Overview
Pneumatic actuators provide proportional control of steam or hot or cold liquids in HVAC systems by operating V5011, V5013, and VGF valve assemblies. Replacement devices are available for older Honeywell actuators.
Features
Rolling diaphragm for long life and low hysteresis.Easily attached to valve.Can be installed after piping valve.Slide lock feature permits simple engagement to valve stem.Direct- or reverse-action control.Does not include positive positioner.
