How to choose the right valve assembly for your application

Many people know they need a valve assembly but are unsure which solution is right for their system. That is perfectly reasonable. Valve assemblies are used in everything from simple water installations to more advanced processes with high pressures and varying temperatures. The choice affects both function and longevity, so it's worth going through a few things before making a decision.

Difference Between ANSI and DIN Flanges

The difference between ANSI and DIN is simple. ANSI is an American standard that is based on British units of measurement, also called the imperial system, while DIN is a European standard that is based on the metric system. It is therefore important to know whether you need an ANSI or DIN standard to ensure that you get the right products.

Valves compliant with ANSI standards

At Axel Larsson, we are well known for our strong offering in valves with DIN flanged connections. At the same time, we want to make it clear that we also offer valves according to ANSI standards, for example with good availability on Peko's ball valves, which are manufactured in Spain.

How an automated valve assembly works

A valve assembly is a finished unit in which the valve and actuator are assembled. When the control is done automatically via electricity or compressed air, it is instead called an automated valve assembly. This means that flows can be regulated without manual handling, which streamlines processes and increases control in the plant.

Compensators - Product overview, function and use

Compensators are flexible components that are installed in piping systems to absorb movement, dampen vibration, and protect equipment from mechanical stress. By compensating for thermal expansion, pressure fluctuations and mechanical movements, they contribute to the stable, safe and long-term operation of industrial plants.

Rubber Compensator with SAE Flanges for Hydraulics

Rubber compensators, made of elastic rubber, absorb movement and vibration, protect pipes and valves from damage, and dampen sound and reduce the risk of leakage. In addition to compensators with European standard flanges, we can also offer versions with SAE flanges.

Valve packages and valves with actuators – advantages over manual valves

In many industrial processes, valves are a central component for controlling the flow of process media such as water, air, gas. Traditionally, many facilities have used manual valves that open and close by hand. Valves with actuators, on the other hand, offer several clear advantages that make them a more efficient and safe choice in today's industry.

How often should valve assemblies be maintained?

When valves and actuators are part of a process plant, they are often such a natural part of the operation that they are easily forgotten – until something suddenly starts to run sluggishly, leaks or stops working. Regular maintenance is therefore one of the most important measures to avoid downtime and extend the life of both valves and actuators.

What is a valve assembly? – A Complete Guide for Beginners

If you work in industrial processes or flow control, you may have heard of valve assemblies or valve packages but wondered what they actually are. Basically, it is a ready-made device that combines valves and actuators with accessories, tested and ready for operation. This allows you to control flows such as water, air, gas or process media safely and efficiently without having to select and assemble each component separately.

Double-Eccentric Butterfly Valves

Double-eccentric butterfly valves are designed for applications where sealing, service life, and operational reliability are of particular importance. With the double-eccentric design, friction during opening and closing is reduced. These valves can also handle higher pressures and temperatures compared to a single-eccentric butterfly valve.
