Features:
- The channel is smooth and the flow coefficient is small. The sealing surface is less susceptible to medium erosion and erosion.
- The sealing surface is made of alloy steel or hard alloy, with good wear and scratch resistance.
- Adopting flexible graphite filler, reliable sealing, and easy and flexible operation.
- The flow direction of the medium is unrestricted, does not disturb flow, and does not reduce pressure.
- Filler replacement and maintenance can be carried out in an online shutdown state, which is convenient and fast without affecting system operation.
