Zoning Control Systems

The PN series pneumatic actuator has an anodized aluminum body and meets international ISO and NAMUR standards for ease in mounting to ISO valves. Spring return actuators are air to open, spring to fail close and are sized for 80 PSI air supply. Standard actuators are rated to 180°F with options for high temperature Viton seals.

The PN series pneumatic actuator has an anodized aluminum body and meets international ISO and NAMUR standards for ease in mounting to ISO valves. Double acting actuators are air to open, air to close and are sized for 80 PSI air supply. Standard actuators are rated to 180°F with options for high temperature Viton seals.

Features: 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 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 Actuator Force : Low 1-3/8" For Valves with Bonnet Size

The Honeywell M9185D1004, from their Series 90 Modutrol line, is a spring return modulating proportional control motors used with controllers that provide a Series 90 output to operate dampers or valves. Integral junction box provides NEMA 3 weather protection if motor is mounted in the upright position. Integral spring return in the event of power failure. Motor and circuitry operate from 24 Vac. Quick-connect terminals are standard; screw terminal adapter is available. Adapter bracket for matching shaft height of older motors is available. Motors have field adjustable stroke (90 to 160 ...
