Aviation kerosene, light oil, natural gas, liquefied gas, pipeline gas, chemical media and other pipelines are ideal devices for cutting off media.
① During the valve opening and closing process, there is no contact between the sealing surface of the valve body and the sealing surface of the sliding vane. Therefore, there is no friction and wear on the sealing surface, the valve has a long service life and a small switching torque
② During the maintenance of the valve, it is not necessary to remove the valve from the pipeline, only the bottom cover of the valve needs to be disassembled, and a pair of sliding blades can be replaced, and the maintenance is very convenient;
③ The valve body and the plug are reduced in diameter, which can reduce costs;
④ The inner cavity of the valve is plated with hard chrome, and the sealing area is hard and smooth;
⑤ The elastic seal on the slide is made of fluoro rubber, and it is compression-molded in the groove on the surface of the slide. Fire-resistant metal-to-metal seals as backings for elastic seals;
⑥ The valve has an automatic relief device (optional). After the valve is completely closed, prevent the valve chamber from abnormally increasing pressure and check the effect of the valve;
同步 The valve switch indicator is synchronized with the switch position, which can accurately display the valve switching status.
About sealing:
The elastic sealing ring is molded in the groove of the sliding plate. As the sealing slide moves to the inlet and outlet of the valve, the sealing circle is gradually pressed into the groove. The mechanically processed surface of the sliding plate and the valve body cavity form Grade gold-to-metal seal prevents the elastic seal circle from being pressed further, and has a fireproof function.
Double off and double off and release:
This is a method to completely shut off the pipelines at both ends by 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 an open relief valve.
Double seal method:
Two independent sealing slides are pressed at the upper and lower ends of the valve hole (double shutoff). When the valve is closed, the relief valve is opened to check the sealing effect (bleed).

Preparation of specifications:
The design and manufacture of the valve are in accordance with API16D; the structural length of the valve is in accordance with ANSI B16.10; the flange connection size is in accordance with ANSI B16.2.
