Safety valves

At Alflow you will find a wide selection of safety valves - overtryksventiler and pressure/vacuum valves - in robust, reliable and durable designs. Our safety valves are designed to protect production lines and tanks containing gas or liquids from damage caused by overpressure or vacuum. The valves automatically release pressure from your tanks and production lines that contain gas/liquids, so you avoid damage to the system.

Protect your system with a safety valve

At Alflow, we know the importance of investing in a long-lasting product with high reliability. We therefore deliver durable solutions that are designed to ensure maintenance and efficient operation for a long time. And here a safety valve is particularly relevant.

With a safety valve from our range, you can protect production lines and tanks against damage that can be caused by overpressure or vacuum. This excess pressure or vacuum can, for example, be caused by temperature changes, filling of the system or a fire in the system. Here, the valve helps you relieve the system of excess pressure or vacuum in a safe and stable way.

If you therefore work within the pharmaceutical, process/chemical or food industry, and you need to be able to protect your tanks and your process equipment against overpressure or vacuum, then our safety valves will most likely be relevant to you. See all our good valves here.

In the range of safety valves, we have both industrial and sanitary pressure-relief valves. The industrial pressure-relief valves are calculated according to tank size and mode of operation and protect the tank against damage caused by overpressure by venting to the open air. This results in less evaporation due to the fact that normal "breathing" in the tank is reduced. The industrial pressure-relief valves are suitable for emergency relief on smaller tanks.

We also have a wide selection of industrial and sanitary pressure/vacuum valves for many applications to protect the tank from damage that can be caused by overpressure or vacuum. They are available, among other things, as pilot-controlled relief valves, modular vacuum valves and pressure/vacuum valves with built-in flame trap.

Our sanitary pressure/vacuum valves are sanitary equipment designed to protect tanks from pressure fluctuations and overpressure or to protect low pressure tanks not subject to DESP from pitting and/or overpressure.
Buy stainless-steel safety valves

At Alflow you can choose from different types of safety valves with useful properties, which are made of strong materials. In our range, for example, you can find both single and double relief valves that can handle a working pressure of between 0.5 bar and 10 bar. In addition, we only use carefully selected materials such as stainless steel and aluminium, which are of course also type-approved.

For you, this means a safety valve that meets the requirements that apply in relation to use, hygiene, the environment and serviceability. When you order valves from us, you can therefore better manage the pressure drop and flow without fear of poor quality. And of course you can also have full documentation delivered, such as ATEX, FDA and USP Class VI.

Our sanitary safety valves are also DESP-certified safety equipment designed to protect production lines and tanks containing gas, steam or Group 2 liquids against overpressure. They are manufactured in a hygienic design and are fully automatic, so they do not require any manpower to operate them.

In addition to safety valves, we sell a wide selection of products for flow and process systems, such as durable pumps, valves, hoses, fittings, tank equipment and the like. In addition, we offer service on flow products, whether onsite or offsite. At Alflow you will therefore find a one-stop shop with recognized brands.
