Cast Iron Check Valve
Product Description The valve disc of the swing check valve is disc shaped and rotating around the seat channel. Because the valve channel is streamlined, the flow resistance is smaller than the lift check valve. It is suitable for a large aperture with low flow velocity and unchangeable flow,...
The disc of the valve is opened by hydraulic pressure difference and its own weight. The valve is suitable for most of the horizontal pipelines in the tank. It automatically prevents the medium from flowing back and protects the upstream equipment. The valve is used in the water and steam medium pipeline with working temperature < 200, and is used to prevent the medium from reversing flow in one way.
