The Vogiran straight spring check valve PN16 features a ductile iron GGG40 or carbon steel body, designed for a nominal pressure of 16 bar. It employs a spring-loaded disc mechanism that opens with forward flow and closes rapidly to prevent backflow. Internal components, including the disc, spring, and seat, are stainless steel for high corrosion and wear resistance, with an operating temperature range of 0°C to 200°C. The internal sealing uses EPDM or NBR elastomers to minimize leakage. Its straight flow path reduces pressure drop and ensures silent operation in horizontal and vertical pipelines. Manufactured in accordance with DIN 3202 and EN 12266 standards, it is suitable for water, steam, air, and industrial oils.
Depending on nominal size DN15–DN200, the valve weight ranges from 3 to 40 kilograms, with flanges designed per EN1092-2 standards. The internal surfaces are epoxy-coated for superior corrosion and humidity resistance, extending service life. Its robust construction and engineered design enable quick installation and easy maintenance. The Vogiran PN16 straight spring check valve delivers reliable operation, tight sealing, and long-lasting performance, making it a professional choice for industrial pipelines and thermal installations.

To quickly detect leakage in a PN16 WEG Iran flat-seat check valve, first reduce or shut off system flow to control internal pressure. Visual inspection of the body and flange area for droplets or moisture is the initial step. Applying a soap solution or leak-detecting fluid on connections and seals can reveal minor leaks. Pressure testing with a manometer and comparing inlet and outlet pressures also indicates proper valve function. Performing these checks periodically prevents pipeline damage, enhances system safety, and reduces maintenance costs.
