3 inch ball valve stainless steel 304 316 cryogenic pneumatic ball
valve
Pneumatic flange ball valve product features:
1. Gear type double piston, large output torque and small
volume.
2. The cylinder is made of customized materials, with light
weight and beautiful appearance.
3. Manual operation mechanism can be installed on the top and
bottom.
4. Rack connection can adjust opening angle and rated flow.
- The actuator can be equipped with electrical signal feedback
instructions and various accessories to realize automatic
operation.
Pneumatic ball valve is mainly used to cut off or connect the
medium in the pipeline, and can also be used for fluid adjustment
and control. Compared with other valves, it has the following
advantages.
1. The fluid resistance is small, and the ball valve is one of
the small fluid resistances in all valves. Even if it is a
reduced-diameter ball valve, the fluid resistance is quite small.
2. Thrust bearings reduce the friction torque of the valve stem,
which can make the valve stem operate smoothly and flexibly for a
long time.
3. The valve seat has good sealing performance. The sealing ring
made of ammonium PTFE and other ammunition materials is easy to
seal, and the valve sealing capacity of the ball valve increases
with the increase of the medium pressure.
4. The valve stem is reliable in sealing. Since the valve stem
only imitates the rotation and does not move up and down, the
packing seal of the valve stem is not easy to break, and the
sealing capacity increases with the pressure of the medium.
5. Due to the good self-lubricating properties of PTFE and other
materials, the friction loss with the ball is small, so the life of
the ball valve is long.
6. The bottom-mounted valve stem and the convex step of the stem
head prevent the stem from spraying out. If the seal of the stem is
damaged due to fire, metal contact can also be formed between the
convex step and the valve body to ensure the sealing of the stem.
7. Anti-static function: Set a spring between the ball, valve
stem, and valve body to discharge static electricity generated
during the switching process.
