Selection criteria for EA class anti-pollution valves

Selecting the right EA class anti-pollution valve requires taking into account many factors. The installation parameters and the specifics of the facility are of key importance. Legal requirements and industry standards are also important.

When selecting a valve, consider the following:

  • Connection diameter
  • Operating pressure in the installation
  • Working temperature
  • Type of medium
  • Maintenance and service requirements

At Onninen we offer professional advice on valve selection.   Our specialists will help you choose the optimal solution. We will take into account the specifics of the given installation and the customer's needs.

Practical applications of EA class anti-pollution valves

EA class anti-pollution valves are widely used in various industries. They are necessary wherever there is a risk of contamination of drinking water. We often come across questions about specific examples of their use.

In the food industry, these valves protect production lines. They prevent chemicals from entering the water supply network. In hospitals, they protect installations from biological contamination. In industrial plants, they protect against the reverse flow of contaminants.

We recently completed a project for a large shopping center.   We used EA class anti-contamination valves in the fire protection system. They protected the water supply network from potential chemical contamination.

When modernizing older buildings, we often recommend installing modern valves. They increase safety and compliance with current standards. Many customers ask us about the possibilities of modernizing existing installations.

Our experience shows that investing in high-quality valves pays off. They provide long-term protection and minimize the risk of failure. In everyday practice, we see how important this is to our customers.

Onninen recommends the use of class EA anti-pollution valves at all critical points in the installation.   They are particularly important at the connection points of different water systems. They guarantee safety and compliance with applicable regulations.

It is worth remembering that EA class anti-pollution valves require regular inspections. They ensure proper operation and long service life of the devices. At Onninen we offer comprehensive support in this area.

For many of our customers, ease of installation and service of valves is key. That is why our offer includes installer-friendly products. Valves with monitoring capabilities facilitate regular inspections and maintenance.

In case of office reorganization we most often recommend the installation of 1/2-2 inch valves.   They are ideal for securing installations in social rooms and bathrooms. They provide protection against backflow from sanitary facilities.

For industrial facilities, we often recommend DN 50-150 flanged valves. They are suitable for installations with large flows. They guarantee effective protection even in the most demanding conditions.

At Onninen, we focus on comprehensive solutions. In addition to the valves themselves, we offer mounting accessories and tools. This makes it easier for our customers to complete projects from A to Z.

EA class anti-pollution valves are not only a legal requirement, but above all a guarantee of safety.   They protect the health of users and prevent costly failures. Investing in high-quality valves is an investment in peace and safety.

We invite you to contact our advisors. They will help you choose the optimal solutions in the field of EA class anti-pollution valves. Together we will take care of the safety and efficiency of your water installations.
