Main performance and zero components: parts name material body, limit pig iron, stainless steel, stainless steel, tin bronze, tin bronze piston alloy aluminum nitrile rubber, epdm rubber gasket Marine valve o-rings silicone rubber, epdm, main technical performance, work pressure, mpa) 1. 0 to 1. 6 strength try ( mpa) 1. 5. 2. 4 tightly closed to try ( mpa) 1. 1 1. 76 office temperature ( ℃) 80, 150 or less use or less industrial and living water supply, air conditioning, heating, and fire fighting system. Since the size of the cutting plane or surface on both ends of the piston is different due to the pressure difference changes after the valve pressure, is also in the pipeline pressure thing, plane at the ends of the piston and the size of the object surface than constitutes the valve before and after the valve pressure ratio. Q: proportional reducing pressure valve products recommend: a: product introduce: when using the hydraulic principle of stem, lower stress ratio right has simple structure and large flow passage is dynamic pressure reduction, and reduction of static pressure low operation safe and secure no noise, no shock, to reduce water hammer and try our best to take care of pipeline installation low low is suitable for use in arbitrary Angle light weight, large and small, convenient installation and maintenance of office principle: under the effect of inlet pressure p1, floating piston is pushed open, through the medium. No matter how about before the valve pressure changes, after the valve static pressure and dynamic pressure ratio can be reduced to the corresponding pressure value. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
