This remote-mount 3-valve manifold provides:
- Process isolation
- Pressure equalization
- Safe venting
for differential pressure transmitters and gauge installations.
The screw-locked handle ensures stability under vibration, and the stem lubrication is isolated from the process medium, preventing contamination and extending service life.
Designed for high-pressure industrial instrumentation systems, the manifold supports threaded process connections and multiple configuration options suitable for various installation layouts.
