This innovation product specially for high pressure workplace design For the safe consideration and the convenience. The characteristics is the easy operation and safe under the high pressure condition transfer to be the non pressure condition. ( the safety valve is the necessary equipment under the high pressure operation.)

一、Connection
STEP 1.Meets backward the outer ring, inserts the male plug
STEP 2.Skid the valve to push to the male plug, this for circuit condition
STEP 3. skid the valve to revolve 90 degrees according to the counter-clockwise, this for circuit and previous (Lock) condition
二、Separation step
STEP 1.Skid the valve to be obedient the clockwise to revolve 90 degrees, this is the (Unlock) condition for the circuit.
STEP 2.Skid the valve to pull back the original position, this time will be the close up condition, and releases male inserts the head end memory the remnant pressure
STEP 3. Pulls and takes out the male plug backward the outer ring.
