Notes:
1. Torque values apply to clean fluid at ambient temperatures.
2. Other applications may affect above listed values.
3. Consult factory for torque values for seat materials other than those listed.
4. Handles are not recommended for valves larger than 6". Gear operators or other actuators are recommended.
5. This chart is to be used as a guide only. Some variation is possible based on application.
