Emerson DeltaV|A26-00139|Five-Valve Manifold
EMERSON A26-00139 Five-Valve Manifold for Differential Pressure
Description
EMERSON A26-00139 is a five-valve manifold designed for direct mounting to differential pressure transmitters, enabling instrument isolation, calibration, venting, and system integrity in liquid or vapor service.
Features
Compact, lightweight design reduces installation space and leak points.
Direct flange mounting to transmitter with 2⅛” (54 mm) centers.
Free-swiveling ball-end stem ensures bubble-tight shutoff and long service life.
Back-seat stem prevents blowout during operation.
PTFE or graphite stem packing resists washout and corrosion.
¼” NPT vent ports (plugged standard) allow safe vent routing.
