Balancing valve set STAD PN16 / differential pressure regulator STAP DN 40, range 20-80 kPa 52865006

Differential pressure regulators and balancing valves – precision and ease of installation

The combination of the STAP differential pressure regulator and the STAD balancing valve is a comprehensive solution for effective hydraulic balancing of heating and cooling systems. Combining these two components simplifies system start-up, minimizes the risk of noise generation in regulating valves, and ensures optimal operating parameters. The set is particularly useful in installations with thermostatic valves, where precise maintenance of the differential pressure is crucial for user comfort.

The STAD balancing valve is characterized by a digital knob, allowing accurate adjustment and flow measurement. The STAP differential pressure regulator maintains a constant differential pressure on the circuit, regardless of load changes. Both valves are made of AMETAL® – an alloy resistant to dezincification, which guarantees long-lasting and trouble-free operation, minimizing the risk of leaks. Therefore, investing in this set is a guarantee of peace of mind and reliability for years to come.

Design features and application

The STAP/STAD set is used in heating and cooling installations where precise flow control and maintenance of constant differential pressure are required. The STAP regulator stabilizes ΔpL (differential pressure), and the STAD valve allows flow measurement and complete shut-off of the medium. The measurement port with an optional drain facilitates the hydraulic balancing procedure and diagnosis of any problems. The set is compatible with internal threads compliant with ISO 228 (BSPT) standard, which simplifies installation in existing systems.

Benefits for the installer and user

• Easier start-up: Using the set significantly simplifies the installation start-up process, eliminating the need for time-consuming manual flow adjustment.
• Quiet operation: Precise maintenance of the differential pressure minimizes the risk of noise generation in regulating valves, ensuring acoustic comfort.
• Accurate regulation: The pressure-relieved poppet in the STAD valve ensures accurate pressure regulation, which translates into optimal system performance.
• High measurement accuracy: The measurement port allows precise measurement of flow and differential pressure, facilitating troubleshooting and installation optimization.
• Durability: Construction from AMETAL® material guarantees long-lasting and trouble-free operation of the set, minimizing operating costs.
• Versatility: The set is available in various diameters (DN 40) and adjustment ranges (20-80 kPa), allowing it to be adapted to the specifics of each installation.
• Shut-off function: Easily accessible full shut-off function allows quick flow shut-off if servicing or repair is required.
• Impulse tube included: The set includes a 1 m impulse tube with appropriate fittings, eliminating the need to purchase additional elements.

The STAD PN16 balancing valve / STAP DN 40 differential pressure regulator set is an investment in the comfort, efficiency and reliability of a heating or cooling system. Thanks to precise regulation, ease of installation and high-quality workmanship, it is an ideal solution for both professional installers and demanding end-users.
