Introducing our industrial instrumentation assemblies that integrate siphons, dampers and gauge valves into a single modular solution.

In modern industry, accurate and reliable pressure measurement is essential to ensure operational safety. However, the installation of a pressure gauge alone is not sufficient to ensure stable measurement, especially in systems where pulsations, high temperatures, vibrations or the risk of water hammer are present. Aware of this need, ZAES presents its industrial instrumentation sets, which comprise siphon tubes, pressure dampers and pressure gauge valves in a single compact, safe and ready-to-install system.

This assembly, developed according to the recommendations of international instrumentation manufacturers, creates a much more reliable measuring line, reducing breakdowns and extending the life of the gauge by up to six times.

Why industry needs pre-configured instrumentation sets

A common mistake in installations is to mount pressure gauge accessories without considering their synergy with each other.
In a typical line, we can find:

• keystrokes (generated by pumps, compressors, hydraulic presses),
• high temperatures (steam, thermal oils),
• constant vibrations,
• corrosion,
• risk of water hammer,
• need for regular maintenance.

The result:
Unstable readings, instrument breakage, fluid leakage, mechanical fatigue and operational risk.

Therefore, the ideal set should include three essential elements:

1. Siphon (thermal protection)
2. Shock absorber (protection against impact and shock)
3. Pressure gauge valve (safety and maintenance)

ZAES is aware of this reality and has designed a system that integrates these three elements in a natural way, ensuring full compatibility, correct operation and quick assembly.

The ZAES instrumentation package: three components, one system

The sets ZAES are designed for applications where it is necessary to ensure stable, safe and durable measurements. Each component fulfils a specific and essential function:

1. ZAES siphon tube - Essential thermal protection

A siphon is mandatory in any installation where the fluid reaches high temperatures, especially steam. Its function is to create a condensate chamber which reduces the temperature of the fluid before it reaches the pressure gauge.

Technical benefits of the siphon:

• Thermally insulate the pressure gauge.
• Avoids deformation of the Bourdon tube.
• Reduces thermal shocks.
• Prolongs the life of the instrument.
• Maintains calibration for a longer period of time.

ZAES siphons are available in different versions:

• U-type,
• pigtail type (Straight)

and made of carbon steel or stainless steel AISI 316.

2. ZAES shock absorber - Pulsation and water hammer protection

The shock absorber regulates the pressure transmission to the instrument. Its purpose is to smoothing the pulsating wave of the fluid so that the pressure gauge needle remains stable.

Advantages of the ZAES shock absorber:

• Progressive pulse filtering.
• Reduction of water hammer.
• Prevention of mechanical damage to the pressure gauge.
• Greater reading stability.
• Ideal for reciprocating pumps, compressors and hydraulic systems.

It is available in both carbon and stainless steel, and with options for clean, viscous or particulate fluids.

3. Pressure gauge valve ZAES - Safe isolation and maintenance without downtime

The valve allows the instrument to be isolated without stopping the operation, which is crucial in continuous process installations.

Key functions:

• Safely remove, bleed or replace the pressure gauge.
• Perform calibrations without interrupting the process.
• Avoid leaks during maintenance.
• Work with progressive closure to avoid damaging the instrument.

These valves are available in carbon steel or stainless steel, with BSP or NPT connection.

Advantages of using an instrumentation package instead of individual components

Installing loose fittings can generate:

• incompatibility of threads,
• alignment difficulties,
• installation errors,
• loss of watertightness,
• operational risks,
• unstable readings.

The sets ZAES eliminate these problems with turnkey solutions.

Clear advantages for the user:

    -    Guaranteed compatibility

All components are designed to fit together without the need for adapters.

• Faster installation

Fewer connection points mean less assembly time.

• Reduced risk of leakage

Being designed as an assembly, they minimise unnecessary joints.

• Increased operational security

The system complies with best instrumentation practices.

• Maintenance savings

A well-assembled system reduces interventions and avoids premature failures.

Sectors where ZAES arrays are particularly useful

ZAES instrumentation sets are recommended for:

• Steam and thermal generation plants

Protection against heat and pulsation is mandatory.

• Chemical and petrochemical industry

Aggressive processes requiring maximum reliability.

• Industrial hydraulics

Piston pumps and presses that generate intense pulses.

• Food and pharmaceuticals

CIP/SIP lines and thermal intensive processes.

• Industrial gas and pneumatic networks

Need for stability and operational security.

• Paper, textile and metal industries

Steam processes and frequent thermal fluids.

Comparison: ZAES instrumentation assembly vs. traditional assembly

ZAES versus international competitors

Like WIKA, Ashcroft or Badotherm, ZAES offers complete instrumentation solutions.
The difference is that ZAES combines:

• European quality,
• rapid availability,
• competitive prices,
• specialised technical support,
• global BSP/NPT compatibility,
• and ready-to-install modular solutions.

This makes ZAES a particularly attractive option for integrators, engineering companies and industrial plants looking for uncomplicated reliability.

In short: ZAES instrumentation sets enhance the protection and reliability of any pressure system.

The new ZAES instrumentation sets The integrated siphons, dampers and gauge valves represent a robust, efficient and safe solution for any industrial environment.
They reduce risks, extend instrument life and offer a higher standard of quality and safety.

They are the ideal choice for those looking for a robust, durable and easy-to-install metering system.
