Honeywell Pneumatic Actuators
Honeywell Light Duty Damper Actuators
Used for pneumatic proportional control of variable volume terminal units and small dampers. Available in various operating ranges for either individual or sequence operation with other actuators.
Stroke: 3" Connection: 1/4" barb Force: 36 in./lb.
Honeywell Medium Duty Damper Actuators
Used for pneumatic proportional control of dampers and high velocity mixing box air valves. They are available in various operating ranges for either independent operation or sequence operation with other actuators.
Honeywell Heavy Duty Damper Actuators
Used for proportional control of medium- to large-size dampers in HVAC systems. The MP918 A & B are rolling diaphragm, piston-type actuators. The MP918A has a positive positioner.
Honeywell MP920B Pneumatic Damper Actuator
Provides proportional control of large dampers in HVAC systems or inlet vanes on a VAV fan. Positive positioner available separately.
Honeywell Pneumatic Unit Ventilator Damper Actuator
Used to control the damper on unit ventilators. May be adapted to various unit ventilator control cycles.
Damper Size: 2.7 sq. ft. Stroke: 2-1/8" to 2-1/2"
Honeywell Pneumatic Variable Volume (VAV) Damper Actuator
Provides proportional control of variable volume dampers in small high velocity mixing boxes.

STILL HAVE GOOD 'OL DEPENDABLE PNEUMATIC CONTROLS?
Remember that NECC is still committed to supplying you with the largest pneumatic inventory in the USA. We also have the stuff that goes with it:
1. Compressed air supplies: Compressors, air dryers, fittings, tubing, regulators and more.
2. Cross-reference advice: Brand substitutes, accessories, obsolete replacements.
3. Pneumatic supplies: Stats, valves, actuators, relays, etc.
Honeywell Compact Zone Valve Actuators For Pneumatic Systems
One valve style–three separate operators.
Honeywell now offers a compact line of 1/2'' and 3/4'' zone valves. Ideally suited for today’s electronic control systems.
- Actuator mounts by hand
- Low space requirements
- Microprocessor-based positioner
- Plenum rated
Honeywell Pneumatic Valve Repair Kits
These replacement kits contain a completely assembled top and stem assembly, valve seat and all fittings necessary to connect either copper or plastic tubing. Only the existing valve body must be reused. Rebuilding can be done without removing the valve body from the line. Replacement top assemblies contain the metal top, fitting and diaphragm.

Honeywell Pneumatic Valve Actuators
These pneumatic actuators operate V5011 and V5013 valve assemblies.
They provide proportional control of steam or hot and cold liquids in HVAC systems.
Honeywell MP953 Replacement Diaphragms
Old style 5" diaphragms have a flat edge around the circumference while new style diaphragms have a beaded roll edge. They are not interchangeable.
Silicone diaphragms are used in operators requiring higher temperature ratings. They are interchangeable with neoprene diaphragms of the same style and size.
