Valve Control

Intrinsically Safe
Single & Double acting

D3 is a digital positioner where high air delivery capacity is combined with low air consumption. It suits both linear and rotary actuators, single or double acting. Five keys and a large graphic display make D3 simple to configure and adjust. The pneumatic relay consists of piezo electric valves and is made of plastic to offer high corrosion resistance. An easily accessible built in replaceable filter is provided to offer durability together with a sealed of compartment for the terminals.

Communication is possible via HART, Profibus PA and Foundation Fieldbus.

D3 offers a wide range of special versions:
- Fail in last position upon loss of input signal
- Remote mounted
- 270 degree rotation
