Coliter ® Multi-Function Prefabricated Sleeve Valve – Extended Body, PN16
TJ1015 Multi-Function Prefabricated Sleeve Valve – Extended Body for Meter & Gauge Connections
The Coliter® TJ1015 Multi-Function Prefabricated Sleeve Valve is a lead-free brass valve designed for high-accessibility water service installations in commercial and residential buildings. It features an extended body configuration that increases the distance between the main flow path and the side ports, allowing easier mounting and servicing of water meters, pressure gauges, or sensors—even in tightly packed 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, the TJ1015 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 TJ1015 is ideal for building risers, district metering points, and smart plumbing infrastructure where long-term maintainability and reliability are essential.

Introduction to Control Valve
The Coliter® TJ1005 and TJ1015 brass thermostatic radiator valves are precision-engineered for hydronic heating systems, enabling accurate flow regulation to maintain consistent room temperatures. The TJ1005 features a manual adjustable knob for user-controlled heat output, while the TJ1015 is a pre-set fixed-flow valve ideal for system balancing in multi-zone installations. Both models use high-quality brass bodies with nickel plating, operate at PN10 (1.0 MPa), and withstand temperatures up to 110°C. Designed with ISO 228 threads and compatible with standard thermostatic heads, they ensure quiet, reliable performance in residential and commercial underfloor heating or radiator circuits—backed by strict quality control and OEM support.
