1, double seal design (bellows + filler) If bellows failure, stem filler will avoid leakage, and comply with international sealing standards.
2, no fluid loss, reduce energy losses, improve the safety of plant equipment.
3, long service life, reduce maintenance times, reduce operating costs.
4, Rugged bellows seal design, to ensure that the valve stem 0 leakage, provide no maintenance conditions.
5, the gas medium valve seat uses the PTFE soft seal material enhances this valve the seal. 6, high temperature ≤425℃ valve seat using conical hard seal.
To achieve 0 leakage of airtight performance. With the rising cost of labor to reduce the labour force is more and more companies want, there is such a bellows cut-off valve allows workers to switch easier products to use longer life sealing performance better products, there is reason to believe that its prospects will be more and more wide.
