A generic 50mm non-return valve (often associated with 50mm or 2-inch plumbing, or contextually paired with 50-liter tanks or air compressors) is a one-way check valve that allows liquid or air to flow in a single direction while automatically closing to prevent backflow.
Key Description & Specifications
• Function: Permits flow in one direction only and immediately seals shut when flow stops or reverses, protecting pumps from reverse-spin damage or stopping air/water from leaking back out.
• Size: 50mm (2-inch) diameter, designed to fit standard 50mm PVC or pressure pipes.
• Materials: Commonly built from durable PVC, dark grey or plastic body types, with internal springs, flaps, or ball mechanisms and EPDM rubber seals.
• Common Applications:
• Water supply and irrigation lines
• Pool pump plumbing to maintain prime
• Aquaponics, fish ponds, and aquaculture setups
• Small pressure vessels or 50L compressor/fluid systems where reverse pressure must be blocked
