Product Detail

The jacket ball valve has good heat preservation and cold preservation characteristics, and the valve diameter is the same as the pipe diameter, and a

Design: API 6D; face to face: ASME B16.10; pressure-temperature: ASEM B16.34; No friction during open/close for seal of body and slider; online maintance supported, just need to open the bottom cover. body and plug is reduced bore. Dual Expanding Plug Valve, suitable for: aviation kerosene, light oil, natural gas, liquefied gas, pipeline gas, chemical media and other pipelines, to provide top level reliable shut off function. Valve closed: When the valve is closed, first rotate the hand wheel to rotate the cock and the sealing slide by 90 degree, and then the cock moves downwards. With the movement of the cock, the sealing slide is pushed to the cover of the inner cavity of the valve until the elastic sealing ring is evenly squeezed to The upper and lower ends of the valve hole form a seal. Valve open: When the valve is opened, first rotate the handwheel to lift the cock and pull the sealing slide back from the sealing surfaces on both sides of the valve body. When the sliding plate is completely retracted and separated from the sealing surface of the valve body, continue to turn the handwheel to rotate the cock and the sealing sliding plate by 90 degree, and the valve is in the open position. About sealing: The elastic sealing ring is molded into the groove of the sliding plate. As the sealing sliding plate moves to the inlet and outlet of the valve, the sealing circle is gradually pressed into the groove. The surface of the mechanically processed sliding plate and the inner cavity of the valve form two parts. The grade gold-to-metal seal prevents the elastic sealing circle from being continuously pressed, and has a fire-proof function. Double-off, double-off and venting: This is a method to completely isolate the pipelines at both ends through two shut-off valves and a relief valve in the middle. Closing the two main valves and opening the relief valve can improve the safety of the system. If the first valve leaks, the leaked medium can be led out by the opened relief valve. Double sealing method: Two independent sealing slides are pressed tightly at the upper and lower ends of the valve hole (double shut-off). When the valve is closed, the relief valve is opened to check the sealing effect (discharge).

Valve closed:
When the valve is closed, first rotate the hand wheel to rotate the cock and the sealing slide by 90 degree, and then the cock moves downwards. With the movement of the cock, the sealing slide is pushed to the cover of the inner cavity of the valve until the elastic sealing ring is evenly squeezed to The upper and lower ends of the valve hole form a seal.

Valve open:
When the valve is opened, first rotate the handwheel to lift the cock and pull the sealing slide back from the sealing surfaces on both sides of the valve body. When the sliding plate is completely retracted and separated from the sealing surface of the valve body, continue to turn the handwheel to rotate the cock and the sealing sliding plate by 90 degree, and the valve is in the open position.

About sealing:
The elastic sealing ring is molded into the groove of the sliding plate. As the sealing sliding plate moves to the inlet and outlet of the valve, the sealing circle is gradually pressed into the groove. The surface of the mechanically processed sliding plate and the inner cavity of the valve form two parts. The grade gold-to-metal seal prevents the elastic sealing circle from being continuously pressed, and has a fire-proof function.
Double-off, double-off and venting:

This is a method to completely isolate the pipelines at both ends through two shut-off valves and a relief valve in the middle. Closing the two main valves and opening the relief valve can improve the safety of the system. If the first valve leaks, the leaked medium can be led out by the opened relief valve.
