Product Feature：
The bottom mounted valve stem and the stem of the valve stem prevent the valve stem from being sprayed out.
If the valve stem seal is broken due to fire, metal contact can be formed between the convex step and the valve body to ensure the valve stem is sealed.
Due to the strong anti-static function, a spring is arranged between the ball, which can discharge the static electricity generated by the switching process.
Product Description:
This double acting pneumatic rotary actuator is equipped with small fluid resistance, which is the one with the least fluid resistance, even for the reduced diameter ball valve. In addition, the thrust bearing reduces the friction torque of the valve stem, thus making the valve stem long-term have a balanced and flexible. operation. Compared with ordinary actuator on the market, this double acting pneumatic rotary actuator has excellent seat sealing performance, and the structure is easy to seal. What's more, the valve stem only rotates without lifting movement in order to make the valve stem seal reliable. Since the material has good self-lubricating property, the friction loss with the sphere is small, and the service life is large.
