Times, and then through the hose connection to the container with water detection, about cm depth, min or so.
all welded ball pneumatic valve strength test is the water used as dielectric strength test, need the ball joints welded high pressure duh cap on both ends of the pneumatic valve, the ball of the pneumatic valve ball in the open position, using pneumatic valve pressure test on the sleeves on both sides to infuse water welding pneumatic ball valve and the pressure to the welding ball nominal pressure of the pneumatic valve regulation. Times, the holding min, if not then no leakage of the medium leaking as normal.
