Pressure Backflow Preventer is an essential device that ensures the safety and integrity of water systems. It prevents contaminated water from flowing back into clean water supplies. This is crucial in protecting public health and water quality. In this guide, we’ll explore the key features, benefits, and applications of the 2-inch Pressure Backflow Preventer.

Key Features of the Pressure Backflow Preventer

1. Size: 2 Inches
   The 2-inch size of this backflow preventer suits various applications. It fits well in both residential and commercial water systems, offering reliable protection while saving space.
2. Max. Working Pressure: 175 psi (12.1 bar)
   With a maximum working pressure of 175 psi (12.1 bar), this device can handle high-pressure environments. It works well in city water systems or industrial settings, where pressure stability is important.
3. Hydrostatic Test Pressure: 350 psi (24.1 bar)
   The hydrostatic test pressure of 350 psi (24.1 bar) ensures that this backflow preventer can withstand extreme conditions. This testing guarantees its durability and long-lasting performance in demanding situations.
4. Temperature Range: 32°F to 140°F (0°C to 60°C)
   The Pressure Backflow Preventer operates within a temperature range of 32°F to 140°F (0°C to 60°C). This feature allows it to perform well in different climates, from colder environments to hotter ones.
5. Valve Body: Lead-Free Cast Copper Silicon Alloy
   The lead-free cast copper silicon alloy valve body ensures long-term durability and safety. This material is corrosion-resistant and meets safety regulations for potable water systems.
6. Elastomers: Silicone
   The silicone elastomers offer excellent sealing properties. They resist degradation over time, ensuring a strong seal and reliable function for years.
7. Springs: Stainless Steel
   The backflow preventer uses stainless steel springs to maintain smooth operation. Stainless steel resists corrosion and ensures the device works in high-humidity or harsh environments.
