Multifunctional valve, differential pressure regulator, AB-PM 20 003Z1403

The AB-PM 20 valve is a multifunctional device combining the function of a differential pressure regulator. It is designed for precise flow control in installations where maintaining a stable pressure difference is crucial. Made of brass, it ensures durability and corrosion resistance, which is particularly important in demanding operating conditions.

This valve finds application in heating, air conditioning and refrigeration systems, as well as in industrial installations. Its design based on medium control guarantees reliable operation and eliminates the need for additional power sources. The presence of an impulse tube allows for precise measurement of the pressure difference and adjustment of the valve's operation to current system needs.

Construction features and advantages:

• Brass housing: ensures strength and corrosion resistance, translating into a long service life.
• Medium control: eliminates the need for additional power sources, simplifying installation and reducing operating costs.
• Position indicator: facilitates visual control of the valve status and its settings.
• Flow limiter: allows for precise regulation of the amount of flowing medium.
• Pressure class PN 16: ensures safe operation in installations with a maximum working pressure of 16 bar.
• Nominal diameter DN 20: makes the valve suitable for installations with medium flow rates.
• Manual shut-off option: thanks to the use of a manual shut-off made of plastic (included), the valve can be easily isolated from the installation for maintenance or repair.
• Wide operating temperature range (up to 120°C): enables the use of the valve in various temperature conditions.
• Maximum differential pressure 400 bar: allows operation in systems with high requirements regarding pressure difference.

The AB-PM 20 valve is compatible with metric external threads (on both connection side 1 and 2), which facilitates its integration with existing installations. The lack of a measuring connection simplifies the design and reduces costs while maintaining the high functionality of the device. The valve also has a closing model, which increases safety and minimizes the risk of uncontrolled medium flow.
