Product Description

The Yueda wafer check valve is a compact, spring or flap assisted non-return valve designed to be clamped between two pipe flanges. Its short face-to-face length saves space and weight in pump discharge lines, water treatment plants and building services. The disc closes quickly under spring action, greatly reducing water hammer and preventing back-flow damage to pumps and system components. All wetted parts are manufactured from wear-resistant materials and every valve is pressure tested before shipment.

Key Features & Advantages

• Ultra-short wafer body — light weight and easy installation between flanges
• Spring-assisted fast closure minimizes water hammer and slam
• Low cracking pressure, suitable for low-head pumping systems
• Ductile iron body with epoxy coating; stainless steel disc and spring
• Universal face-to-face dimensions suitable for DIN, ANSI and BS flanges
• 100% shell and seat pressure tested before delivery

Applications

The Wafer Check Valve is widely applied in municipal water supply and drainage networks, water treatment plants, petrochemical and coal-chemical plants, power stations, heating and gas supply systems, HVAC and building services, sewage renovation projects and waste recycling integrated systems. It is also suited to demanding sectors such as floating production storage units, onshore exploration & production, deep-sea extraction, LNG terminals, oil & gas pipeline transmission, and loading & storage systems.

Quality & Certification

Every valve is manufactured under our ISO 9001:2015 quality management system. Products carry UK WRAS hygiene approval and European EN1074 certification, and all processes — casting, machining, spraying, assembly, testing, inspection and packaging — are controlled and traceable. Custom materials, pressure classes and actuation packages are available on request.
