What is a Manifold for
Instrumentation

An instrument manifold is a mechanism that unifies in a single element installation lines used for the protection, isolation, maintenance, venting / purging and calibration of industrial measuring instruments, mainly for pressure.

By unifying 2, 3 or 5 valves in a single element, we avoid leaking joints and achieve the described applications in a very small and reliable space.

What is a Instrumentation Manifold?

Nowadays an instrument manifold is a standard element or accessory in installations with differential pressure transmitters or instruments to control the fluids that affect this measuring device.

Using an instrumentation manifold we can:

Maintain fluid flow to the instrument.
Alerting of pressure changes required by the installation
Alerting of low flow levels required by the installation

What types of Manifolds for
Instrumentation exist

2-valve manifolds

For standard pressure switches, a 2-way manifold is usually used in the pipe line.
The standard 2-way manifold consists of a valve assembly and a drain with the following functions:
-Pressure switch calibration

5-valve manifolds

The normal use of a 5-valve instrumentation manifold is also for differential pressure switches Depending on the model and design of the 5-valve manifold you will find the usual use of 2 shut-off valves, 1 balancing valve and 2 bleed or test valves or other configurations.

3-valve manifolds

A 3-valve instrumentation manifold is used for differential pressure switches.

The usual configuration for a 3-way manifold is 2 shut-off valves and a balancing valve.

As a manufacturer of manifolds for instrumentation for more than 60 years, Zaes guarantees a quality product for your installations.

Do we need a Manifold at our premises with Measuring instrumentation?

Manifolds for instrumentation are very useful for different applications. From industrial machines to large industrial plants. By unifying different fluid lines in a system, instrumentation manifolds achieve more efficient results in terms of cost and energy expenditure.

These benefits include, for example, the following:

Lower installation costs by using a compact element that performs several functions and makes operation easier.
We avoid fluid leakage by using a compact block that reduces connections and installation lines to perform the functions required by our measuring instrument).
We improve the energy efficiency of our installations by requiring fewer fluid lines and therefore reducing the pressure drop and temperature loss in the installation, with lines without manifolds for instrumentation.
