1.Anti-corrosion,durable and long life-span 2.High precision of regulating 3.API607 and ISO9001-2000 4.Grade A2 Manufactur
Product characteristics1) Compact structure, small cubage, light weight, long lifespan and convenient to be installed andmaintained;2) Eccentric structure can reduce the wear of seat and expand the lifespan.3) Guide vane in the end of core makes for the stable flow of fluids.4) Seat and core closely contact with each other which can effectively cut off media when fully closed.5) Hard sealing core and seat are overlaid with high rigidity alloy which can improve the wear resistantand corrosion resistant.6) Leakage of hard sealing can reach class VI.7) Applicable to the control and shut-off of media with high viscosity, fibre and granule.
