How does the PDRC01 work?

It keeps the differential pressure between the inlet and outlet pressure points constant. The valve closes when the differential pressure rises. No external power is required.

What sizes and connections does the PDRC01 offer?

Sizes are 1/2" ~ 10" (15A ~ 250A) with flange, butt weld (BW) and socket weld (SW) connections. The pressure rating is ASME Class 150 ~ 300 (PN16 ~ 40).

VALVEPARK PDRC01 Pressure Differential Regulator (Closing Type)

Model: PDRC01

The PDRC01 is a closing type differential pressure regulator that keeps the differential pressure between the inlet and outlet pressure points constant without external power. The valve closes when the differential pressure rises. Sizes run from 1/2" to 10" (15A ~ 250A), and it suits the direct connection method of district heating systems.

Features

Self-Operated Differential Pressure Control: Maintains a constant differential pressure between the inlet and outlet pressure points without external power, adjusting automatically as system pressure changes.
Suitable for Heating and District Heating Systems: Widely used in city heating systems and large building heating networks, and especially suited to the direct connection method of district heating systems.
Automatic Pressure Stabilization: The valve closes automatically when the differential pressure rises, preventing excessive differential pressure, protecting the piping system and keeping flow conditions stable.
