Pinch Valve
- 【Introduction】:
- 【 Capacity 】:
- 【Improvement】:
【Advantages】
High resilience rubber liners with rubber boss, no leakage Smooth internal surface makes slurry flow stably and fast without flow resistance The rubber elasticity exceeds 80%, the slurry will not cause water hammer impact. Valves liners have strong anti fatigue ability, longer service life Easy to replace, simple structure and convenient operation High resilience rubber spool, more flexible and reliable opening and closing
【Product Structure】
Wear-resistant Pinch Valve is composed of upper grip, valve body, rubber spool and lower grip

【Successful case】
An Indonesian mineral processing plant chose pinch valve to control the opening and closing of channel, but its corrosion resistance and impermeability always been troubles. After on-the-spot investigation, Xinhai technical personnel added wear-resisting rubber inside tube valve, effectively avoiding the acid resistance, alkali resistance and corrosion resistance. In the operation process, pinch valve can last half a year without replacement, effectively solved the customer problems.
