Multifunctional valve, differential pressure regulator, AB-PM 15 003Z1402

The AB-PM 15 valve is a multifunctional device that combines the functions of a regulating and differential pressure valve. It is indispensable in heating and air conditioning systems where precise maintenance of differential pressure is crucial for optimal system operation. Made of brass, it ensures durability and corrosion resistance, and its compact dimensions (98 mm height) facilitate installation even in tight spaces.

Functions and application

The AB-PM 15 valve is used for hydraulic balancing of heating and cooling circuits. Thanks to precise flow control, it allows for optimal distribution of heat or cold throughout the system, eliminating problems with underheated or overheated rooms. Control is performed by the medium, which means that the valve reacts to changes in pressure in the installation, automatically adjusting the flow. It also has a position indicator that facilitates visual monitoring of the valve status.

This valve finds application in:

• Central heating systems
• Air conditioning systems
• Heating installations with power distribution
• Circuits supplying radiators and fan coil units
• Systems powered by variable speed pumps

Characteristics and benefits

The AB-PM 15 valve stands out with a number of features that translate into benefits for both installers and end users:

• Precise regulation: Allows accurate setting of the differential pressure, which translates into thermal comfort and energy savings.
• Durable construction: Made of brass guarantees long life and corrosion resistance.
• Easy installation: Compact dimensions and metric external threads (connections 1 and 2) facilitate installation.
• Medium control: Eliminates the need for additional actuators or electrical power.
• With flow limiter: Ensures stable system operation even with varying heat or cold demand.
• Impulse tube: Allows connection of a manometer for measuring differential pressure.
• Shut-off model: Allows complete flow shut-off if servicing or repair of the installation is necessary.
• Pressure class PN 16: Guarantees safe operation at a maximum working pressure of 16 bar.

This valve is compatible with water media with a continuous operating temperature of up to 120°C and a maximum differential pressure of 400 bar. The lack of a measuring connection simplifies installation where continuous monitoring of valve operating parameters is not required. Lack of insulation requires the use of additional thermal insulation in installations exposed to low ambient temperatures.
