The Pinch Valve is a robust solution designed to replace traditional butterfly, gate, and ball valves in demanding environments. It is particularly effective for handling water, sewage, oil, slurry, and acidic or alkaline solutions. Due to its anti-abrasive and corrosion-resistant properties, it is widely utilized in thermal power plants and waste-flushing systems in steel mills.

Frequently Asked Questions
What are the primary applications for pinch valves?
Pinch valves are ideal for abrasive and corrosive slurries, powders, and granular substances. They are widely used in mining, wastewater treatment, and chemical processing.
How does the "Full Diameter" design benefit the flow?
The full-bore design ensures that when the valve is fully open, the flow path is a straight cylinder. This minimizes pressure drops, prevents turbulence, and eliminates the risk of cavitation.
Are these valves suitable for scaling media?
Yes. The flexible nature of the rubber sleeve causes any built-up scale to crack and flake off during the opening and closing cycle, making the valve self-cleaning.
What maintenance is required for a manual pinch valve?
Maintenance is minimal because only the rubber sleeve comes into contact with the medium. There are no seals or packing to replace; you only need to inspect the sleeve for wear over time.
Can the sleeve material be customized?
Absolutely. We offer various sleeve materials including Natural Rubber, EPDM, NBR, and FPM to ensure compatibility with different chemical and temperature requirements.
What standards do your valves comply with?
Our valves are designed and tested according to international standards such as ANSI, DIN, JIS, and GB, ensuring global compatibility and safety.
