Coliter ® Multi-Function Prefabricated Sleeve Valve – Extended Body, PN16
QF6327 Multi-Function Prefabricated Sleeve Valve – Extended Body for Meter & Gauge Connections
The Coliter® QF6327 Multi-Function Prefabricated Sleeve Valve is a lead-free brass valve designed for demanding water service applications where space, accessibility, and reliability are critical. It features an extended body configuration that increases the distance between the main flow path and the side connection ports, allowing easier installation and maintenance of water meters, pressure gauges, or sensors—even in congested utility zones. The valve integrates a full-port ball valve with two dedicated side outlets: one for direct water meter connection and another for pressure monitoring or system drainage. Constructed from high-quality forged brass with a chrome-plated ball and PTFE seats, it ensures 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, it complies with GB/T 17241 and relevant drinking water safety standards. With ISO 228 (BSP) parallel threads and available in sizes such as DN25×32, the QF6327 is ideal for residential risers, commercial building services, and smart metering-ready infrastructure.

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.
