    Torque Curves
    The working torque of ball valve depends on pressure and ball seat sealing material. For the diagram below, working medium is water, and seal material is POM. Torque is 1.4 times that of POM supposing sealing material is PEEK, 0.8 times for oil, 1.3 times for air, and 1.4 times for granular powder. Actuator torque = 1.2*Torque (1.2: safety factor).



     

     

    Ball Valves with Lock
    EAGLE's BKH series ball valves can provide a locking hole to protect the open/closed status of critical ball valves. The lock needs to be purchased by customers separately.
    Please add "Av" to the end of the ordering number placing an order with locking structure, for example: BKH-G1-25-4425-AV

Torque Curves
The working torque of ball valve depends on pressure and ball seat sealing material. For the diagram below, working medium is water, and seal material is POM. Torque is 1.4 times that of POM supposing sealing material is PEEK, 0.8 times for oil, 1.3 times for air, and 1.4 times for granular powder. Actuator torque = 1.2*Torque (1.2: safety factor).



 

 

Ball Valves with Lock
EAGLE's BKH series ball valves can provide a locking hole to protect the open/closed status of critical ball valves. The lock needs to be purchased by customers separately.
Please add "Av" to the end of the ordering number placing an order with locking structure, for example: BKH-G1-25-4425-AV
