Air operated pinch valves are also known as pneumatic pinch valves and rubber sleeve valves. Because the valve core part uses a hose, its airtightness, corrosion resistance, and wear resistance are far superior to metal valves. Therefore, it is widely used in smelting, mining, electric power, chemical, pharmaceutical, starch, paper, food, brewing, and other industries. Its excellent sealing performance and durability in harsh environments have unparalleled advantages, which is the trend of medium and low-pressure valves. However, due to the limitations of the hose, its high-pressure resistance is a weakness.
1) Design science
Low flow resistance, no blockage, no gaps, and dead angles hinder the operation of the valve. When the medium has residual particles, the hose can wrap it in the middle, and the pinch valve can still achieve zero leakage closure.
2) The control is very convenient
You can operate according to your own specific requirements, and you can perform automatic control locally or remotely.
3) Strong wear resistance and corrosion resistance
Rubber is far more wear-resistant than steel, iron, and other various metal materials, and the adjustment of the formula can resist corrosion of various chemical solvents, so it is especially suitable for particle slurry and chemical media pipeline transportation control.
4) Excellent sealing
Rubber flanges are provided at both ends of the hose. When the valve is connected to the pipeline, no additional sealing gasket is needed. The valve channel and the control medium space are completely isolated, and there will never be internal and external leakage, thereby eliminating undesirable phenomena such as running, emitting, dripping, and leaking;
5) Good cold resistance
Since the fluid medium flows in the elastic hose, the effects of freezing and cracking of the shell caused by the crystallization of the fluid are eliminated.
6) Simple installation and operation
There is no directionality and no confusion during valve installation.
7) Long service life
The JIA NAI pneumatic pinch valve has high-quality rubber sleeves with reinforced cords, so it can withstand any high-frequency opening and closing operations.
8) Reasonable structure
If the rubber sleeve of the pinch valve is found to be damaged, its structure can realize the rapid replacement of the rubber sleeve, convenient maintenance, and easy operation.
9) Low maintenance cost
As long as the hose is replaced during maintenance, the valve body and other mechanisms can be used for a long time, which greatly saves the user's production cost. Moreover, the full diameter of the pipe clamp valve is unobstructed, non-scaling, and self-cleaning, so that the pipeline does not need to be manually cleaned, and the maintenance cost is low.
10) Wide range of uses
It can replace diaphragm valves (easy to foul and often block official roads), gate valves (not tightly closed, easy to leak), stop valves, regulating valves, and can withstand various medium-concentration acids and alkali salt solutions of any concentration. Air operated pinch valve can transport ore pulp, wet and dry powder, and medium with crystalline objects. Different media can be equipped with different rubber formula hoses to meet the production needs of different users.
China's pinch valves are world-renowned for their excellent quality and low prices. This has also attracted buyers from all over the world to come to China to purchase pneumatic pinch valves. However, how to choose the best among many suppliers is a problem that everyone cares about. Today we will m Read More »
The hose pinch valve has applications in many areas of life, especially in industry. It is a type of valve product with rubber sleeves as seals and opening and closing parts. The handwheel drive drives the up and down movement of the upper and lower valves to achieve the opening and closing effect. Read More »
The higher the quality of the air-operated pinch valve inner bushing, the longer the service life of the pinch valve and inner bushing. The long service life of the inner sleeve of the pinch valve means that the maintenance cost of the equipment is low. The replacement of the inner bushing of the ai Read More »
