Control valves

Control valves are essential components in many industries. They help regulate flow, pressure levels, and temperature across various applications. We offer a wide range of control valves designed to meet different requirements and challenges, including pressure-reducing, pressure-relief, and temperature-regulating valves.

14RESULTATER NULSTIL

The M51 series is mechanically directly controlled pressure relief / pressure reduction valve. Single or double seat.

The MM series is spring-loaded, self-activated, directly controlled valve, and is available as well as pressure-reducing and pressure-relieving / counter-pressure regulating valves. The main function of the pressure reduction valve is to adjust the flow of the medium (gas, steam or liquid) through the regulator to the demand for the medium in the system.

The BPM series is spring-loaded, self-activated, directly controlled valve, and is available as well as pressure-reducing and pressure-relieving / counter-pressure regulating valves. The main function of the pressure reduction valve is to adjust the flow of the medium (gas, steam or liquid) through the regulator to the demand for the medium in the system.

This valve type MAXOMATIC is characterized by the fact that there are no mechanical moving parts or sliding guides, thereby ensuring an extended service life and a unique reliability.

AT series even modulating temperature regulator, which utilizes steam pressure as the activating force. The reason for the rapid reaction is due to bellows seal, calibrated spring and the low thermal inertia. All of this makes the regulator respond quickly to very small deviations at the controlled temperature.

What Are Control Valves?

Control valves are critical for regulating the flow of liquids or gases in a pipeline system. Whether you're managing pressure, flow rate, or temperature, control valves help maintain optimal performance and safety. Depending on the setup, they can be configured for manual, self-acting, or automatic operation.

At Insatech, we offer a broad selection of control valves - with a special focus on Carraro valves, known for their durability, precision, and efficiency in demanding industrial and marine applications.

Applications of Control Valves

Control valves are widely used in oil & gas, chemical processing, power plants, and water treatment systems. They regulate key process variables and ensure stable, efficient operation.

Our range of Carraro control valves is suitable for both standard installations and complex systems requiring tight control and reliable long-term performance.

Functional Types We Offer

We supply Carraro valves with a wide range of functions, including:

Pressure relief valves – to protect systems from overpressure
Back pressure valves – to stabilize upstream pressure
Pressure-reducing valves – to ensure consistent downstream operation
Flow regulators – to manage precise throughput
Microflow control valves – for ultra-low flow applications in laboratories or precision processes
Level control valves – to maintain tank or reservoir levels
Temperature control valves – to manage steam or thermal transfer fluids

All Carraro valve types are engineered for high reliability and minimal maintenance.

Selecting the Right Control Valve

Choosing the correct control valve depends on several factors: pressure range, media type, system configuration, and environmental conditions. Carraro valves are manufactured in various materials and trims to match these diverse requirements - whether for aggressive fluids, steam, or precise modulation tasks.

With proper segmentation by application, we can offer Carraro control valves tailored to each industry’s operational needs.

Our Control Valve Portfolio

We carry a wide range of Carraro valves and complement them with Masoneilan models from Baker Hughes for advanced automation or specialty demands.

Carraro UBAN – Self-Acting Pressure Regulators

The Carraro UBAN series is a line of direct-acting, spring-loaded pressure-reducing valves. These Carraro regulators are built for steam, gas, and liquid service, and excel in maintaining system stability with minimal operator intervention.

Carraro Flow and Pressure Control Solutions

In addition to UBAN, we supply other Carraro valve models for pressure control, back pressure regulation, and flow limitation. Their robust construction and consistent performance make them ideal for marine, chemical, and energy sector applications.
