High reliability
and precision control is no longer tied to big size and high cost. The MPA
series of electric valve actuators provides precise valve positioning in a
compact, simple to install package. Simple on/off control or incremental
(proportional) control is possible. TTL inputs for 2, 3 or 4-way ball
valve control with position feedback. Serial (RS485) or analog (1 - 5V, 4
- 20mA) inputs for proportional control of needle valves. Field selectable
for operation on 12/24 VAC/VDC.
