Adjustable cartridge for differential pressure regulator

(VT.143.N) The automatic differential pressure regulator is designed for maintenance of the fixed differential pressure (ΔPn) in the dynamic mode in two-pipe heating and cooling systems with variable flow rate.

The regulator renders possible maintenance of the fixed differential pressure (ΔPn) between the regulator and the point of connection of the impulse tube, thus limiting the flow of the operating environment through the regulated section.

Replaceable cartridges are an integral part of automatic differential pressure regulators, ensuring regulator adjustment.

The cartridges have a rotating connection cage which makes possible impulse tube placement in the position convenient for installation.

VT.143.G cartridge is designed for adjustable automatic differential pressure regulators VT.043.G and VT.043.D and is available in three sizes: D 20, 40 and 50 mm.
