Description
Honeywell MP953D1172 – 7" Pneumatic Valve Actuator (3–7 psi Spring Range)
The MP953D1172 is a medium-force, spring-return pneumatic actuator engineered for precise, proportional control of steam, hot water, or chilled water valves in HVAC systems. Designed to operate V5011, V5013, and VGF valve assemblies, this actuator delivers reliable performance in both new installations and retrofit applications.
Key Features
-
Rolling Diaphragm Design: Ensures long actuator life and minimizes hysteresis for more accurate control.
-
Flexible Installation: Easily attaches to valves—even after piping—and requires no special tools.
-
Slide-Lock Mechanism: Simplifies engagement to the valve stem for quick setup and service.
-
Spring Return Fail-Safe: Ensures valve returns to a default position on loss of air pressure.
-
Direct or Reverse Acting: Configurable to meet specific system control requirements.
-
Compact, Durable Construction: Suitable for demanding commercial HVAC environments.
