Coliter ® Multi-Function Prefabricated Sleeve Valve – QF5052, PN16, Dual Outlet
QF5052 Multi-Function Prefabricated Sleeve Valve – Dual Outlet for Water Meter & Pressure Gauge
The Coliter® QF5052 Multi-Function Prefabricated Sleeve Valve is an integrated lead-free brass valve engineered for efficient water service installations in residential and commercial buildings. It combines a full-port ball valve with two dedicated side ports: one for direct connection to a water meter and another for a pressure gauge or sensor. This all-in-one design eliminates multiple fittings, reduces potential leak points, and streamlines installation. Constructed from high-quality forged brass with a chrome-plated ball and PTFE seats, it ensures bubble-tight shut-off and smooth operation. The valve features ISO 228 (BSP) parallel threads and is rated at PN16 (1.6 MPa), suitable for potable water within a temperature range of 0°C to 90°C. Compliant with GB/T 17241 and relevant drinking water safety standards, the QF5052 is ideal for main water leads, utility risers, and smart metering-ready plumbing systems.
