Control valves
With Alflow control valves, your ventilation, heating and cooling systems are guaranteed fast regulation and precise flow. At the same time, we make sure that our control valves protect your pipes and equipment from high pressures as they are made of the most suitable material - ideal for regulating a variety of liquids, gases and gases.
Our control valves are available in stainless steel, carbon steel and bronze, among others.
In addition, our control valves from Steriflow are equipped as standard with the patented JORLON diaphragm, which is a reinforced modified PTFE with FDA and USP Class VI approval. The JORLON diaphragm comes with a LIFETIME WARRANTY, which means that you can return the valve at any time in the unlikely event of a diaphragm failure.
The extra-wide JORLON diaphragm, which ensures fast and precise regulation, contributes to reduced costs and less time spent on maintenance and service.
Find the best quality control and pressure reducing valve
At Alflow, we value customer satisfaction and good quality. That's why we strive to deliver the best pressure reducing valves and pressure control valves on the market for your business. This also means that we offer a wide range of different control valves. Among other things, you can find:
- Pressure holding valves
- Pressure reducing valves
- Flow control valves
- Temperature control valves
- Modulating control valves
- Sanitary gas back pressure regulators
- Hand control valves
The control valve can be an integrated unit with an output pressure setting, a limiter and sensors throughout the valve body, or the valve can consist of a separate pressure sensor, regulator and flow valve.
We have a wide range of control valves for your process. For example, the MK80 control valve with sliding-gate trim for fast and precise flow shut-off is ideal for temperature control in industrial applications, while the Mark978 Inline is designed to meet the stringent specifications of sterile processes and is great for controlling clean air or gas.
The Mark978 Inline valve is also drainable in all positions, ensuring that there is no build-up of excess media in the valve. The unique shutter design ensures a long service life and low maintenance costs as the travel from open to closed position is significantly shorter than similar control valves.
In addition to regulators, you can also order a number of other types of valves from us - such as solid globe valves, butterfly valves, safety valves, ball valves and more.

A durable solution for your installations
All our control valves are of course of high quality, so you can be completely confident in using our products for your processes. Among other things, our control valves are type-approved and fulfil all industrial requirements in terms of application, hygiene, environment and user-friendliness.
In addition, all our control valves are tested before use to ensure they meet quality and safety requirements. The high standards are also reflected in our suppliers, who fulfil all requirements from directives and standards within the food industry as well as the chemical and pharmaceutical industry.
When you buy control valves from Alflow, you get a long-lasting solution. All this hard work is important because we know that good valves are crucial in applications where you need to control and regulate flow. That way, pipes and equipment are protected against high pressures and pressure surges.
How a control valve works
Do you have a heating, cooling, ventilation or other system that uses either gas or liquid to operate? In most cases, it is very important to be able to control and regulate the amount of liquid flowing through the pipes and into the appliance.
And you can do that with a control valve. Generally speaking, you can divide control valves into the categories of volume control valves, pressure control valves and temperature control valves. The purpose is to reduce the pressure of a fluid to a certain value when it comes out of the control valve.
For example, a pressure reducing valve for private homes helps protect water installations from excessive pressure from the supply. Otherwise, your house would get very hot if you couldn't regulate the amount of water going into your radiators. For this reason, it's important that you can control how much liquid or gas is passed through the valve, whether in your home or in your process.
So the control valve helps maintain a constant output pressure and you can usually set the valve to a certain pressure within its limits. When the control valve is set, the reduced pressure will be constant. In addition, a lower outlet pressure will also create lower water consumption. A constant level in the operating flow reduces noise in the installation.
Get expert advice, sparring and service
With a pressure reducing valve, you can keep the set pressure at a constant level - even if there are fluctuations in the inlet pressure. Finding the right control valve is essential to protect your devices and ensure stability at low flow.
That's why we are happy to advise you on finding the best solution for your business. Among other things, we help you select the valve from a valve curve based on fluid data, capacity and pressure drop. Fluid data can be, for example, type, temperature, viscosity, abrasives or solids.
These factors influence the choice and size of the valve, as well as the choice of elastomers and surface finishes. You are therefore more than welcome to Ask us for advice. If you need more information about a specific pressure reducing valve in our selection, we will of course be happy to tell you more about that too. So if you are looking for control valves for installation in your process plant, you have come to the right place.
Of course, we also have many other flow products besides valves in our range. We have a wide range of pumps - for example centrifugal pumps, dosing pumps and screw pumps - hoses, pipes & fittings, gaskets, sight glasses, mixers, heat exchangers and much more, so you can always get a complete solution for your installation.

What is a control valve?
A control valve has many benefits. The valve is used for flow control in process systems, including manual or automatic control (actuator) of flow, pressure, temperature, concentration, liquid level in tanks, etc. A control valve typically has a plug/seat design where the plug continuously moves up and down to adjust the process condition. With a control valve, you can achieve very precise regulation even at low flow.
What types of control valves are there?
There are a number of different types of control valves available for different types of applications - including manual valves with handles for simple process control, automatic valves for air/electrical control, automatic diaphragm valves for automatic process control with a spring/diaphragm loaded actuator and aseptic valves.
How to find the right control valve?
A control valve is typically selected from a valve curve based on fluid data, capacity and pressure drop across the valve. Here, it is especially important that the size of the valve fits the total pressure drop. To ensure correct valve selection for precise regulation and control of flow, it's important to consider all necessary process and site data as well as customer preferences.
