Johnson Controls Pneumatic Valve Actuator Spring Return

The Johnson Controls MP8000 Series spring return pneumatic valve actuator positions hot water, chilled water and steam control valves. It responds to a pneumatic signal from a controller. It suits commercial and institutional HVAC control systems, and it can be used as a replacement valve actuator.

Key Features:

• Universal application design: works with hot water, chilled water and steam control valves.
• Field-reversible action: lets you select spring-return-up or spring-return-down action on normally open valves.
• Molded synthetic rubber diaphragm: gives a constant effective area through the whole actuator stroke.
• Corrosion-resistant housing: the sturdy housing protects the internals from dirt and damage and helps ensure long service life.
• Position indicator: included with every actuator, it shows the valve stem position at a glance.
• Spring return operation: the spring drives the valve to a known position when air pressure is removed.

You can order a pneumatic or electric valve positioner separately. This is useful where sequential operation is wanted or extra positioning power is needed. Johnson Controls is a well-known name in building automation and HVAC controls. This product line gives dependable pneumatic control for existing building systems.
