The air-operated diaphragm valve is the fitting solution for the shut-off, regulation, and dosing of abrasive, corrosive, and fibrous products. They are ideally suited for use with these products due to their completely free product flow, whereby a practical blocking and dead space-free fitting results.
The air-operated diaphragm valves ensure an optimal shut-off, also when used with solids, such as granules, powders, pellets, chipping, sand, cement, gravel, textile fibers, carbon, fine glass fragments, and liquids that contain solids.
This product is widely used in metallurgy, chemical industry, cement, ceramics, glass, plastics, wastewater treatment, control, food and beverage, wine, and other industries.
It is suitable for fluids containing fiber, petroleum, mineral slurry, cement, powder, slurry, sewage sludge, etc. It can be completely cut off even if it is mixed with solid substances.
Ningbo Jianai Pinch Valve Manufacturing Co., Ltd. is a professional manufacturer of pneumatic pinch valves. The company is equipped with advanced imported equipment such as machining centers and CNC lathes to ensure the quality of the valves. The core component of the pinch valve, the inner bushing of the hose is independently developed and produced by the company, and has a separate hose production workshop; technically hired a hose polymer doctor for professional research and development; established a hose laboratory to improve the service life, elasticity and wear resistance of the hose, anti-aging test, and repeated test. Through 3 years of hard work and dedication, the pinch valves produced by the company have fully reached the imported quality, with a service life of more than 600,000 times and a service life of more than two years in a normal environment. It is widely used in various industries (train industry, environmental protection industry, cement industry, animal husbandry, filling industry, etc.), and exported to all parts of the world, and is deeply satisfied and trusted by customers!
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 »
