Terms and definition in the solenoid
¤ Norminal Pressure:the design of valves are same with the national standard and max pressure is same with JB/7352-94 work test & model test.(standardof works test is 1.1 multiple of marked noaminal pressure,sealing test s multiple of norminal pressure)
¤ Working Pressure(pressure difference):pressure diffferencebetween inlet and outlet.
¤ Directing valve:the open or close of the valve is directly driven by electromagnetic force form the solenoid coil.
