Float valve for cistern DN-15 (1/2") — No name, model 11012181

Float valve for cistern DN-15 (1/2") — model 11012181 by No name is a mechanical inlet valve designed to control water level and automatically refill toilet cisterns. The valve features a compact DN-15 (1/2") threaded connection and a float-operated mechanism that opens and closes the water supply according to tank level. It is intended for replacement or repair of standard cisterns and for use in universal flushing systems where a DN-15 inlet is required.

Advantages

The valve provides reliable mechanical operation without electrical components, making it suitable for long-term use with minimal maintenance. Its compact DN-15 connection enables direct installation in cisterns designed for 1/2" fittings, and the straightforward design supports uncomplicated mounting and adjustment. Constructed from corrosion-resistant materials for contact with potable water, the valve offers stable fill control and consistent shutoff performance.

Suitable for

• Replacement of worn or damaged inlet valves in domestic toilet cisterns
• Maintenance and repair work on universal flushing systems with DN-15 connections
• Plumbing installations requiring a compact mechanical float valve for water level control

Key specifications

• Connection size: DN-15 (1/2") threaded inlet
• Operation: mechanical float-actuated valve
• Usage: toilet cisterns and flushing systems
• Mounting: designed for standard cistern mounting configurations
• Material properties: corrosion-resistant components suitable for potable water contact

How to use

Shut off the water supply before starting replacement. Remove the existing inlet valve from the cistern and inspect the mounting area for debris or damage. Install the DN-15 threaded connection of the new float valve into the cistern inlet and secure according to the cistern manufacturer’s guidance, ensuring a watertight seal. Connect the water supply, open the supply valve, and observe the filling cycle to confirm the float actuates the valve correctly and shuts off at the desired water level. Adjust the float position or valve settings as needed to achieve the correct fill height.

Usage recommendations

Use compatible sealing washers or thread tape on the DN-15 connection to prevent leaks. Periodically check the float mechanism for scale or debris and clean if necessary to maintain reliable operation; avoid using aggressive cleaners that could damage valve components.
