ZSHO pneumatic O-type cut-off ball valve（Description）

ZSHO pneumatic O-type cutting ball valve pneumatic actuator adopts AT/GT series pneumatic actuator, with double action and single action type (spring reset), using rack and pinion structure transmission, the performance is more safe and reliable; Large caliber valve adopts AW series pneumatic actuator, fork structure transmission, reasonable structure, high output torque.

ZSHO PNEUMATIC O-type BALL valve has one second time to cut off the ball valve, with explosion-proof device, can be cut off by gas. Is composed of ball valve and single action piston pneumatic actuator, suitable for natural gas, oil, chemical, metallurgy, paper electric office, mining, printing and dyeing, biopharmaceutical, daily chemical, food and beverage, water treatment and air treatment and other industries of fluid cutting control, with automatic pneumatic instrument supporting use.

Operating principle

ZSHO pneumatic O-type cut-off ball valve is composed of valve body, ball, valve shaft, sealing ring, packing, pressure plate and other parts. The actuator is composed of air, piston, gear type, output shaft, cylinder head, bearing, guide ring, piston bearing bush, adjustment bolt, “O” ring and other main parts. The actuator is connected to the valve with a connecting shaft. After the input pressure in the cylinder, it acts on the piston to produce a certain thrust, so that the gear type output is driven by the piston, the gear output shaft is rotated, and the valve shaft is rotated, so that the ball valve ball rotates in the valve, and the circulation area of the valve is changed to achieve the purpose of changing the medium flow through the valve.

Product features

1. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.
2. the valve seat sealing performance is good, using PTFE and other elastic materials made of the sealing ring.
3. Anti-static function: spring is set between the ball, valve stem and valve body, which can export the static electricity generated in the switching process.
4. The valve stem seal is reliable, because the valve stem only for rotating movement and do not do lifting movement, the valve stem packing seal is not easy to destroy.
5. Due to the PTFE and other materials have self-lubricating, friction loss with the ball is small, so the service life of the ball valve is long.
6. Fast cutting speed, with one second time cutting ability, and good sealing performance, can be equipped with explosion-proof device, can be cut off by gas pipeline.
