Pressure differential controller STAP DN 50 - 1/2 inch, range 20-80 kPa 52265050

Differential pressure regulator – stable operation of the heating and DHW system

The STAP DN 50 differential pressure regulator is a reliable device used to maintain a constant differential pressure in central heating and domestic hot water systems. Its task is to stabilize the pressure, regardless of flow changes, which translates into user comfort and optimal system performance. This is particularly important in buildings with extensive installations, where maintaining uniform pressure is crucial for the proper functioning of all components.

Application and functionality

The device finds wide application in heating and DHW systems, both in residential and commercial buildings. The STAP regulator allows for precise setting of the desired differential pressure in the range of 20-80 kPa, adapting to the specific needs of the installation. This makes it possible to ensure optimal flow of the heater through all radiators or heat nodes, eliminating problems with underheated or overheated rooms. The construction with internal parallel threads (BSPP) facilitates installation and integration with the existing hydraulic infrastructure.

Construction and characteristic features

The STAP regulator is characterized by a solid construction and high quality of workmanship. Made of corrosion-resistant materials, it ensures long-lasting and trouble-free operation. Control is carried out using a convenient handwheel, allowing for precise setting of the desired differential pressure value. It also has an impulse tube for connection to the measuring point, which allows for accurate monitoring of the device's operation. The Kvs value of 24.4 provides adequate flow rate for installations with a nominal diameter of 2 inches (50 mm). The closing model guarantees the possibility of completely cutting off the flow if servicing or maintenance of the installation is required. The pressure class PN 16 indicates its resistance to working pressure up to 16 bar. The height of the regulator is 187 mm, which facilitates its installation in tight spaces.
