Pressure reducer 312 compact DN20, G 3/4 inch 0312.20.250

Pressure reduction in installations – reliability and precision

This 312 compact pressure regulator is a compact and efficient solution for regulating pressure in water, air and other installations where maintaining a stable output pressure is required. The use of high-quality materials and a well-thought-out design guarantee long-lasting and trouble-free operation. It is an ideal choice for both professional installers and end-users looking for a reliable solution.

Construction and application

The 312 compact pressure regulator is designed to reduce the pressure of media such as water, compressed air or neutral liquids and gases. It meets the requirements of PN EN 1567, which confirms its compliance with European safety and quality standards. Equipped with a built-in stainless steel mesh filter (0.25mm mesh), it protects the regulating elements from contamination, which translates into a longer device life. The possibility of connecting a pressure gauge on both sides facilitates control and precise setting of the desired output pressure.

• Wide application: ideal for water supply installations, irrigation systems, and in industrial equipment.
• Versatility: can be mounted in any position – there are no restrictions regarding orientation during installation.
• Ease of use: simple adjustment of the output pressure using the adjustment knob. Remember that the input pressure should be 1 bar higher than the set output pressure for proper operation.
• Cartridge replacement: The regulating cartridge can be replaced without disassembling the fitting, which facilitates servicing and maintenance.

Key features and parameters

The regulator is characterized by a solid construction with a body cast from red brass Rg5 and sealing elements made of plastic with high resistance to temperature and aging. This ensures reliable operation even in difficult operating conditions. It is worth noting the output pressure adjustment range from 1.5 to 5.5 bar and the factory setting at 4 bar – this is the optimal setting for most typical applications.

• Connection: internal thread G 3/4 inch – a standard solution ensuring easy installation in existing installations.
• Maximum input pressure: 16 bar – allows the regulator to be used in installations with high working pressure.
• Output pressure adjustment range: 1.5 - 5.5 bar – allows precise adjustment of the pressure to the needs of a specific device or system.
• Maximum operating temperature: 60°C – allows the regulator to be used in installations with elevated medium temperature.
• Flow rate (at v = 2m/s according to PN 1567): 2.3 m³/h - an important parameter when selecting the appropriate regulator size for the installation capacity.
• Flow rate (at v = 3m/s according to DIN 1988): 3.3 m³/h - additional information helpful in the design of hydraulic systems.
