Radius

The RX series valve positioners from Radius come in both pneumatic and electro-pneumatic versions and are supplied ready to direct mount to actuators with the NAMUR type top shaft. They are easy to install and are designed to accommodate individual maintenance or repair.

The electro-pneumatic valve positioner, RX-1000, is for rotary operation of pneumatic actuators using a control system with a signal 4 to 20 mA. It comes standard with manual override.

The RX-500 valve positioners are for rotary operation of pneumatic actuators using a 3-15 PSI control system. It has low air consumption, has fast and accurate response, and is easy to switch from reverse to direct action.
