Pressure differential controller STAP DN 40 - 1/2 inch, range 20-80 kPa 52265040

Differential pressure regulator – precise control in installations

This STAP DN 40 differential pressure regulator is a reliable solution for maintaining stable pressure in heating and water systems. Designed for use in 1 ½ inch diameter installations, it provides precise regulation and optimal system performance. Its robust construction and manual adjustment capability make it an ideal choice for both professional installers and end users.

Functionality and application

The STAP DN 40 regulator is designed to maintain a constant differential pressure, regardless of flow changes. This ensures even distribution of heat or water throughout the installation. Membrane control guarantees accurate operation, and the closing model allows for easy servicing and maintenance. Equipped with an impulse tube, it enables precise pressure measurement. The ability to set the differential pressure in the range of 20-80 kPa allows the regulator to be adapted to the specific needs of the installation. A Kvs value of 12.8 indicates its efficiency and ability to flow liquids.

Construction and characteristic features

The regulator is made of materials ensuring durability and corrosion resistance. It has internal gas parallel threads (BSPP) on both side 1 and side 2, which facilitates installation and integration with the existing installation. Its height of 181 mm allows for easy adaptation to limited space. Pressure class PN 16 ensures safe operation even at higher working pressures. The lack of a flow limiter and drain makes the regulator versatile in application, and the lack of fittings simplifies installation. The raw finish allows for adaptation of the appearance to the surroundings or protection against corrosion by appropriate painting or coating. The maximum differential pressure of the regulator is 250 kPa.
