Apollo 4A Series Pressure Vacuum Breaker Assembly | 3/4 in. & 1 in.
Product Overview
The Apollo 4A Series pressure vacuum breaker assembly is designed to help protect a potable water supply from backsiphonage in applications where this type of backflow protection is approved. It is commonly installed on irrigation or other water lines that can be exposed to a loss of supply pressure, which may otherwise allow downstream water to be drawn backward toward the potable system. The internal air-inlet and check components respond to changing pressure conditions to interrupt that reverse siphoning path.
This product listing includes 3/4 in. and 1 in. FIP models with shut-off valves and test cocks for isolation, testing, and service. A pressure vacuum breaker does not provide backpressure protection, so the hazard type and system layout must be evaluated before selection. Installation height, vertical orientation, drainage, testing access, and freeze protection must follow local requirements.
Key Features:
- Pressure vacuum breaker for approved backsiphonage protection
- 3/4 in. and 1 in. sizes
- FIP threaded connections
- Top-entry service access
- Shut-off valves and test cocks included
- Stainless steel handles and nuts
Common Uses:
- Landscape irrigation systems
- Approved hose or wash-down applications
- Potable water supply protection where a PVB is permitted
- Replacement of compatible PVB assemblies
Technical Specifications:
- Models: 4A504A2F, 4A505A2F
- Sizes: 3/4 in. and 1 in.
- Connections: FIP
- Maximum Pressure: 150 PSI
- Temperature Range: 33-140°F
- Approvals: ASSE 1020, CSA B64.1.2, IAPMO listed
Compatibility and Installation Notes:
Install vertically at the required elevation above downstream outlets. Confirm the hazard type, local approval, testing rules, drainage, and freeze-protection requirements.
FAQ:
Does a PVB protect against backpressure?
No. It is intended for approved backsiphonage protection.
Are shut-off valves included?
Yes. These A2F assemblies include shut-off valves and test cocks.
