Reliable One-Way Flow Control: Ensures liquid flows in a single direction, optimizing the performance of your water pump system Durable PVC Construction: Designed with high-quality PVC material that withstands prolonged exposure to water, ensuring longevity and reliability Efficient Liquid Retention: Prevents backflow when the pump stops, keeping the suction line filled for quick and easy restarts Low Pressure Functionality: Specifically engineered for low pressure applications, making it ideal for various fluid machine setups Versatile Compatibility: Perfectly suited for 1.5in suction lines, ensuring seamless integration with most standard water pump systems Features: 1. The bottom valve, also known as the check valve, is a low pressure flat valve. 2. The pump ensures that the liquid flows in one direction in the suction line, allowing the pump to work properly. 3. When the pump stops working intermittently, the liquid cannot return to the water source tank, and the suction pipe remains filled with liquid to facilitate pump restart. 4. Made from PVC material that can withstand long-term exposure to water. 5. Professionally and practically designed for reliable performance.
