Priority valve BERMAD 730, DN100 WW-4"-730 -LE

Priority valve – reliability and installation protection

The BERMAD 730 priority valve, with a nominal diameter of DN100 and a pressure class of PN16, is a key element in water access protection systems, especially in the context of fire protection installations. Its task is to ensure priority access to water for firefighting purposes, guaranteeing an adequate amount and pressure even during simultaneous water consumption for other needs. The valve's design, based on proven hydraulic technology, ensures reliable, fully automatic operation.

BERMAD valves stand out in the market with an exceptionally high Kv coefficient, which translates to minimal flow loss and laminar fluid flow. This feature is particularly appreciated by installers, as it allows for optimization of system efficiency and reduction of operating costs. Additionally, the valve is characterized by ease of adjustment and high reliability – key features for the long-term and trouble-free operation of the installation.

Construction and application

The 730 valve is made of high-quality GGG 40 cast iron, which ensures its strength and corrosion resistance. The membrane made of NBR (nitrile butadiene rubber) guarantees tightness and flexibility over a wide range of temperatures and pressures. The valve design includes an integral wall separating the control chambers, allowing for precise flow control.

This valve finds application in:

• Fire protection installations – ensuring priority access to water for firefighting purposes.
• Water distribution systems – maintaining constant pressure in the water supply network.
• Industrial water installations – protection against the effects of sudden pressure changes.
• Irrigation systems – providing stable pressure in agricultural or horticultural irrigation systems.

Key advantages and design features

• Hydraulic control: The valve operates independently of electrical power, guaranteeing its functionality even in the event of a power failure.
• Anti-cavitation design: Prevents cavitation and noise, extending the valve's life and improving user comfort.
• Configurability: The valve can be configured as single-chamber or double-chamber, adapting it to the specific needs of the installation.
• Ease of adjustment: The simple design allows for quick and precise adjustment of the valve's operating parameters.
• Durable materials: GGG 40 cast iron and NBR membrane ensure long-lasting and trouble-free operation in harsh operating conditions.
• High Kv coefficient: Minimizes flow loss, increasing the efficiency of the water system.
• Release/pressure maintenance function: The valve can perform two separate functions, increasing its versatility.

The BERMAD 730 valve is an investment in the safety and reliability of the water system, which translates into peace of mind for users and optimization of operating costs.
