Pressure differential controller STAP DN 20, range 5-25 kPa 52265120

Differential pressure regulator – precise control in heating and cooling systems

The STAP DN 20 differential pressure regulator is a component designed to maintain a constant differential pressure in heating and cooling systems. This device ensures stable regulation, minimizing the risk of noise and system malfunction. Thanks to the ability to precisely set the adjustment range, the STAP regulator is suitable for both new installations and the modernization of existing ones.

Application and functionality

The STAP regulator is particularly useful in systems with thermostatic valves, where stabilization of the differential pressure allows for optimal utilization of the potential of each radiator. This makes it possible to achieve thermal comfort while simultaneously reducing operating costs. The device is used in installations powered by water, glycol or other liquids not containing solid particles. The body made of bronze ensures durability and corrosion resistance.

Key features and benefits

• Precise regulation: Adjustment range of 5-25 kPa allows adaptation to specific operating conditions of the installation.
• Stable operation: Maintaining a constant differential pressure ensures efficient operation of the entire heating or cooling system.
• Durability and reliability: The use of high-quality materials, such as bronze and stainless steel spring, guarantees a long service life of the device.
• Ease of use: Handwheel enables intuitive and precise adjustment of operating parameters.
• Compatibility: The regulator has tapered BSPT-Rc internal gas threads (ISO 7-1 / EN 10226-1) which facilitates integration with existing infrastructure.
• Possibility of cooperation with STAD valves: In combination with the STAD valve, it enables accurate flow measurement and optimization of the entire system.
• High Kvs value: Kvs value at 3.1 ensures adequate medium flow in the installation.

Technical specifications

The STAP DN 20 regulator is characterized by a pressure class of PN 16 and a maximum differential pressure of 250 kPa at a temperature of 20°C. It has membrane control and an impulse tube, which enables precise measurement and control of operating parameters. The device is adapted to work at temperatures from -20°C to +120°C. The lack of a drain and shut-off valve does not negatively affect its functionality in typical applications. The height of the regulator is 139 mm, which facilitates installation even in tight spaces.
