What sizes and connections does the PRR01 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).

Can it be used with high-temperature media?

With a seal pot and valve stem extension it can be used up to 250°C. The allowable temperature by seal type and size is given in the Allowable Working Temperature table on the specification page.

What options are available?

Seal pot V1/V2, impulse tube and valve stem extension.

VALVEPARK PRR01 Pressure Reducing Regulator

Model: PRR01

The PRR01 is a self-operated pressure reducing regulator that keeps the downstream pressure at the set value without external power. The valve closes when downstream pressure rises and opens when it falls. Sizes run from 1/2" to 10" (15A ~ 250A), with flange, butt weld (BW) and socket weld (SW) connections.

Features

Self-Operated Downstream Pressure Control: Keeps the downstream pressure constant at the desired level without external power, with stable control even when the upstream pressure changes.
Stable Pressure Regulation Performance: The valve closes when downstream pressure rises and opens when it falls, holding the outlet pressure at the set point.
Reliable Pressure Reducing Solution: The simple structure and automatic operation provide safe, stable and efficient pressure control for various industrial applications.
