Mine dedicated high-performance pressure reducing valve cnjianyafa 



 Mine dedicated high performance the relief valve http://www.cnjianyafa.com/jianyafa/kgy.html is mine special working conditions combined with foreign technology developed special special valve is a pilot type valve, mainly by The two parts of the main valve and pilot valve. The main valve by valve, valve seat, the main valve plate, piston, cylinder liner, springs, pressure gauge, switch valves and other parts, pilot valve from the valve seat, the valve diaphragm, spring component parts. This product is done a lot on the basis of the valve of the improvements, such as increased piston area, to change the the throttle structure and sealing form, thereby improving the sensitivity, flow, life and other performance.
