Coliter ® Multi-Function Prefabricated Sleeve Valve – Compact Body, PN16
QF6223 Multi-Function Prefabricated Sleeve Valve – Compact Body for Meter & Gauge Connections
The Coliter® QF6223 Multi-Function Prefabricated Sleeve Valve is a lead-free brass valve engineered for space-constrained water service applications in residential and commercial buildings. It features a compact body design that minimizes overall length while integrating a full-port ball valve with two essential side outlets: one for direct connection to a water meter and another for a pressure gauge or system drain. This streamlined configuration is ideal for utility closets, apartment risers, under-sink cabinets, or retrofit projects where installation space is limited. Constructed from high-quality forged brass with a chrome-plated ball and PTFE seats, it ensures reliable bubble-tight shut-off and smooth quarter-turn operation. Rated at PN16 (1.6 MPa) and suitable for potable water within a temperature range of 0°C to 90°C, the QF6223 complies with GB/T 17241 and relevant drinking water safety standards. With ISO 228 (BSP) parallel threads and available in common sizes such as DN25×32, the QF6223 delivers full functionality in a highly space-efficient package.

Introduction to Brass Valve With Lock
Coliter® provides a specialized range of brass valves with integrated locking mechanisms to prevent unauthorized operation in residential, municipal, and utility applications. The series includes magnetically locked ball valves (e.g., QF6002, QF6213, QF6313) requiring a proprietary magnetic key, mechanically locked models (e.g., QF6327) with slide or pin locks, and multi-lock variants (QF6223) for enhanced security. Many feature built-in Y-strainers or thermometers for added functionality. All are made from lead-free brass, comply with WRAS, ACS, EN, and GB standards, and operate up to PN16 (1.6 MPa) and 100–120°C. Ideal for water meter isolation, rental properties, and public infrastructure—combining tamper-proof control with certified safety for potable water systems.
