What an instrumentation
manifold is?

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

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

What an instrument manifold is used for?

Currently, an instrumentation manifold is a standard element or accessory in installations with transmitters or differential pressure instruments to control the fluids that affect this measurement device.

Using an instrumentation manifold we can:

Maintain the flow of fluid that reaches the instrument.
Warn of low flow levels required by the installation
Warn of pressure changes required by the installation

How many types of instrumentation
manifolds there are?

2 valves manifolds:

For standard pressure switches, the 2-way manifold is usually used in the pipeline. The standard 2-way manifold is made up of a set of valves and a drain with the following functions:

-Pressure switch calibration

5 valves 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, we will find the usual use of 2 cut-off valves, 1 for balancing and 2 for purging or testing or other configurations.

3 valves 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.

At Zaes, as a manufacturer of hose fittings and a manufacturer of valves for viscous liquids, we manufacture a quality product thanks to our experience of more than 60 years.

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

Instrumentation manifolds are very useful for different applications. From industrial machines to large industrial plants. By uniting different fluid lines in one system, instrumentation manifolds achieve more efficient results in terms of costs and energy consumption.

Benefits among which we can find, for example, the following:

Lower installation costs by using a compact element that performs various functions and makes operation easier.
We avoid fluid leaks 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 facilities by requiring fewer fluid lines and therefore reduce the pressure drop and temperature loss, in the installation, with lines without instrumentation manifolds.
