UP-2 - Analog Valve Positioner
Heavy-duty analogue positioner for precise valve control in linear and rotary actuators.
Provides stable and precise valve positioning with a balanced-forces design for consistent air distribution.
Offers flexible installation with compatibility for both linear and rotary actuators and optional bypass functionality.
Ensures durability in harsh conditions with a heavy-duty metallic housing, IP65 protection, and explosion-proof options.
Features
The UP-2 is a robust analogue positioner available in pneumatic and electro-pneumatic versions. Designed for automated valve systems in oil and gas, refining, chemical, power, and metal industries, it operates with a 3-15 psi pneumatic signal or a 4-20 mA electro-pneumatic signal. The positioner utilises a balanced-forces principle for accurate air distribution and supports both single and double-acting actuators. It features an integrated bypass valve for action inversion without tubing changes and accommodates linear and rotary actuators. With a durable metallic case, IP65 protection, and options for explosion-proof configurations, the UP-2 ensures reliable performance in demanding environments.
