Parker MPS856 Manual 3-way Slide Valve 15.7 Cv Npt

Product Description

The PARKER MPS856 is a manually operated 3-way slide valve with a 15.7 Cv flow rating, designed for industrial fluid or pneumatic control applications. The slide valve design provides positive shutoff and directional flow control through a manual slide actuator. With three positions and NPT threading, it integrates into standard piping systems without adapters. The MPS856 also functions as a safety lockout valve, making it suitable for lockout/tagout (LOTO) procedures during equipment maintenance and service. Licensed maintenance technicians and industrial pipefitters are the primary installers of this valve type.

The PARKER MPS856 is used in pneumatic and fluid control systems where manual flow direction and safety lockout capability are required. Its 3-way configuration allows it to route flow between ports or block flow entirely depending on actuator position. Typical applications include industrial process lines, machinery service isolation, and maintenance shutoff points where LOTO compliance is required. The manual slide actuator does not require an external power source, making it suitable for locations where electrical or pneumatic actuation is not available.

Installation Notes

Installation should be performed by a qualified pipefitter or maintenance technician. Depressurize and isolate the system fully before removing or installing this valve. Apply appropriate thread sealant to NPT connections per system requirements and applicable codes. Verify the valve is in the correct position before returning the system to service.
