The 2-Valve Instrument Manifold – Direct Mount (Non-Flanged Transmitter) is a block-type manifold designed for direct installation on differential pressure transmitters without flange connection.
It integrates two isolation valves within a compact body to control the high-pressure and low-pressure impulse lines of the transmitter.
The manifold connects to the process through 1/2 NPT threaded ports and mounts directly to the transmitter interface, forming a compact impulse line assembly without additional tubing adapters.
A 1/4 NPT vent/test port is provided for pressure release, calibration, or test connection.
The structure is specifically designed for coplanar or similar non-flanged pressure transmitters, enabling stable mechanical installation and reliable pressure sealing between the process line and the instrument.
The integrated block design reduces connection points and improves installation integrity in pressure measurement systems.

Keunggulan Produk
Improved sealing safety
Back-seat structure protects packing and prevents leakage during full opening.
Reduced stem wear
Non-rotating lower stem minimizes friction and extends service life.
Stable operation
Screw-locked handle prevents loosening under vibration or pulsation conditions.
Contamination-free sealing
Stem thread lubrication isolated from process medium ensures clean pressure transmission.
Compact installation
Direct mount structure reduces tubing connections and leak points.
This type of valve manifold is specially designed for Rosemount “coplanar” pressure transmitters (including models 3051C, 3051S, 2024 and 3095).
The standard configuration of each valve manifold of this model includes four 7/16″ UNF × 2.08″ high-strength bolts. It can be directly mounted to the transmitter.
