Pressure reducing and safety valve Prescor PRV PN25 1.0–6.0 bar R1" 27462

The Prescor PRV pressure-reducing and safety valve is a reliable solution for precise pressure reduction and stabilization in installations. Designed to operate with water as well as water-glycol mixtures (up to 50% concentration), it performs reliably in both heating systems and other applications requiring controlled pressure. Constructed from dezincification-resistant (DZR) brass, it ensures durability and corrosion resistance, resulting in extended service life.

Construction and Application

This valve, with a nominal diameter DN20 and threaded connection 1", is rated for a maximum working pressure of PN25. Its spring-operated design allows precise setting of the outlet pressure within a range of 1 to 6 bar, with a factory preset of 3 bar. This enables installers to easily adapt the valve to the specific requirements of the installation. The pressure-reducing and safety valve protects system components from excessive pressure, ensuring safe and efficient operation.

Key Features and Benefits

• Precise Regulation: Adjustable range from 1 to 6 bar allows accurate pressure matching to system requirements.

• Durability and Corrosion Resistance: Housing made of dezincification-resistant (DZR) brass guarantees long service life and resistance to corrosion.

• Safety Function: Integrated safety valve protects the system against pressure exceeding allowable limits.

• Versatility: Compatible with water-glycol mixtures (up to 50%), expanding application possibilities.

• Easy Installation: External tapered gas thread (BSPT-R, ISO 7-1 / EN 10226-1) enables quick and secure installation in existing systems.

• Wide Temperature Range: Medium temperature tolerance up to 80°C allows use in diverse operating conditions.

The Prescor PRV valve is a robust choice for professional installers and end-users seeking a reliable solution for pressure control in heating or water systems. Its compact dimensions (height 149 mm, length 170 mm, working length 136 mm) facilitate installation even in confined spaces.
