Piston valve RDV series
برند:
Zhejiang Gute Pneumatic Machinery Co., Ltd
مشخصات:
RDV rotary disc gate valve The valve plate is driven by the rotating shaft, so that the motion of the valve switch is rotating. The piston rod of the pneumatic actuator does not contact with the medium directly, which prolongs the service life of the actuator. The sealing pair is made of hard metal, ceramics and other wear-resisting materials, which has good mechanical and wear-resisting properties. It solves the problem that the sealing surface is easy to be eroded due to material erosion and has a low life. Therefore, it has a longer service life, can bring ideal use effect and economic benefit to users, and is conducive to equipment maintenance and operation adjustment, so as to make the overall operation safe and economical. Significant improvement.
Scope of application
It is suitable for opening and closing of gas and slag in dry ash system of power plant, as well as for opening and closing of abrasive, corrosive, powder and flue gas in mines, steel, papermaking and petrochemical industries.
Characteristic
1. There is no obstruction in the full circulation of the inlet and outlet, and there is little ash trapping and accumulation.
2. Good wear resistance and long service life.
3. There are directional requirements when the valve is installed and used, and the flow direction of the medium should be consistent with the sign on the valve.
4. Compact structure and convenient installation.
Key Points of Installation and Use
1. Read this instruction carefully before installation, and check valve type, size and technical parameters.
2. It is strictly forbidden to Weld flanges after installing valves. The valve installation distance reserved
