Manometric cocks and tubes

Manometric taps and tubes - essential elements of measuring systems

In the world of hydraulics and pneumatics, pressure taps and tubes play a key role.   They provide precise pressure measurements in installations. Their selection is of great importance for the safety and efficiency of the systems. At Onninen we offer a wide selection of these components from renowned manufacturers.

Manometer cocks are important accessories for manometers. They enable controlled connection of the measuring device to the installation. They allow you to safely isolate the manometer from the system. This is useful during maintenance or replacement of the device.   Our offer includes manometric cocks of various diameters and materials.   Brass, stainless steel and plastic models are available.

Manometer tubes are a supplement to cocks. Their task is to protect the manometer from direct contact with the medium. They reduce pressure and temperature fluctuations of the working medium. In this way, they extend the life of the measuring device. We offer U-shaped, spiral and loop siphon tubes. Their selection depends on the specifics of the given installation.

Manometric taps and tubes - how to choose the right ones?

Selecting the right valves and manometer tubes requires professional knowledge.   Installation parameters such as pressure, temperature and type of medium are of key importance.   In the case of high temperatures, we recommend using siphon tubes. They effectively reduce the temperature of the medium reaching the manometer. For installations exposed to strong vibrations, we recommend loop tubes. They dampen vibrations and protect the delicate mechanism of the device.

When selecting a manometric valve, pay attention to its diameter. It should be adapted to the connecting threads of the manometer and the installation. The material of the valve is also important. For aggressive media, we recommend using stainless steel or plastics. For standard installations, brass valves will work well.

• For high temperatures - siphon tubes
• For strong vibrations - loop tubes
• For aggressive media - stainless steel or plastic taps
• For standard applications - brass taps

In our daily practice we often encounter questions about the selection of manometric taps and tubes.   Recently, we advised on the protection of pressure gauges in a project for a large industrial plant. The installation was characterized by high temperatures and pressures. We proposed a combination of stainless steel taps with siphon tubes. This solution ensured safe and long-term operation of the measuring system.

The best brands of manometer taps and tubes in the Onninen offer

At Onninen we rely on proven solutions from renowned manufacturers.   Our offer includes manometer valves and tubes of such brands as Afriso, Wika, Danfoss, Huber and Watts.   Each of them specializes in specific solutions. Afriso is known for its reliable brass cocks for standard applications. Wika offers a wide range of stainless steel siphon and loop pipes. Danfoss products are suitable for refrigeration and air conditioning installations.

In addition to the renowned brands, our range also includes our own brand products. These include Onnline and FXA manometric accessories. They offer a good price-quality ratio. They are suitable for less demanding applications.   Our experience shows that private label products are very popular among installers.   They appreciate their affordable price while maintaining adequate quality.

Many customers ask us about immersion sleeves and temperature sensor pockets. These are elements that complement measurement systems. Immersion sleeves protect temperature sensors from direct contact with the medium. Pockets, on the other hand, allow sensors to be mounted in hard-to-reach places. Our offer includes a wide selection of these accessories.

• Immersion sleeves - protection of temperature sensors
• Sensor pockets - installation in hard-to-reach places
• Gauge cocks - safe shut-off of gauges
• Siphon tubes - lowering the temperature of the medium
• Loop tubes - vibration damping

In the case of reorganization of industrial installations, we most often recommend a comprehensive replacement of measuring equipment. This includes not only the instruments themselves, but also taps, pipes and mounting accessories.   This approach ensures system consistency and minimizes the risk of failure.   We recently completed a project to modernize an industrial boiler room. We replaced all the pressure gauges and accessories with new ones. We used Afriso pressure taps and Wika siphon tubes. The client appreciated the comprehensive approach and professional advice.

Manometric taps and tubes - practical applications

Manometric taps and tubes are used in many branches of industry and infrastructure.   In heating systems, they are used to monitor water pressure in circuits. In gas installations, they provide safe measurement of fuel pressure. The chemical industry uses them to control technological processes. In refrigeration and air conditioning systems, they monitor the operation of compressors and heat exchangers.

An interesting example of application is the food industry. Here, hygiene and the possibility of cleaning the installation play a key role. For such applications, we recommend taps and pipes made of acid-resistant steel. They are resistant to aggressive cleaning agents. In breweries, for example, they are used to monitor pressure in fermentation tanks. In dairies, they control the operation of pasteurizers and homogenizers.

Our experience shows that the proper selection of valves and manometer tubes translates into long-term and failure-free operation of the installation.   We recently advised on the modernization of a water treatment plant. We used manometric cocks with the option of venting. This solved the problem of air bubbles accumulating in the connecting pipes. Thanks to this, stable and reliable pressure readings were obtained throughout the system.

In the petrochemical industry, manometer valves and tubes must meet strict safety standards. For such applications, we recommend products with ATEX certificates. They are designed for use in explosion-hazardous areas. Our offer includes Wika manometer valves with appropriate certificates. They are suitable for use in refineries and oil processing plants.

Onninen, as an expert in the field of manometer valves and tubes, provides professional advice. Our specialists will help you choose the optimal solutions for specific applications. We also offer technical support during the assembly and start-up phase.   We invite you to contact our branches throughout Poland.   Together we will find the best solutions for your measurement installations.
