Priority valve DH300, DN80 DH300-80A

Priority valve for industrial and commercial installations

The DH300 valve is a reliable solution for pressure regulation in installations, especially where maintaining constant pressure on the inlet side is required. It is suitable for anywhere where it is necessary to limit the pressure in the supply network or on the section supplying customers with the highest requirements. Its compact design allows for installation even in places with limited space, e.g. in ducts.

The valve is made of spheroidal graphite cast iron GGG40, which ensures durability and corrosion resistance. It is designed to work with liquid, including drinking water, at a maximum temperature of 80°C and a working pressure of up to 16 bar. The flanged connection with a diameter of DN80 facilitates integration with existing infrastructure.

Application and benefits:

• Pressure regulation: Maintains constant pressure on the inlet side, protecting devices from damage caused by excessive pressure.
• Flow limitation: Can be used to limit flow in the installation.
• Wide application: Ideal for industrial and commercial installations where precise pressure control is required.
• Durability and resistance: Made of high-quality spheroidal graphite cast iron GGG40 ensures long-lasting and reliable operation.
• Built-in filter: Has a built-in water filter that protects the valve and installation from contaminants.
• No power supply required: The valve does not require an external power source, which simplifies installation and reduces operating costs.
• Precision regulation: Provides high regulation accuracy even with variable inlet pressures and small flows.

The DH300 valve meets the BSEN 1567 standard, which confirms its compliance with European safety and quality standards. Thanks to the powder coating both inside and outside, it is corrosion resistant and environmentally friendly – the powder is physiologically and toxicologically safe. The high Kvs coefficient (103) guarantees a large flow while maintaining precise pressure regulation with an opening pressure range of 3-15 bar. The minimum inlet pressure for proper valve operation is 0.5 bar.
