Product Description
1. Pressure Seal Swing Check Valve adopts rocker swing disc with pressure self sealing bonnet.
2. Forward flow pushes disc open, disc swings back to press against seat for sealing during backflow.
3. Bonnet achieves self sealing by medium pressure, the higher the pressure the tighter the sealing.
4. Full bore flow channel with low flow resistance, suitable for high temperature and high pressure steam and oil pipelines.
5. Only installed on horizontal pipelines, to prevent medium reverse flow.
