Torque Curves
The working torque of ball valves depends on the pressure and ball seat sealing material. In the diagram, the working medium is oil, the seal is POM and (supposing water*1.2, air*1.4 and granular powder*1.6) actuator torque = 1.2*Torque (where: 1.2 is the safety factor).

Ball Valves with Lock
BKH series ball valves offered by EAGLE can all be provided with a structure for lock, thereby protecting the open/closed status of critical ball valves. The lock needs to be separately purchased by customers.

Please add “AV” to the end of the ordering number when placing an order, for example: BKH-G1-25-4425-AV.
