The Benefits of Using manual pinch valve

The pinch valve is the simplest valve design on the market, and has many benefits over conventional type valves. Most other valve types are unable to handle fluids with high concentrations of solids due to the particles often jamming the metal parts and clogging up the valve. Pinch Valves are the complete solution for handling almost every media in even the most severe application specifications, with no metal or mechanical parts.

The flexible elastomer sleeve inside the Pinch Valve, which has been specially designed, forms an effective seal with a tight shutoff around trapped particles. In some applications, particles can become trapped in the seal of the disc or ball in other conventional valves such as ball valves or butterfly valves, resulting in the product not shutting off fully.

Rubber liners inside a Pinch Valve come in a range of different qualities of rubber, making various areas of application, operating temperatures and lasting properties possible. The grade of the rubber is crucial to the life time and anti-abrasion characteristics of the Pinch Valve. Depending on the elastomer used, the pinch valve can be limited in operating temperature and pressure.

In balance, the Pinch Valve advantages far outweigh the disadvantages:

The sleeve within the manual and control Pinch Valve is precisely maneuvered by an internal mechanism paired with an actuator of your choosing. This mechanism typically features one or two horizontally placed pinch bars above and below the sleeve, securely guided by two side rods. These manual and control Pinch Valves are versatile, being compatible with a variety of actuators.

When activated, the actuator causes the pinch bar(s) to pinch the sleeve centrally depending on its size, thereby creating an airtight seal to control the product flow. Additionally, the direct connection between the sleeve and the pinch bar(s) ensures that the sleeve is optimally opened to allow full passage. The maximum operating pressure for these valves can range between 3 and 40 Bar, based on the type and nominal size.
