Specification

DESIGN

The electro-pneumatic positioner DA is used for operation of pneumatic linear valve actuators by means of electrical controller or control system with an analog output signal of DC 4 - 20mA or split ranges.

No resonance 5 - 200Hz.Auto/Manual switch.

Simple zero and span adjustment. 

Forward and reverse, single acting and double acting directly facilitate the conversion.

Internal feedback signal is available as an option (Weather proof only).

Small implementing agencies can prevent vibration through the narrow orifice locator.

RA v.s. DA action and 1/2 split range setting by simple adjustment.
