Remark:
1. Torques will increase about 30% if seat material is Reinforced Fiber-Glass PTFE, Carbon-filled PTFE or EK+PTFE or TFM 4215.
2. The torque figures at 5 bar pressure are maximum values to be tested after the valves are placed for 24 hours.
3. For actuator sizing, a safety factor of a minimum of 30% is recommended.
