PIC Series Pinch Valves - Reliable Sealing & No Downtime

How sleeve valves work?

The automatic elastic deformation valve consists of a valve body and a cylindrical sleeve covered with natural or synthetic rubber. It is normally open.

The valve is closed by applying pressure between the body and the sleeve using a fluid, usually compressed air (which can be replaced by pressurized water). Under the action of this fluid, the sleeve collapses in a preferred direction, achieved by a judicious arrangement of the fabric, thus allowing complete closure.

Advantages of our sleeve valves

• Full-bore design: No pressure losses or risk of obstruction
• Complete closure even in the presence of solid particles, gases, powders, and liquids.
• Long sleeve life: Our sleeves are reinforced with incorporated fabrics and are available in 3 grades
• No risk of leakage into the environment due to the absence of a gland
• Protection of the installation: water hammer is prevented when the valve is closed and opened
• Simple installation

Thanks to their characteristics, Milton Roy elastic deformation sleeve valves have the advantage of being suitable for a wide range of industries and applications: liquids, suspensions, granules, pastes, etc.

• Acids: Hydrochloric, nitric, sulfuric, hydrofluoric, etc.
• Bases: Soda, ammonia, potash, phosphates, sodium bicarbonate, etc.
• Viscous or abrasive liquids: Seawater, wastewater, lime milk, paper pulp, paint, sludge, soot, clay paste, etc.
• Powders: Cement, flour, sand, talc
• Food liquids: Beer, wine, cocoa butter, edible oils, beet juice, milk, sugar, syrups, etc.
• Other fluids: Water treatment reagents, organic solvents, fertilizers, etc.

They are widely used in water treatment plants, cement factories, silos, wineries, and even trains!

How effective is a pinch valve?

• Provide 100% leak-proof sealing.

• Handle abrasive and corrosive fluids without damage.
• Offer full-bore flow, preventing blockages.
• Require minimal maintenance (only the sleeve wears).
• Are energy-efficient, consuming little compressed air.

Milton Roy pinch valves are proven in industries like food processing, wastewater treatment, cement, silica, ceramic, glass, mining, silos, and chemical industry, ensuring safe, reliable, and cost-effective flow control.
