Pneumatic Valve Positioner

Non-standard controller output

The positioner is used to operate a valve with 3-15 psi spring range when controller signal is other than 3 –15 psi.

Non-standard actuator spring range

The positioner is used to operate valves having non standard actuator spring ranges by controllers having the standard 3-15 psi signal pressure.

Remote valve location

When air operated control valves are located far from control instrument, positioners will reduce lag, thereby speeding up valve operation.

Split range

Some processes require the dual or sequential operation of two to three control valves by a single controller with a 3-15 psi output signal range.

Improves all performance

When process lags necessitate the use of wide controller proportional band, the positioner provides an exact means of making the control valve responsive to infinitely small changes in controller output pressure.
