Operational Lockout
(2)
Available for customer‐supplied padlock to lock the actuator in the spring‐fail position
1. The pressure/temperature limits in this manual should not be exceeded. The current SIL certification for the 2052 actuator is only relevant for the standard temperature ratings shown.
2. Lockout and declutchable handwheel cannot be used together on size 2 and size 3 actuators.
3. Temperature range only applies when using silicone diaphragm material. Silicone diaphragm is not available with the top-mounted handwheel option.
4. Temperature range requires use of stainless steel bolting for yoke and travel stops. Not available with top-mounted handwheel.
