Pressure differential controller STAP DN 40 - 1/2 inch, range 10-40 kPa 52265140

Differential pressure regulator – precision and stability in your system

This differential pressure regulator, with a nominal diameter of 1 1/2 inch (DN 40), is a key component in heating and cooling systems where precise pressure control is required. The device maintains a constant, adjustable differential pressure at a given flow rate, which translates to more efficient and quieter operation of the installation. This minimizes the risk of noise generated by control valves.

Functionality and application

The STAP regulator is designed to operate in heating and cooling installations where stabilization of the differential pressure is crucial for the optimal operation of the entire system. Its operation is based on precise flow control, which allows for even distribution of heat or cold throughout the facility. This solution also facilitates the hydraulic balancing and technical start-up of the installation. Compact dimensions (height 181 mm) allow for installation even in tight spaces.

Construction and operating parameters

The device has internal gas parallel (BSPP) threads on both side 1 and side 2 connections, ensuring easy integration with existing infrastructure. Control is performed using a handwheel, allowing precise setting of the desired differential pressure in the range of 10 to 40 kPa. The Kvs value is 12.8, indicating a high flow rate of the regulator. The pressure class PN 16 guarantees the safety and reliability of the device at a maximum differential pressure of 250 kPa. Additionally, the regulator is equipped with an impulse tube for pressure measurement and the ability to shut off the flow. The surface protection is in a raw state.
