## Summary description

B\_METERS BKM 3/4 shut-off valve with integrated check valve and union nut (MPN BKM20). Designed to stop flow and prevent backflow in water piping systems. Suitable for domestic and light commercial installations where reliable isolation and backflow prevention are required. Compatible with 3/4" connections and intended for inline installation in supply lines.

## Long description

The B\_METERS BKM 3/4 shut-off valve with integrated check valve and union nut is a compact inline valve designed to stop water flow and prevent backflow in supply lines. Intended for use with 3/4" connections, this valve combines isolation and non-return functions in a single fitting to simplify installation and reduce the number of components in domestic and light commercial plumbing systems.
Advantages
This valve provides reliable shut-off capability together with an internal check mechanism that prevents reverse flow, helping to protect fixtures and piping from contamination and pressure backflow. The union nut allows easier removal and replacement without disturbing adjacent pipework, reducing service time. Constructed for compatibility with standard 3/4" supply connections, it is suitable for straightforward inline installation and routine maintenance.
Suitable for
 Domestic water supply lines (kitchens, bathrooms)
 Light commercial plumbing and service connections
 Hot and cold water distribution systems
 Inline isolation and backflow prevention for appliances (e.g., water heaters, pressure tanks)
Key specifications
 Connection size: 3/4" compatible inline connections
 Function: Shut-off (isolation) combined with integrated check (non-return) valve
 Fitting type: Inline valve with union nut for easy disassembly
 Application: Domestic and light commercial water systems
 Installation orientation: Inline horizontal or vertical piping (follow manufacturer's installation guidance)
How to use
Install the valve in the supply line at the required isolation point, ensuring the flow direction matches the check valve orientation. Tighten the union nut to secure the connection and test for leaks at working pressure before putting the system into regular use. To isolate a section of piping, rotate the valve handle to the closed position; to restore flow, open the valve fully. For removal or replacement, loosen the union nut to detach the valve without cutting the pipe.
Usage recommendations
Use compatible sealing materials and follow local plumbing codes during installation. Periodically inspect the valve for leaks and proper operation; exercise the shut-off occasionally to prevent seizing. If used with hot water, verify temperature limits in the technical documentation and ensure materials are suitable for the intended operating temperature and pressure.
