■ J19H pressure gauge globe valve product overview :
The opening and closing part of "J19H pressure gauge stop valve " is a plug-shaped valve flap with a flat or tapered surface. The valve flap moves linearly along the centerline of the fluid. The movement form of the valve stem has a lifting rod type (the valve stem is lifted and lowered, the hand wheel does not move up and down ) , and there are also lifting Rotating rod (hand wheel and stem rotation movements, nut located in the body).

J19H pressure gauge stop valve " only applies to full opening and full closing, no Allow adjustment and throttling. "J19H pressure gauge shut-off valve " is a forced-sealed valve, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface to not leakage. When the medium enters the valve from below the valve flap, the resistance to be overcome by the operating force is the friction between the stem and the packing and the pressure from the medium. The generated thrust, the force of the "J19H pressure gauge stop valve " is greater than the force of the "J19H pressure gauge stop valve " , so the diameter of the valve stem is large, otherwise the valve stem top bend failure will occur.
