Berluto DRV350 Reducing Valve - Low Pressure

The Resideo Braukmann D04FM pressure reducing valve is designed to safeguard domestic water systems from excessive supply pressure. This versatile valve is also suitable for industrial and commercial applications, provided they fall within its specified range. By installing the D04FM pressure reducing valve, you can prevent damage caused by over-pressurisation and achieve a reduction in water consumption. The valve maintains a consistent set pressure, even amidst significant fluctuations in inlet pressure. This control over operating pressure not only lowers the risk of flow noise within the system, but it also enhances the overall efficiency of your water installation. The Resideo D04FM pressure reducing valve is ideal for use in domestic, industrial, and commercial settings.

A marine fire-fighting valve is a specialised component installed on board ships as part of the fire main system, which provides seawater to combat fires across the vessel. These valves play a crucial role in controlling, directing, and isolating the water flow to fire hydrants, hoses, monitors, or sprinklers, ensuring the safety and effectiveness of fire-fighting efforts.

Purpose of a Marine Fire-Fighting Valve

• Deliver seawater from the fire pump to designated fire zones.
• Control or isolate sections of the fire main during emergencies.
• Interface with equipment such as fire hoses, foam systems, and water spray nozzles.

We offer a range of fire valves from leading manufacturers. Please get in touch with us to discuss your requirements.
