◆The improvement of anti-cavitation is carried out by using the principle of a multistage plug for
◆ A structure with disperse throttling can avoid serious local erosion caused by resistance to flow.
◆Trim is made from anti-erosion and anti-cavitation materials with good hardness and tenacity by
special treatment, which increases the stiffness of moving part to eliminate cracking. Plug, seat and
surface guided all of them gotten unique finish and hardness pairing, when closed, the leakage is
minimal, and have a long service life.
