Multiposition Air Actuator Fittings
The standard air actuator is rated for use at temperatures up to 70°C. Generally speaking, valves which will be in ovens or heated zones require a standoff assembly, which locates the air actuator out of the heated zone and supports both the valve and actuator. A high temperature model permits both valve and actuator to be mounted within an oven (175°C maximum), but it is not recommended for use below 50°C.
The recommended method for implementing a multiposition air actuator is with a single 4-way solenoid. Typical actuation pressure is 40-50 psig, but up to 80 psig may be used without damaging the valve or actuator. Bottled instrument air or nitrogen is recommended. If plant air from compressors must be used, an oil separator and water dryer are required. Multiposition air actuators include a rotary switch which may be connected to a digital readout or to a multiposition control module (MCM) or electric position indicator (EPI). A BCD encoding board is optional.
Please contact OEM for closemount, RAD (right angle), and standoff hardware requirements.
