are designed to prevent the reverse flow of medium automatically,the valve disc automatically opens under the action of fluid pressure, and the medium flows from the inlet port to the outlet port. When the inlet port pressure is lower than the outlet port pressure, the valve disc will be automatically closed under the fluid pressure difference and dead weight condition,which to prevent the flow back.The valve are widely used in metallurgy, power plants, oil refineries and petrochemical plants and other pipeline systems.
Product Feature
1.Simple structure, Short Face-to-face,reliable operation, fluid resistance less than the lifting check valve.
2.Only applicable to unidirectional medium.
3.The disc of rubber lined swing check valve disc disc is disc-shaped, rotating around the shaft of the seat channel, because the channel in the valve is streamlined, flow resistance is smaller than the lift type check valve, suitable for low flow rate and flow infrequent changes in large diameter conditions, but not suitable for pulsating flow.
4.Using special molding process, the rubber lining in the valve body cavity to avoid the corrosion of weak corrosive media.
