2, 3 and 5 Valve Manifolds: The Accurate ZAES Solution for Industrial Pressure Control

In a highly competitive market such as the industrial valves and fluid control systems, having a reliable technology partner can make the difference between operational efficiency and the risk of unplanned downtime. At ZAES, we are positioned as a leader in high precision instrumentationoffering 2-, 3- and 5-valve manifolds designed to ensure safety, efficiency and operational continuity in critical industries such as the petrochemicals, energy, pharmaceuticals and water treatment.

What is an Instrumentation Manifold and why choose ZAES?

A instrumentation manifold is a set of valves to control, isolate, equalise and bleed off pressure in measuring equipment such as differential pressure transmitters y pressure gauges. At ZAES we design our manifolds with the highest standards of quality and precision, competing at the level of large international manufacturers such as Swagelok, Parker or Hy-Lok, but with the advantage of a close, personalised approach adapted to the specific needs of each customer.

ZAES Manifolds: Precision and Safety in Every Configuration

2-Valve Manifold: Efficient Simplicity

Composition:

• 1 blocking valve
• 1 bleed valve

Ideal for simple pressure measurement applications where differential calibration is not required. This type of manifold is commonly used in water treatment plants, industrial HVAC systems and environments with stable pressure conditions.

Key Benefits:
- Low cost
- Easy installation and operation
- Fast and safe insulation

3-Valve Manifold: Differential Pressure Accuracy

Composition:

• 2 blocking valves (high and low pressure)
• 1 equalisation valve

Designed for differential pressure transmittersThis manifold is the standard in refineries, chemical plants y power plants. Its ability to equalise pressures prior to calibration prevents equipment damage and ensures accurate readings.

Outstanding Benefits:
- Protection of critical instrumentation
- Facilitates calibration without disconnections
- Longer sensor lifetime

5-Valve Manifold: Maximum Control and Professional Maintenance

Composition:

• 2 blocking valves
• 1 equalisation valve
• 2 bleed valves

It is the most advanced and versatile option on the market. Ideal for sectors that require high precision, continuous maintenance and minimum disruptionas the pharmaceutical industry, offshore oil and gas platforms, y food processing.

Exclusive Features:
- Accurate calibration without stopping the process
- Safe purging of air and pollutants
- Full control of the measuring system
