◆A structure with disperse throttling can avoid serious local erosion caused by resistance to flow.
◆A first throttling is carried out by adopting a reducer coupling to set up the resistance (orifice plate
throttling) in valve.
◆A second throttling is carried out by adopting a perforated cage (characteristic throttling) to disperse a
◆A balanced structure fits for a plug with dia. 25mm or above, and a shunting can be realized through
the balance hole after refined calculations.
◆Double seats adopt the design and processing technic from VALCAM's original creation, which realize
a close fitting of seat and plug to ensure a tight closure under pressure differential.
◆A thrid throttling will be carried out through a cage with an anti-cavitation structure as per the multistage
◆Cage guided adopts the dispersal of impact load caused by vibration through a large metal surface to
reduce damage on metal surface and wear from guiding.
◆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 and have along service life.
◆Pressure Rating: ANSI Class600，900，1500，2500
◆Nominal Dia:DN6～200；End Connections: welded, flanged,
◆Working Temperature: -45～+540℃(according to on-site conditions)
Superior to ANSI B16.104 Class IV; Equivalent to ANSI B16.104 Class V.
