Application:
Sleeve soft sealing plug valves suitable for nominal pressure CLASS150 ~ CLASS900, working temperature -29 ℃ ~ 180 ℃ oil, chemical, pharmaceutical, fertilizer, power industries and so on.
Structural features:
1 set of soft sealing plug card products reasonable structure, reliable sealing, excellent performance and beautiful shape.
2, it is through the ring seal around the sealing surface to achieve. Unique 360 ?metal lips protection fixed ring.
3, soft sealing plug valve sleeve cavity to the medium did not accumulate.
4, the metal lips on cocks turn to provide self-cleaning effect, suitable for viscous and easy scaling condition.
5, soft sealing ring plug flow in both directions, using the installation more convenient.
6, part material and flange dimensions can be a reasonable option based on actual working conditions or the user requests, to meet a variety of engineering needs.
