상품 특징

• ✅Dual Check Valve Design: Incorporates two independently operating spring-loaded check valves to prevent both backpressure and backsiphonage backflow. During normal forward flow, both valves remain open to minimize pressure loss. In the event of reverse flow, the valves close sequentially to provide reliable protection for plumbing and water distribution systems.
• ✅Easy Maintenance Design: Designed for quick service without removing the valve body from the pipeline. Internal components can be removed and replaced as a complete unit, allowing maintenance to be performed by a single technician. This double check backflow preventer helps simplify servicing, reduce labor costs, and minimize system downtime.
• ✅Corrosion-Resistant Materials: Designed for demanding outdoor applications, this irrigation backflow preventer combines a cast bronze valve body, UV-resistant nylon housing, and stainless steel hardware to deliver dependable performance and long service life.
• ✅High-Pressure Seal: Equipped with high-performance silicone and nitrile rubber sealing components for dependable performance. Tested at 350 PSI before shipment, this 3/4 inch backflow preventer is rated for continuous operation up to 175 PSI and helps minimize leakage under changing pressure conditions.
• ✅Versatile Use: This backflow valve supports standard vertical installation and is adaptable to a variety of indoor and outdoor locations. Ideal for residential irrigation systems, commercial landscaping, golf course irrigation, swimming pool fill lines, and other low-hazard non-potable water applications.
