Product description
HTN by warm water regulating valve of a multi-stage anti-cavitation valve,, also called high differential pressure regulating valve, is a novel structure of the patented products in china. The valve is mainly used for power generation of 600000 ≤ kW unit plant, control of boiler main steam and hot steam spray desuperheating water, can also be used in petroleum, chemical industry to control the flow of high pressure liquid.
1, the fluid level blood pressure, fluid changing direction, increase the flow resistance, control of fluid velocity, reduce cavitation damage, 15MPa allows the valve pressure difference.
2, the multistage throttle, the throttle the flow of level 4, small flow 5 throttle, to reduce the flow erosion.
To separate the 3, cutting surface and the sealing surface, the valve spool, spool cover surface hardening, the hardness of HRC70 or so, closed tight, long life.
4, the spool surface having large gaps, fluid containing 2~3mm welding slag and other solid particles, the spool will not get stuck, flexible movement.
5, flow regulation characteristics, the adjustment range (60~70%).
