V100E Fail Freeze Positioner

Brand: Valve Accessories & Controls

By adding the Fail Freeze module to the base pneumatic valve positioner, you convert this product to an electronic “fail in place” positioner. While under normal function, this unit operates as a normal 4-20 mA positioner.

However, should you have a power interruption, the special unit will “lock” the actuator in place and “fail freeze” the package at its last signal position. Once power is restored, the unit will regain its original normal operation.
