Product Features

• Full-bore design - no flow restriction;
• Center-line closing - extends bushing service life;
• Only the bushing contacts the medium - only one wear part exists;
• Self-cleaning function - no jamming;
• Multiple bushing material options - meet the requirements of different media;
• Robust design - extends the interval between maintenance services;
• The rubber bushing, the "core component" of the pinch valve, is a part of the valve that comes into contact with the process medium;
• Customized bushing design: the most suitable bushing structure is selected according to the customer's application conditions;
• When the valve reaches the end of its service life, a "nearly new" pinch valve can be obtained after replacing the bushing.

Structural Features

• Fully Open: The full-bore elastic bushing of the pinch valve has no gaps or dead corners;
• Closing Process: Center-line closing - this feature avoids turbulence and wear inside the bushing. The bushing forms a smooth, closed Venturi tube and achieves self-cleaning with each operation;
• Fully Closed: The pinch valve ensures bidirectional zero-leakage shut-off when fully closed, adopting an inherently safe design that requires no maintenance for seals.

Materials

• Valve Body Material: Carbon Steel, Ductile Iron, SS304, or others
• Bushing Material: NR, EPDM, NBR, etc.
• Valve Stem Material: SS304
• Fastener Material: SS201, 304, 316
