Priority valve, 3/4 inch TYPE: DH300/DH100-3/4A

Priority valve – reliable installation protection

The DH300/DH100 priority valve is a key component in water systems, ensuring constant pressure and protecting components. The device, made of high-quality dezincification-resistant brass (DZR), guarantees long-lasting and trouble-free operation even in harsh conditions. Its compact design makes it ideal for installation in confined spaces.

This valve is used wherever a stable inlet pressure needs to be maintained, protecting pumps from cavitation and hydraulic shocks. This is particularly important in sanitary and industrial installations where precision and reliability are crucial.

Construction and principle of operation

The valve operates on the principle of maintaining a set pressure at the inlet to the installation. It remains closed until the inlet pressure reaches a set value, after which it opens, reducing it to the desired level. The built-in regulating system with ball valves and a replaceable valve cartridge ensure precise flow control and easy servicing.

The principle of operation is based on a precise pilot valve that controls the water flow and maintains a stable output pressure. The valve design minimizes pressure loss and ensures high flow even under changing operating conditions.

Advantages and benefits

• High regulation accuracy: Provides stable pressure even with variable operating conditions and low flow rates.
• Durable construction: Made of dezincification-resistant brass (DZR) guarantees long-term operation.
• Compact dimensions: Allow installation in tight spaces.
• Replaceable valve cartridge: Facilitates servicing and reduces operating costs.
• Wide pressure adjustment range: Allows adaptation to various installation needs (1.0-12 bar).
• Pump protection: Protects pumps from excessive flow, cavitation and hydraulic shocks.
• Versatility of application: Suitable for sanitary and industrial installations.
• Simple installation: The valve is easy to install and configure, which translates into saving time and labor costs.
• Compliance with standards: The product meets applicable safety and quality standards.

The DH300/DH100 valve is an investment in the reliability and durability of the water system – a solution appreciated by both professional installers and end users.
