Check Valve – Reliable Protection for Installations

This check valve, with a diameter of DN125 and pressure rating PN25, combines the functions of a check valve and a shut-off valve. It provides effective protection against backflow of the medium and enables complete flow isolation. The valve design allows for easy maintenance and precise control over the medium in the system.

Valves of this type are distinguished by cylindrical, smooth stem surfaces, setting them apart from standard gate valves. Different constructions offer various materials for the closing disc, tailored to specific operating conditions and medium types.

Construction and Materials

The valve is manufactured from high-quality materials ensuring durability and reliability:

• Body: Ductile iron (EN-GJS-400-18-LT 5.3103), providing high pressure resistance and corrosion protection.
• Disc and Seat Ring: Bronze – wear- and corrosion-resistant material ensuring tight sealing.
• Stem: Brass – ensures smooth valve operation and corrosion resistance.
• Construction: Spring-loaded free disc – design enables rapid and reliable closure of flow.

This material selection ensures long service life even under demanding operating conditions.

Application and Installation

The valve with flanged connections is designed for use in various industrial and building installations. It performs reliably in water, heating, and other systems transporting media that are non-corrosive to the construction materials. Note that not all applications are suitable for every material configuration – it is recommended to consult the system specifications before selecting the appropriate valve. Installation follows standard flanged valve procedures and must be performed by a qualified installer in accordance with applicable standards and regulations.
