The 1 in. UPVC non-return valve features a spherical ball inside its body, allowing flow in one direction while blocking back-flow. Constructed with clear UPVC (with a slight blue tint), it has a full bore design for maximum water flow, paired with EPDM O-rings and PTFE seats for durability. The double union ends enable easy disassembly for cleaning and maintenance, making it suitable for commercial plumbing, aquariums, irrigation, and OEM applications. Its smooth inner wall minimizes fluid resistance and prevents dirt buildup, while excellent weather resistance and resistance to bacteria and fungi enhance long-term performance. Designed for vertical installation in an upflow position, the valve must be aligned with the flow arrow to operate correctly, ensuring reliable one-way flow control. Material: Polyvinyl Chloride (PVC).
