APOLLO VALVES 4ALF203A2F Reduced Pressure Zone Backflow Preventer

Apollo Valves 4ALF203A2F reduced pressure zone backflow preventer protects water supplies from contamination. It prevents the reverse flow of potentially harmful substances into the clean water system. This valve is useful in healthcare facilities, chemical processing plants and food manufacturing facilities to prevent the backflow of pollutants, chemicals or pathogens into their water systems.

Working Mechanism:

• When water flows into the backflow preventer, it enters through the inlet and passes through the first check valve.
• After passing through the first check valve, the water encounters a zone of reduced pressure created by a pressure relief valve.
• The water is then routed through a second check valve, ensuring that it can only flow in one direction, preventing backflow.
• If the system's pressure drops, the pressure-relief valve opens, allowing water to discharge from the low-pressure zone.

Features:

• Apollo Valves 4ALF203A2F backflow preventer has a straight valve configuration for ease of installation.
• It comes with SAE threaded end connections, ensuring secure fittings.
• This backflow preventer includes a modular captured spring relief valve for efficient pressure regulation.
• It further features a check valve cartridge to prevent backflow contamination.
• This Apollo backflow preventer has a top-mounted test cock for convenient testing and maintenance.
• It features an internal sensing passage for accurate pressure monitoring.
• Apollo Valves 4ALF203A2F backflow preventer includes a bronze cap for durability and corrosion resistance.
• It features a chloramine-resistant EPDM O-ring seal for leak-proof connections.
• Apollo Valves 4ALF203A2F backflow preventer is lead-free and safe for use in drinking water systems.

Frequently Asked Questions:

Q. How do I know if my Apollo 4ALF203A2F backflow preventer is operating correctly?

A. Regular visual inspections can help identify any visible signs of damage or malfunction, such as leaks, corrosion or debris accumulation. Additionally, annual testing by a certified professional is essential to ensure proper operation and compliance with safety standards.

Q. What are some common maintenance tasks for a backflow preventer?

A. Routine maintenance tasks include cleaning and lubricating valves, inspecting for leaks or damage, testing pressure levels and replacing worn-out parts as needed. For more information, check out our comprehensive guide on backflow preventers.

Q. What are the consequences of not using a reduced pressure zone backflow preventer?

A. Without an RPZ backflow preventer, there is a risk of contamination of clean water supplies, which can lead to serious health hazards, legal liabilities and damage to equipment and infrastructure.

Q. What steps should I take if I suspect backflow contamination in my water system?

A. If you suspect backflow contamination in your water system, immediately shut off the water supply to prevent further contamination and potential health risks.

Q. Are there any precautions I should take when restarting my water system after maintenance or repairs on the backflow preventer?

A.

• Slowly open the water supply valves to restore water flow & pressure gradually.
• Monitor for any unusual fluctuations / leaks and conduct functional checks to verify that the backflow preventer is operating correctly before resuming normal operations.
