Pressure gauge valve 910.11, stainless steel, M20 x 1.5 male thread, M20 x 1.5 mounting nut 9092358

DIN pressure gauge valve for isolation of measuring instruments

The model 910.11 DIN pressure gauge valve is a key component of measuring installations in hydraulic and pneumatic systems. The device enables the simultaneous connection of working pressure gauges and control instruments to the pressure installation, ensuring safe isolation of measuring circuits from the process medium.

The valve design allows for precise control of the medium flow and safe disconnection of measuring instruments without the need to drain the entire installation. This makes it possible to perform calibration, replacement, or maintenance of pressure gauges during system operation.

Materials and corrosion resistance

The valve body is made of 1.4571 stainless steel, which is characterized by high resistance to aggressive media and intergranular corrosion. This type of austenitic steel contains molybdenum and titanium additives, which significantly increases the durability of the construction in environments with increased humidity and the presence of chlorides.

The seal is made of PTFE (polytetrafluoroethylene), a material with exceptional chemical inertness and a wide operating temperature range. PTFE does not react with most chemical substances, maintains its mechanical properties at temperatures from -200°C to +260°C, and does not age under the influence of UV radiation.

Operating parameters and operational safety

The device operates in a medium temperature range from -40°C to +200°C, enabling its use in both refrigeration applications and high-temperature industrial processes. The maximum working pressure is PN 400 bar, allowing for operation in high-pressure systems typical for the mechanical engineering, energy, or petrochemical industries.

The design complies with the requirements of the DIN 16270 standard, ensuring compatibility with international industrial installation standards. The valve features form A with a mounting fitting that allows for easy installation in piping installations of various diameters.

Industrial applications and system compatibility

The valve finds wide application in the hydraulic systems of industrial machines, energy installations, and laboratory applications requiring precise pressure measurements. It is particularly recommended for installations where frequent calibration or replacement of measuring instruments is necessary.

The M20 x 1,5 external connection with a mounting fitting ensures universal compatibility with most standard pressure gauges and pressure transmitters available on the European market. The M20x1,5 metric thread is a widely used standard in the hydraulic and pneumatic industry.

The compact design allows for inline mounting without additional intermediate elements, reducing the number of potential leak points and minimizing the dead volume in the hydraulic system.
