Priority valve DH300/DH100, threaded connection, 1 1/2 inch DH300/DH100-11/2A

Priority valve for water installations – reliable pressure maintenance

This priority valve, designated DH300/DH100, is a key component in water systems, ensuring stable pressure at the inlet to the installation. It is particularly useful wherever a constant pressure level is required, regardless of fluctuations in the water supply network. Thanks to its compact design, it is ideal even in places with limited mounting space – both in plumbing and industrial installations.

The valve remains closed until the pressure at the inlet reaches a set value, after which it opens, simultaneously reducing the inlet pressure. This solution protects devices connected to the installation from damage caused by excessive pressure. Thanks to the precise pilot valve, it provides high regulation accuracy even under variable operating conditions.

Construction and materials – durability and reliability

The valve body is made of dezincification-resistant brass (DZR), which guarantees its long-term operation and corrosion resistance. The diaphragm is made of reinforced EPDM rubber, and the seals are made of NBR and EPDM to ensure the tightness and reliability of the connections. The internal regulating system with ball valves further increases the valve's efficiency.

The valve is available in a size of 1 1/2 inch (DN40) with an internal threaded connection. It is worth noting the large flow rate and low weight of the device, which facilitates its installation and servicing. The replaceable valve cartridge allows for quick and easy replacement of worn elements without the need to disassemble the entire structure.

Application and benefits for professionals and users

• Device protection: Stable pressure protects pumps, boilers and other devices from damage caused by fluctuations in the water supply network.
• Extended installation life: Maintaining optimal pressure reduces the mechanical loads on installation elements, which translates into a longer life of the entire system.
• Simple installation: The compact design makes installation easier even in tight spaces.
• Reliability: The use of high-quality materials guarantees long-term and trouble-free operation of the valve.
• Easy maintenance: The replaceable valve cartridge simplifies servicing and repairs.
• Versatility: Can be used in water supply networks, plumbing and industrial installations.
• Precise regulation: High regulation accuracy ensures stable operating conditions of the installation even under variable loads.

The DH300/DH100 valve is a solid solution for anyone who values reliability and durability of a water system – both for professional installers looking for proven components and for end users who care about the comfort and safety of their home or company.
