    Features & Benefits

    Seallon`s SJ41 pinch valves are designed for shut off and control applications, such as abrasive or corrosive pulps, slurries, powders or granular substances. The valve is full bore with no flow restrictions, during closing two pinch bars squeeze the rubber sleeve shut on the center line. Bubble tight shut-off is provided even if solids have built up on the sleeve wall.

    Flanged Pinch Valve SJ41

    Yoke with platform under actuator, can be customized by ISO5210, GOST55510 or other standards.

    The stem is often made from stainless steel or other high-strength materials to ensure durability and resistance to corrosion.

    The rubber sleeve is made from materials such as natural rubber, EPDM, nitrile, or polyurethane, depending on the chemical compatibility and temperature requirements. It is flexible, resistant to abrasion, and offers good sealing properties. It is the key sealing element in a pinch valve. When the valve is closed, the sleeve is pinched to completely obstruct the flow of the media. It is responsible for providing a tight, leak-free seal, effectively isolating the flow in the pipeline.

    The pinch mechanism usually consists of a set of rollers or plates, typically made of stainless steel or high-strength alloys, that compress the rubber sleeve. It is responsible for pinching the rubber sleeve to block or regulate the flow of the media. It can be operated manually, pneumatically, or hydraulically to adjust the pressure on the rubber sleeve, opening or closing the valve as needed.

    The valve body is typically made from materials such as cast iron, steel, or aluminium, depending on the application and fluid being controlled. It is designed to withstand high pressure and provide a strong, durable structure.
