

Precautions for using electric hard seal flat gate valve:

1. Say the important thing three times: don't push yourself to the brink of death! Don't push yourself to the brink of death! Don't push yourself to the brink of death!

2. When opening or closing in place, the valve stem handle or handwheel should be rotated 1/2 turn. To ensure that the gate is in a floating state and maintain good sealing performance.
