Coplanar manifolds Coplanar manifold with a 3-valve assembly and direct process connectionĬoplanar manifolds have the process connection coming in from the bottom and don’t require a process flange. Female process connections are standard for these manifolds, but male process connections are also available.
These manifolds are only available as a 2-valve assembly with a ½” NPT process connection. This style manifold connects to transmitters using male National Pipe Thread (NPT). Direct connect/inline manifolds Direct connect manifold with 2-valve assembly and ½” process connectionĭirect connect manifolds, also called inline, or block and bleed manifolds, have either female or male process connections. There are four types of manifolds - direct connect, coplanar, traditional, and conventional. Now, let’s move on to different types of manifolds. Application: When you need to block, equalize, and vent two process connections.Application: When you need to block each process connection or equalize two sensor diaphragmsĥ-valve manifolds are used on differential pressure transmitters.Application: When you need to isolate the transmitter and vent the pressure offģ-valve manifolds are used on differential pressure transmitters.2-valve assemblyĢ-valve manifolds are used for gauge pressure transmitters. Manifolds are used to isolate process connection(s) using 2, 3, or 5 valves. Automation Service Manifold Assembly Types & Sizes To help you in the selection process, we put together this quick visual guide help to get you started.įirst, let’s break down manifold assembly types and their common applications. Whether you’re refining your process controls in an oil field, chemical manufacturing plant, pulp and paper shop, or an energy production facility, determining which manifold you need for your transmitters can be a little tricky.
