Recommended operating thrust and torque are the loads required to close the valve with full differential
pressure across the gate. The operator should be sized for these values.
Maximum thrust and torque values are the maximum allowable loads for these valves.
When”Block and Bleed” or “Double Block and Bleed” service is specified, operators should be sized for
these values.
Unless otherwise stated, handwheel rim pull for manual and motor operators shall not exceed 120lbs.
All torque and thrust values are based on maximum working pressure at ambient temperature.
