HT7300 Globe Valve For Direct Installation Of High-Pressure Clean Fluid Medium
Product Description
Huatao adopts multi-stage pressure reduction and anti-cavitation measures to greatly extend the service life of the valve. At the same time, this high-pressure valve adopts a snap-in automatic centering valve seat, which is very convenient for disassembly, maintenance and inspection. Based on this, this straight-through high-pressure valve has the advantages of simple structure, easy maintenance, appropriate material selection, reasonable structure, and long service life. It is widely used in straight-through installation situations of high-pressure clean fluid media such as electric power, metallurgy, and chemical industry.
Features
◆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 pressure.
◆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 HUATAO'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 principle.
◆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.
