Valve sleeve type drain valve

1.FJ41YFValve sleeve type drain valveThe use of dual seals (hard and soft seals) ensures reliable sealing, and the hard alloy cover can be more resistant to air flow erosion and wear. The dual seal can achieve zero leakage under high-pressure gas medium conditions. The valve has a long service life.
2. The sealing surface of the valve seat adopts a tapered seal, which is beneficial for the valve to clean the dirt attached to the sealing surface.

3. The valve disc of the valve is equipped with a balance hole and a piston type seal, ensuring stable operation under full pressure difference conditions for opening/closing, with light and flexible opening and small opening/closing torque.

4. The packing adopts a V-shaped packing structure with self sealing ability, which does not require adjustment and is extremely lightweight to open and close. There is an auxiliary sealing grease injection structure at the packing box, which ensures reliable sealing performance of the valve packing.
5.Online maintenance can be carried out, and pipelines can replace vulnerable parts such as packing under pressure.
6. A large drain hole is set at the bottom of the valve, which should be opened if necessary to clean the dirt inside the valve.

7. The outer rim of the discharge valve disc is equipped with an O-ring seal, which has a self-cleaning function and sealing during opening/closing, and a throttling and pressure reducing function during discharge.
