Back pressure regulator for ex atmospheres and medium to high flow rates
Self-acting control without pneumatic or electrical elements
Made of high-quality stainless steel with excellent corrosion resistance
Soft-sealed valve cone
Easy adjustment and maintenance with no special tools

The UV 5.1 ATEX H2 Back Pressure Regulator is a self-acting back pressure regulator designed for use in explosive atmospheres (ex atmospheres) and for medium to high flow rates. It is a diaphragm-controlled, spring-loaded proportional regulator with relief, constructed entirely of high-quality stainless steel, ensuring excellent corrosion resistance. This regulator offers accurate pressure control without the need for pneumatic or electrical control elements. It is compliant with the ATEX directive 2014/34/EU and DIN EN ISO 80079-36, featuring a leakage line connection, adjusting screw seal and lock, potential equalization, protected body connections, a grounding lug, and the use of low-spark materials. It is suitable for liquids, gases, and steam, operating within a temperature range of -10°C to +50°C. The regulator has a wide range of Kvs values (3.5-22 m³/h) and is available in various connection sizes (DN 15-50, G 1/2-2).

Use Cases

Valve for ex atmospheres and medium to high flow rates
Used in industrial settings requiring pressure regulation in hazardous areas
Used in systems involving liquids, gases, and steam

Capabilities

Controls upstream pressure in defined setting ranges from 0.02 to 12 bar, depending on spring configuration.
Operates fully self-acting, without external energy.
Handles liquids, gases, and steam up to 130 °C.
Supports DN 15–50 with Kvs values up to 22 m³/h.
Designed for easy maintenance and reconfiguration via modular spring/diaphragm assembly.
