Shut-off and setting valve STK for consumers, DN15 50007715

Shut-off and balancing valve STK is a reliable solution for precise regulation and complete shut-off of flow in heating, cooling and domestic hot water systems. Its versatility makes it a popular choice among professional installers and end-users looking for effective temperature control in their homes.

Functionality and application

The STK valve combines two key functions: shut-off and flow regulation. This allows not only quick shut-off of the medium supply but also precise adjustment of the amount of heat or cooling to current needs. A Kvs value of 1.8 ensures optimal flow for installations with a nominal diameter of 1/2 inch (DN15). This makes the valve perfect for systems powered by central heating water (CH). Made of high-quality materials, such as AMETAL®, it guarantees long-lasting and trouble-free operation.

Construction and characteristic features

The STK valve is characterized by a solid construction and thoughtful design. It has tapered internal gas threads (BSPT) on both sides, which facilitates installation and ensures the tightness of connections. The nickel-plated surface protects against corrosion and external factors, increasing its durability. A position indicator allows easy reading of the valve status – open or closed – without having to check by hand. Additionally, the valve has a pressure class of PN 20, which means it is adapted to work in installations with increased pressure. The lack of measuring ports simplifies installation in standard installations.
