The valves used by our customers in the production process due to the corrosive medium and the presence of particles and fouling, the use of conventional valves has problems such as short service life and serious valve seat leakage.
 
Although the valve is a small component in the entire system, it is very important in the entire production process. In order to ensure the stable, safe and effective operation of the entire production process, the on-off valve used in the production process needs to be further developed. .
 
We know that when there are particles in the medium, which are easy to scale and are corrosive, the choice of using a pinch valve can bring good results!
 
We have designed and developed special pinch valves for corrosive and abrasive conditions.
 
The working principle of the pinch valve is very simple. The only rubber liner in the pinch valve that is in contact with the medium is deformed by the external force.
 
The application field of pinch valve is very wide:
 
Pinch valve can be used in power plants, sewage treatment plants, mining, chemical process control. The pipe pinch valve is particularly suitable for fouling-prone conditions. Even if solid particles are present in the medium, it can be closed with impurities. Since the only part in contact with the medium is a rubber liner made of rubber vulcanization, it has high wear resistance Corrosion resistance, even if a complicated chemical reaction is taking place in the pipeline, the pipe clamp valve is fully capable.
 
The pinch valve we designed and manufactured has been selected by various industries and has gained a good reputation.
 
The pinch valve also has many features:
 
High abrasion and corrosion resistance: It can withstand various medium-concentration acids and alkali salt solutions of any concentration, and can transport pulp, dry and wet powder, and media with crystalline objects.
 
Full diameter: When the pinch valve is in the open state, its overall structure can be completely integrated with the piping system without changing the inner diameter and structure of the pipe, and it has no effect on the structure of the flowing medium in the pipe.
 
Non-clogging with impurities closed: The full diameter of the pinch valve is unobstructed. Because the fluid medium flows in the elastic liner, it will not scale and is self-cleaning. It can naturally achieve the effect of no clog even in the presence of solid particles In the case, the inner liner is deformed by the pressing plate, so that the solid particles are completely wrapped in the rubber. The presence of solid particles in the pipe can also achieve full-opening.
 
No leakage: There are rubber flanges at both ends of the liner. When the valve is connected to the pipeline, no additional gaskets are needed. The valve channel and the control medium space are completely isolated, and there will be no internal or external leakage. Eliminate bad phenomena such as running, running, dripping, and leaking;
 
Longer life than alloy valves: the only part of the pinch valve that is in contact with the medium is the liner, and its inner wall is made of rubber, so the inner wall is very smooth and elastic. When the medium passes through the liner, the friction between the medium and the inner wall is very small.
 
Low maintenance cost: The pinch valve is specially designed as a low maintenance valve. There is no valve seat, sealing packing, seal ring or telescopic tube that needs to be replaced regularly. The inner tube is the only part of the pinch valve that needs to be replaced. Once the inner tube is replaced, the valve Just like new valves.
 
Can replace many valves: it can replace diaphragm valve (easy to scale and often block the pipeline), gate valve (not tightly closed, easy to leak), stop valve, regulating valve, etc.
