FANs 977, 1628.3Product BulletinMP8000Issue Date0301©2001 Johnson Controls, Inc.1Code No. LIT-977257www.johnsoncontrols.comMP8000 Series Pneumatic Valve Actuators aredesigned to accurately position chilled water,hot water, and steam control valves in response to apneumatic signal from a controller. A pneumatic orelectric valve positioner can be ordered separatelyfor use in applications where sequential operationis desired or additional positioning power is necessary.MP8000 Series actuators have a molded, syntheticrubber diaphragm contained in a sturdy,corrosion-resistant housing that protects against dirtand damage. This molded diaphragm provides aconstant effective area throughout the actuator stroke.Figure 1: MP8000 SeriesPneumatic Valve ActuatorsFeatures and BenefitsDesigned for Use inHot Water, Chilled Water,and Steam ApplicationsAllows for universal applicationField-Reversible ActionAllows for selectable spring-return-up orspring-return-down action on Normally Open(N.O.) valvesCorrosion-ResistantHousingEnsures long life by providing strength andcorrosion resistancePosition Indicator Includedwith Every ActuatorProvides visual indication of valve stempositionMP8000 SeriesPneumatic Valve Actuators2 MP8000 Series Pneumatic Valve Actuators Product BulletinTable 1: Ordering DataMP8Pneumatic123Valve Actuator2Size and2 = 25 sq in.

The pistonwill move the valve stem and plug until the diaphragmpressure balances the actuator return spring force andthe fluid forces. Reducing the air pressure permits thespring to return the valve plug to its normal position.With no control air pressure applied to the diaphragm,the valve is in the normal position.For applications requiring stable, accurate control andsequencing, a V-9502 Pneumatic Valve ActuatorPositioner or an EPP-1000 Electro-Pneumatic ActuatorPositioner is available for mounting in the field. Referto Table 3 for a list of positioners and positionermounting kits available.Both styles of positioners are factory calibrated tomatch the nominal spring range of the valve andactuator assembly. For more information regardingthese positioners, refer to the V-9502 Pneumatic ValveActuator Positioner Product Bulletin (LIT-977265) orthe EPP-1000 Series Electro-Pneumatic PositionersProduct Bulletin (LIT-2681270).AccessoriesTable 2: Mounting Kits (For Field Assembly)DescriptionCode NumberMounting Kit for MP82, MP83, MP84, or MP85 Series Actuators Mounted to 2-1/2, 3, or4 in.
