Self-sealing drain valve KFE 15SD 301340909

Universal drain valve for various installations

This self-sealing drain valve KFE 15SD is a reliable solution for draining and venting heating, water supply and other systems where effective removal of air or liquids is required. Its versatility makes it suitable for both new installations and modernization of existing ones. The valve is particularly useful in the lowest points of installations where air or sediment accumulates.

Construction and materials – durability and resistance

The valve is made of high-quality brass (CuZn40Pb2 / CW617N), which guarantees its resistance to corrosion and long life even in difficult operating conditions. Brass is a material commonly used in fittings due to its resistance to water and other media. Connections made of a combination of BSPP-G internal and BSPP external threads ensure a tight and secure connection with pipes and other installation elements. Pressure class PN 16 means that the valve is adapted to work at a maximum pressure of 16 bar.

Functionality and benefits for the installer and user

A key feature of this valve is its self-sealing mechanism. This eliminates the risk of dripping after closing, which is particularly important for end users – it ensures comfortable use and no unpleasant surprises. For installers, this means saving time and avoiding the need to re-tighten or repair leaks. In addition, the standard nominal connection diameter of 1/2 inch (DN15) facilitates installation in most typical installations. The valve allows easy draining of parts of the installation during servicing or maintenance, which facilitates troubleshooting and component replacement. Maximum operating temperature up to 110°C expands the range of valve applications.
