Features
- Internal or external pressure sensing
- Differential pressure sensing
- Direct pressure gauge installation
- Typical Applications
- Pressure reducing valves sizes 6-12″ (Standard model #2PBL)
- Flow Control Valves sizes 8-16″ (ֺModified to differential sensing #2PBL-DR)
- Closing surge control (additional feature 49) for sizes 10-16″ (Modified to external pressure sensing #2PBL-R)
Description
This is a direct acting valve—actuated by a pressure responsive diaphragm—which tends to reach equilibrium with the set spring force. Fully balanced trim ensures high accuracy and stability.
When used in a pressure reducing circuit, the pilot modulates closed as downstream pressure rises above set point.
