Main character
Special throttle capaility
When the valve core on moves when the valve lever promotion function turns on a valve core set of throttle,The fluid first reduces expenses by the cone-shape the vice- valve petal less advanced to reduce expenses to enter the valve seat cavity,Again operates the throttle through the valve core wrap which the hole spot and the valve core nose column surface forms to discharge. In throttle process,The major part pressure adds in the cone-shape reduces expenses on the vice- valve petal,The small partial pressure adds on a valve core set of throttle,The high speed fluid is much more serious than to the spray nozzle attrition the throttle,But wears the cone-shape reduces expenses the vice- valve petal to be advantageous for the replacement.
Double seal
The valve core and the valve seat hard alloy sealed vice- and softly seals vice- between has formed the double nature seal, had guaranteed the valve bore washes out and the zero divulges the request.
The balance design of open and close structure
On the valve core opens has the balancing hole, causes, under the cavity medium to be at the state of equilibrium, enhanced the stability and the reduction which the valve opens opens the resistance.
