A pneumatic pinch valve closes by compressing an elastomer sleeve. With no rigid internal obstruction, it can be a practical choice for media that would clog, abrade or build up in conventional valve designs.
Typical applications

Five inputs for correct selection
- Medium: particle size, concentration, abrasiveness and chemical composition.
- Operating conditions: line pressure, temperature, flow direction and required cycle frequency.
- Sleeve material: choose after checking abrasion, temperature and chemical compatibility.
- Connection and size: flange standard, DN/NPS size and installation space.
- Control method: available instrument air pressure, solenoid valve, position feedback and fail position.
Why sleeve specification is critical
The sleeve is the main wetted and wear component. Correct material selection supports reliable closing and service life; incorrect selection can result in swelling, premature wear or leakage. Provide the full medium details before confirming the sleeve.
