It is equipped with a drive unit that can perform two-stage opening and closing operations that can control the flow rate for one-stage opening and closing operations and antistatic measures (initial flow velocity of 1 m / s or less). This drive unit can be configured to support either electric or pneumatic remote control.
In addition, a single-acting drive unit with a structure that automatically shuts off the ball valve when the power supply and operating air source are lost in the event of a disaster is prepared.
● 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.
