How does the PRR02 work?

The valve opens to release excess pressure when upstream pressure exceeds the set pressure and closes when the pressure drops. No external power is required.

What sizes and connections does the PRR02 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).

What options are available?

Seal pot (V1, V2), control pipeline and valve stem extension.

VALVEPARK PRR02 Pressure Relief Regulator

Model: PRR02

The PRR02 is a self-operated pressure relief regulator that keeps the upstream pressure constant at the set value without external power. The valve opens to release excess pressure when upstream pressure exceeds the set value and closes when it drops. Sizes run from 1/2" to 10" (15A ~ 250A).

Features

Self-Operated Upstream Pressure Control: Provides a constant upstream pressure at the desired level without external power, and keeps the set pressure automatically for stable pipeline operation.
Automatic Overpressure Relief: The valve opens automatically to release excess pressure when upstream pressure exceeds the set pressure, and closes when the pressure drops.
Reliable Pipeline Protection: Designed to protect the piping system from overpressure damage, with a balanced valve option, various sealing materials and a wide pressure setting range for demanding industrial applications.
