Products Description
CA-FIRE Rubber Disc Check Valve
The rubber disc check valve is installed at pump outlets or pipeline connections in water supply and drainage systems to prevent backflow and protect pumps and pipelines from reverse flow and water hammer. It can also be used on bypass pipelines of water storage tanks to stop water from flowing back into the supply system.
The valve features a ductile iron body with a reinforced rubber-coated disc made of a steel core fully bonded with EPDM or NBR rubber, ensuring reliable sealing, corrosion resistance, and long service life. Designed with a full-bore flow passage, it reduces pressure loss and flow resistance. The 45° inclined disc design shortens closing time and effectively minimizes water hammer. The valve is suitable for clean water, wastewater, and certain oil-based media, with a maximum working temperature of 80°C.

Applications & Working Principle
Applications
The rubber disc check valve is widely used in water supply and drainage systems, pump stations, and pipeline networks to prevent backflow and protect pumps from reverse flow and water hammer. It is commonly installed at pump outlets and pipeline connections. The valve is also suitable for bypass pipelines of water storage tanks, as well as industrial piping systems in petrochemical, municipal, and water treatment projects.
Working Principle
The rubber disc check valve operates automatically based on the direction of fluid flow. When the medium flows in the forward direction, the pressure pushes the rubber-coated disc open, allowing smooth passage through the full-bore flow channel. When flow stops or reverses, the disc closes quickly under gravity and back pressure, forming a tight seal against the valve seat. The 45° inclined disc design shortens closing time and helps reduce water hammer impact, ensuring reliable system protection.
