Profile
Pinch Valves, also known as hose valve,It's our new product according to the latest standards to designed and manufactured ,In modern industry,Some Solid or Liquid medium (containing granules, powders, fibers, sticky pulp) of abrasive substance or chemical processes with corrosive media,will transport by pipeline，Pinch Valve is the best choice.
It can be used in：
Sewage treatment plants (sludge, sand cleaning, raw sewage, lime, carbon slurry),
Power plants (FGD systems, ash handling system, coal transport),
Mining (tailings, flotation control,mud pipelines,tailings filling,many areas of various other slurry),
Chemistry (corrosive and abrasive media, powder, granules) and paper mills, pulp mills, electronics industry, food industry, cement, sand, glass etc.
Suitable for all corrosive, non-corrosive gas, liquid, semi-liquid and solid powder medium, To be intercepted and regulation,It can be installed in any position.
Feature
1、Unobstructed flow path, full bore
2、Low flow resistance
3、Without blocking
4、Could close in Zero leakage when there are residual particles
5、Without gaps and corners hinder valve operation
6、Low maintenance costs
7、Simple design, free from external adverse environmental impacts
