The double-stop relief plug valve and the relief function valve are suitable for aviation kerosene, crude oil, light oil, natural gas, liquefied gas, pipeline gas, chemical medium and other pipelines, as an ideal device for cutting off the medium.
1. During the opening and closing process of the valve, the sealing surface of the valve body does not have any contact with the sealing surface of the sliding blade, so the sealing surface has no friction and wear, the service life of the valve is long, and the switching torque is small;
2. When the valve is repaired, there is no need to remove the valve from the pipeline, only need to disassemble the bottom cover of the valve and replace a pair of sliding vanes, which is very convenient for maintenance;
3. The valve body and are full bore, the medium has no flow resistance when passing through the valve, and the pipe can be cleaned through the ball, which overcomes the shortcomings of the reduced diameter valve;
4. The inner cavity of the valve is plated with hard chrome, and the sealing area is hard and smooth;
5. The elastomeric seal on the sliding vane is made of fluoroelastomer and molded into the groove on the surface of the sliding vane. metal-to-metal seals with fireproof functions as backing for elastomeric seals;
6. The valve has an automatic bleed device (optional), which prevents the valve cavity from abnormal pressure rise and tests the effect of the valve after the valve is completely closed;
7. The valve switch indicator is synchronized with the switch position, which can accurately display the opening and closing status of the valve.
