Water pressure relief valve FP-430-59

for liquidsfire protectionANSI B2.1

Overview
The BERMAD FP-430-59 combines fire pump pressure relief with an electric pre-opening override to anticipate pump start-up surge. On pump start the electric override opens the valve fully; during normal operation the unit functions as a pressure relief valve designed for high-capacity fire pump systems.

Key features & benefits

• Pre-opening preempts pump start-up surge to reduce transient overpressure
• Electric override provides full opening at pump start and allows continued pressure relief operation
• Simple, time-proven design with fail-safe actuation
• Single-piece elastomeric diaphragm seal (VRSD technology) for reliable sealing
• Obstacle-free, uninterrupted flow path with no mechanical moving parts in main flow
• Optional valve position limit switches for remote indication
• In-line serviceable design for fast, easy maintenance and cover removal

Typical applications

• Fire pump pressure relief for high-capacity installations
• Foam concentrate recirculation
• Surge prevention at pump start-up
