Description
Honeywell MP953C1075 – 8" Pneumatic Valve Actuator (8–12 psi Spring Range)
The MP953C1075 is a medium-force, 8" pneumatic actuator designed for precise modulating control of high-pressure steam, liquids, air, or noncombustible gases in HVAC and process systems. This actuator is ideal for applications where tight shutoff is not required, offering reliability and ease of installation.
Key Features
-
Rolling Diaphragm: Provides long service life and minimal hysteresis for accurate control.
-
Flexible Mounting: Can be installed after piping; slide-lock feature allows for quick valve stem engagement.
-
Direct Acting Operation: Expands on rising control signal.
-
Spring Return Design: Ensures fail-safe positioning in the event of air pressure loss.
-
Universal Compatibility: Interfaces easily with Honeywell’s globe valve lines (V5011, V5013, VGF).
