Coliter ® Multi-Function Sleeve Valve with Thermometer Port – PN16
QF5207 Multi-Function Prefabricated Sleeve Valve – Dual Outlet with Thermometer Port
The Coliter® QF5207 Multi-Function Prefabricated Sleeve Valve is an integrated lead-free brass valve designed for heating, HVAC, and advanced plumbing systems that require combined flow control, temperature monitoring, and auxiliary connections. It features a full-port ball valve body with two functional side outlets: one equipped with a dedicated thermowell port for thermometer or temperature sensor insertion, and another for a pressure gauge, water meter, or system drain. This intelligent prefabricated design reduces installation time, minimizes potential leak points, and enables real-time system diagnostics without additional fittings. Constructed from high-quality forged brass with a chrome-plated ball and PTFE seats, it ensures reliable bubble-tight shut-off and smooth operation. Rated at PN16 (1.6 MPa) and suitable for water within a temperature range of 0°C to 90°C, the QF5207 complies with GB/T 17241 and relevant potable water safety standards. Ideal for boiler inlets, heat exchangers, solar thermal systems, district heating substations, and energy-efficient building services.
