Yes. This is one of our core strengths. We offer a wide range of elastomer sleeve materials, including Natural Rubber (for abrasion), EPDM (for chemicals), Neoprene, and food-grade options. Contact our technical team with your media details, and we will recommend the optimal material.

What is your Minimum Order Quantity (MOQ)?

We support both large-scale project orders and smaller stock orders for distributors. Our MOQ is flexible. Please contact our sales team with your requirements for a specific quotation.

What are the advantages of pinch valves over traditional valve types?

Benefits include low maintenance, a compact design, quick operation, self-cleaning, tight shutoff, and minimal turbulence. Only the rubber sleeve needs periodic replacement.

What is the typical operating temperature and pressure range for pinch valves?

Standard models operate up to 250°F, with special versions for temperatures from -100°F to 550°F. Pressure ratings depend on valve size, ranging from 100 psig for 1-inch valves to 15 psig for 12-inch ones, with special models reaching 300 psig.

What is the difference between a pinch valve and a diaphragm valve?

Pinch valves use flexible sleeves for full-bore closure, while diaphragm valves use a flexible membrane against a weir. Pinch valves handle more abrasive media and offer better self-cleaning.

How long does a pinch valve sleeve last?

Typically 1-3 years depending on application, media type, cycling frequency, and operating conditions. Abrasive materials reduce lifespan while clean media extends it.

Can pinch valves handle vacuum?

Yes, with proper reinforced sleeves and body design. Standard pinch valves handle up to -0.5 bar vacuum, while specialized designs can manage full vacuum.

What is the maximum pressure rating for pinch valves?

Standard pinch valves operate up to 10 bar pressure. Size affects rating - smaller valves handle higher pressures (up to 20 bar) while larger ones typically max at 6 bar.

Are pinch valves suitable for food applications?

Yes, with FDA-approved sleeve materials like white natural rubber or food-grade EPDM, pinch valves are widely used in food, beverage, and dairy processing.
