“EN Series” Pinch Valve is an enclosed body of Ductile Iron, and can be hand wheel or actuator operated. It is extremely reliable when it matters most, totally maintenance-free, full bore, full flow in design. These pinch valves are ideal for tough slurries, highly abrasive, and corrosive chemical applications.
The heart of the “EN Series” Pinch Valve has a one piece, rubber sleeve, engineered for each application, with a centerline closure of two mechanical pinch bars on the sleeve, to ensure bubble tight closure.These sleeves are available in a wide variety of elastomers suitable for all applications. With excellent control properties, this pinch valve can be used as a ON-OFF or throttling control service. Reduced port, conical port and double wall sleeves are available, in a wide variety of trims for any application.
“EN Series” Pinch Valve are fully flanged and can be drilled to suit all standard drilling patterns(ANSI, BS, TABLE D/E etc)
• Enclosed ductile iron body
• Dual pinch mechanism
• Bubble-Tight shut-off even on trapped solids
• 100% Full bore full flow
• No Packing less maintenance
• Fast and East field replaceable sleeve

Rubber Duckbill Check Valves and Inline Rubber Check Valves are an exceptionally reliable and cost effective method to control back pressures in sewage treatment plants. Other common applications are stormwater outfall, effluent discharge, flood control, wet wells. These valves are fully passive flow devices, which require absolutely no maintenance whatsoever, no source of power or manual operating assistance, and are an excellent alternative to conventional flap gate valves and other check valves.
The flexible Rubber Duckbill Valve is normally closed but will open with very minimal head pressure, always providing maximum flow with minimal pressure drop across the valve. Conventional Flap-Gate Check valves, and other check valves are mechanical and have metal components that are commonly know to malfunction, rust, and seize. Rubber Duckbill Check Valves will even handle large obstructions without jamming or binding, and guarantee trouble free back flow prevention, and can even seal around trapped or suspended solids with minimum back pressure. The finest of engineering elastomers are used, and the outer layers, are designed to repel marine organisms.
