An Automatic ball valve dedicated to two-stage opening and closing operation that uses a double torque cylinder. It does not require a positioner that is normally used for two-stage opening and closing operations. In addition, once the valve opening is adjusted, the structure is such that stable operation can always be obtained repeatedly.
● The ball valve body has a fire-safe mechanism (confirm to API607A-4). * 1
● The ball valve body has a mechanism to prevent static electricity from being charged due to sliding friction.
● The drive mounting flange of the ball valve body complies with ISO5211. * 2
* 1. A mechanism that minimizes leakage even if the seat, gasket, etc. that make up the ball valve body disappears in the event of a fire.
* 2. A structure that can be automated (mounting the drive unit) without loosening the gland packing.
Note: The above contents are not supported by the ball valve of the cast iron body.
