A wear-resistant pinch valve with excellent corrosion resistance and very strong sealing performance. 【Processing capacity】: 1.6MPa/cm² 【Scope of application】: The wear-resistant pinch valve is suitable for various abrasive and non-abrasive pipeline transportation, uniform addition of chemicals in chemical industry and mine, and uniform ore drawing in mine beneficiation process.
Xinhai wear-resistant valve products are generally manual, and can be made into electric and pneumatic according to the requirements of users;
Full section with almost no flow resistance;
Replaceable bushing: Simply replace the bushing and the valve is in good condition;
High sealing: use a bushing with good elasticity to seal solid particles;
Wear resistance: The super wear-resistant rubber produced by the process of "using liquid phase nano-formulation, high-frequency curing at room temperature" has a life span of 10-15 times that of ordinary rubber and 3-6 times that of polyurethane;
Anti-fatigue: The rubber has strong anti-fatigue ability and can be used for a longer time, which is "worldly difference" compared with the anti-fatigue of ordinary rubbe
The mechanical part is protected: only the rubber bush contacts the processing material, and the mechanical part is protected;
Xinhai pinch valves are inexpensive and easy to replace.
The wear-resistant pinch valve is composed of upper grip, valve body, rubber spool and lower grip.
The working principle of the pinch valve is driven by an electromagnetic solenoid, which is controlled to open and close by squeezing or loosening the hose. The medium only passes through the hose, and other parts in the valve body should not be in contact with chemically corrosive medium, and only the hose needs to be replaced. This means that the pinch valve is more economical than other types of solenoid valves.

A concentrator in Indonesia chose a pinch valve to control the opening and closing of the channel, but the corrosiveness and airtightness have always plagued the plant. Xinhai Mining staff added wear-resistant rubber to the inside of the pinch valve through on-the-spot investigation, which effectively achieved acid resistance, alkali resistance and corrosion resistance. During the use of this concentrator, the pinch valve can not be replaced within half a year, which effectively solves the customer's problem.
