The rubber disc check valve is designed with a streamlined seal ring to shorten closing time and reduce pressure caused by water hammer. The valve disc is made by pressing acrylonitrile-butadiene rubber and steel plate under high temperature. Built with a body, bonnet, disc, and spring, it offers wash-out resistance, a reliable seal, simple structure, and convenient operation, and is mainly used at the pipe outlet in petroleum, chemical engineering, and other industries.
Product Introduction
The rubber disc swing check valve mainly consists of three main parts: the valve body, the valve cover, and the rubber valve element. The rubber flap is made of steel plate and steel bar, reinforced with nylon fabric, and the outer layer is made of rubber. Under normal service conditions, the valve service life can reach 1,000,000 cycles [reference value]. The valve is designed with a full-flow area, featuring low head loss, no debris accumulation, and gradual maintenance needs, among other benefits.
The valve is mainly used in water supply and drainage systems. It can be installed at the pump outlet to prevent reverse flow and protect the pump from damage caused by water hammer. The valve can also be installed on the bypass pipe of the water intake line to prevent backflow.
Product Features
The Yifa rubber disc swing check valve is mainly used in water supply and drainage systems. It can be installed at the pump outlet to prevent damage to the pump caused by medium backflow. It can also be installed at the outlet of a water discharge pipe to prevent backflow of the medium. The valve has a simple structure, reliable performance, and a long service life. The open-close cycles can be up to more than one million [reference value], making it suitable for sewage applications.
