XL & XL90

XL & XL90

The Valtek XL Series (XL and XL90), two-stage positioners offer fast and sensitive dynamic response characteristics to meet extremely demanding control objectives. The positioners are available with either an electro-pneumatic (I/P) transducer module for milliamp current control signals or a pneumatic module for aircontrol signals. Designed for high performance, these positioners are field reversible and ruggedly built for reliability in severe industrial environments.

Designed for high performance, these positioners are field reversible and ruggedly built for reliability in severe industrial environments

Calibration is easy due to minimal interaction between zero and span, other positioner adjustments are enclosed for protection to discourage tampering

Usable with either single or double-acting actuators (both linear and rotary) makes the XL Series positioners versatile

XL Series positioners are designed with a high natural frequency coupled with pneumatic damping – unaffected by vibrations with acceleration up to 2 g's and frequencies to 500 Hz

Action can be reversed in the field on linear valves by simply turning the cam over, reversing anti-backlash spring and changing output tubing

The XL90 has positioner feedback options with local visual dome indicator, limit switches, and analog position transmitter

The XL Series positioners with the NT 3000 I/P or the pneumatic module are designed to withstand 150 psi at all ports and are relatively insensitive to supply pressure fluctuation
