â–  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.

[Throttle cut-off vent valve] [Features]

1.
This valve is a new type of throttling, cut-off and venting products. The valve adopts the cage-shaped fan army throttling, has multi-stage throttling effect, obvious throttling effect, reliable sealing, convenient operation and maintenance, etc.
2
, the valve uses double seal (hard, soft seal) to make the seal reliable, the hard alloy cover can be more resistant to airflow and wear, and the double seal can achieve zero leakage under high pressure gas medium conditions. Long valve life
3.
The sealing surface of the valve seat is tapered, which helps the valve to clean the dirt attached to the sealing surface.
4. The
balance valve and the piston seal are arranged on the valve flap of the valve to ensure stable operation under the condition of open / close full differential pressure. The opening is light and flexible, and the opening and closing torque is small.
5.
Throttle cut-off venting valve and double-acting throttle valve have both throttling and cut-off (zero leakage of seal). The throttling part is separated from the sealing surface to reduce the scouring of the airflow to the seal.
6.
Double-acting throttle stop valve also has multi-stage throttling function, large throttling pressure difference, and can be applied to throttling and cutoff under high pressure.
7,
a V-shaped packing packing structure with self-sealing capability, without adjustment, the opening and closing very lightweight. An auxiliary sealing grease injection structure is provided at the stuffing box to make the valve packing sealing performance reliable.
8.
The valve can be repaired online, and the pipeline can be replaced with a series of wearing parts such as packing under pressure.
9.
The valve has a large drain hole at the bottom of the valve. If necessary, open it to clean the dirt inside the valve.
