Pressure differential controller STAP DN 25 - 1/2 inch, range 10-60 kPa 52265025

Differential pressure regulator – precise control in heating and cooling systems

This STAP DN 25 differential pressure regulator, with a nominal diameter of 1 inch (25), is a key component in heating and cooling systems, ensuring stable and accurate maintenance of the set differential pressure. The device is particularly useful where precise flow control, minimization of noise risk, and simplification of hydraulic balancing are required. This ensures efficient operation of the installation and high user comfort.

Application and functionality

The STAP regulator is designed for installation in heating and cooling systems where maintaining a constant differential pressure with variable flow is necessary. This allows for optimal operation of control valves and ensures even distribution of heat or cold throughout the system. The flow shut-off function facilitates operation and servicing of the installation. Additionally, the presence of an impulse tube allows for precise measurement of the differential pressure.

Construction and characteristic features

The regulator is made of high-quality materials, guaranteeing its durability and reliability. It has internal gas parallel (BSPP) threads of 1/2 inch on both connection side 1 and 2, which facilitates integration with existing infrastructure. The adjustment mechanism is based on a handwheel, which provides intuitive operation and precise setting of the desired differential pressure in the range of 10 to 60 kPa. The pressure class of the device is PN 16, and the maximum differential pressure is 250 kPa. The Kvs value of the regulator is 5.5, which affects its performance in various operating conditions. The use of a stainless steel spring ensures corrosion resistance and long-term maintenance of regulatory properties.
