FEBCO 765 Pressure Vacuum Breaker, 1 in, Bronze Ball Valves

The FEBCO 765 Pressure Vacuum Breaker (PVB), 1 in nominal, is a bronze-bodied assembly that protects irrigation, cooling, and process systems from back‑siphonage. It combines a check valve and air-opening port in one durable unit and accepts quarter‑turn ball valves for isolation.

• Freeze-sensing compatibility: Built to work with SentryPlus Alert technology; freeze alerts require an add-on connection kit for BMS/IMS or Wi‑Fi integration.
• Rugged construction: All-bronze body with an engineered plastic bonnet to reduce freeze damage and a lightweight poppet that seals the air opening under low-flow conditions.
• Serviceable design: Internal parts are accessible in line from the top of the unit for fast maintenance without pipeline removal.
• Performance: Rated to 150 psi (10.3 bar) with a temperature range of 32°F to 140°F (0°C to 60°C); designed for minimum head loss.
• Installation details: NPT threaded 1 in connections; install at least 12 in above the highest downstream outlet and downstream piping for correct operation.
• Applications: Ideal for irrigation systems, cooling towers, laboratories, pools, and other systems requiring protection against toxic or non‑toxic backsiphonage.

Order FEBCO 765 PVB assemblies when you need proven backflow protection with optional remote freeze alerts. Note: the freeze-sensing function requires the separate connection kit and compatible monitoring system; ball valve shutoffs and test cocks are included for field testing and maintenance.
