Pneumatic O-type shut-off ball valve is mainly used to cut off or connect the medium in the pipeline, can also be used for fluid regulation and control, compared with other valves, has the following advantages.


Characteristic


1. Small fluid resistance, ball valve is the lowest of all types of valve fluid resistance, even if the diameter of the ball valve, its fluid resistance is quite small.


2. Thrust bearing reduces the friction torque of the stem, so that the stem can be operated smoothly and flexibly for a long time.


3. Seat sealing performance is good. The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal, and the sealing capacity of the ball valve increases with the increase of medium pressure.


4. Stem sealing is reliable, because the stem only rotates without lifting, the packing seal of the stem is not easy to be destroyed, and the sealing capacity increases with the increase of the pressure of the medium.


5. Because PTFE and other materials have good self-lubrication and little friction loss with the ball, the service life of the ball valve is long.


6. Lower-mounted stem and stem head bump to prevent stem from ejecting, such as fire caused stem seal damage, bump and valve body can also form metal contact to ensure stem seal.


7. Antistatic Function: Springs are arranged between sphere, valve stem and valve body, and the static electricity generated during the switching process can be exported.


Pneumatic O cut off ball valve actuator


Adopt new series GT pneumatic actuator, have double acting type and single acting type (spring reset), gear rack drive, safe and reliable; Large diameter valve adopt series AW pneumatic actuator pull fork drive, reasonable structure, output torque big, double acting type and single acting type.


1, the gear type double piston, the output torque is big, the volume is small.


2. The cylinder is made of aluminum gold material with light weight and beautiful appearance.


3, manual operation mechanism can be installed at the top and bottom.


4. Rack type connection can adjust opening angle and rated flow rate.


5, the actuator can be charged with feedback signals and various accessories to achieve automatic operation.


6. IS05211 standard connection provides convenience for installation and replacement of products.


7, the joint screws at both ends can make the standard product at 0 degree and 90 degrees, with an adjustable range of + 4 degrees. Ensure synchronous accuracy with valves.


The following options can be selected according to different control and requirements:


Cut off accessories: single electronic controlled solenoid valve, double electronic control solenoid valve, limit switch switch.


Adjustable accessories: Electrical positioner, pneumatic positioner and electrical converter.


Air source processing accessories: air filtration pressure reducing valve and gas source processing triplet.


Manual mechanism: HVSD manual operation mechanism.
