Coliter ® Brass Ball Valve with Filter – Lead-Free, PN16, Integrated Strainer
QF5302 Brass Ball Valve with Filter – Integrated Strainer for Clean Water Systems
The Coliter® QF5302 Brass Ball Valve with Filter is a lead-free, full-port ball valve featuring an integrated in-line strainer (filter) to protect downstream components—such as water meters, thermostatic valves, and pumps—from sediment, sand, and pipe debris. The filter basket is easily accessible for cleaning: simply close the ball valve, unscrew the filter cap, and remove contaminants without disconnecting the pipeline. Constructed from forged brass with a chrome-plated ball and PTFE seats, it ensures reliable bubble-tight shut-off and smooth quarter-turn operation. The valve has ISO 228 (BSP) parallel threads and is rated at PN16 (1.6 MPa), suitable for water, non-corrosive liquids, and saturated steam within a working temperature range of -20°C to 110°C. Compliant with WRAS and ACS standards, the QF5302 is ideal for residential water inlets, heating systems, irrigation lines, and utility connections where system cleanliness and long-term reliability are critical.
