There are quite a few different types of connections used to install valves and other process components in the piping of process systems. While they all perform the same function of connecting the valve into the piping system and allowing it to perform its function, each connection type has its own pros and cons. The selection of the best valve connection type for your application is based on many factors:
Adding a manifold simplifies mounting and maintenance when using differential pressure for flow or level, or when measuring pressure directly. Manifolds can solve many application challenges while addressing the basic needs of mounting security and plumbing simplification.
Modern transmitter/manifold combinations are designed for versatility and user convenience. Many configurations with threaded or flange-faced inlets are available to accept piping from any direction
Current manifold designs can be as simple or complex as the application requires. Three basic configurations are used:
- A basic gauge or absolute-pressure transmitter.
- A conventional differential-pressure transmitter manifold.
- An integral manifold.
The basic gauge or absolute-pressure transmitter typically uses a manifold with a single-threaded inlet on the bottom. This provides isolation from the process fluid.
