Relief-relief valves

Pressure relief valves - a key element of hydraulic installations

Pressure relief valves are essential components in many hydraulic systems.   Their main task is to control the pressure in the installation. They prevent excessive pressure increase. In this way, they protect the entire system from damage. At Onninen, we offer a wide selection of these devices. Our products meet the highest quality and safety standards.

We often come across questions about selecting the right valve. Understanding the specifics of a given installation is key. Important parameters include maximum operating pressure and flow. The temperature of the medium is also important. Our offer includes valves for various applications. We have models for water, oil, air and other media.

Types of pressure relief valves available at Onninen

Our assortment includes several main types of valves:

• Relief valves - protect against sudden pressure increases
• Relief valves - regulate the pressure continuously
• Combination valves - combine relief and relief functions
• Proportional valves - provide precise pressure control

Our company provides products from renowned brands and our own solutions.   Among the available manufacturers are Onnline and FXA. These are our own brands, guaranteeing an excellent price-quality ratio. We also offer recognized brands such as Opal or Prof. Every customer will find the right solution with us.

Criteria for selecting pressure relief valves

Choosing the right valve is a key issue for the safety of the installation. In our daily practice, we see how important an individual approach is. Each system has its own unique requirements. The main selection criteria are:

• Maximum operating pressure of the installation
• Required flow
• Type of medium (water, oil, air, etc.)
• Operating temperature
• Material of construction (brass, stainless steel, etc.)
• Connection type (threaded, flanged)

Our experience shows that it is worth consulting an expert when selecting a valve.   At Onninen we offer professional technical advice. Our specialists will help you choose the optimal solution. We will take into account the specifics of the installation and the client's budget.

Recently, we were selecting valves for a large industrial plant project. The client needed devices to work with an aggressive medium. We suggested valves made of acid-resistant steel. They met all the requirements and proved themselves in difficult conditions.

Practical applications of pressure relief valves

Pressure relief valves are used in many industries. They are often used in industry, energy and construction. Here are some examples:

In heating systems, valves protect boilers from excessive pressure. In water supply systems, they regulate the pressure in the network. In power hydraulics, they protect pumps and actuators. In the food industry, they guarantee the safety of production processes.

Many customers ask us about solutions for modernizing older installations.   In such cases, we often recommend combination valves. They combine relief and relief functions. This allows for system optimization with minimal intervention.

Onninen recommends using high-quality valves. They provide long-term and failure-free operation. This translates into lower operating costs and greater safety. It is worth investing in proven solutions from renowned manufacturers.

In the case of reorganization of production lines, a comprehensive analysis is most often needed. Our engineers help in selecting the right valves. We take into account changes in flows and pressures. Thanks to this, the system works optimally in the new conditions.

Onninen offers a full range of services related to pressure relief valves.   We provide technical advice, equipment selection and after-sales support. Our team is available to help at every stage of project implementation. We encourage you to contact our specialists. We will help you choose the optimal solutions for your installation.
