The Vogiran spring-loaded check valve PN16 is manufactured with a ductile iron body GGG40 and designed for a nominal pressure of 16 bar. It features a vertical design with a spring-loaded disc mechanism that lifts during forward flow and closes instantly when flow stops. Internal components, including the spring, disc, and seat, are made of stainless steel for superior corrosion resistance and operation within a temperature range of 0°C to 200°C. The internal sealing uses metal-to-rubber contact EPDM or NBR to ensure complete backflow prevention. Its compact structure and low weight allow easy installation in both horizontal and vertical pipelines. Built according to DIN 3202 and EN 12288 standards, it is suitable for water, air, steam, and light oil applications.
Depending on nominal size DN50–DN200, the Vogiran valve weighs between 6 and 45 kilograms. The connection flanges are designed per EN1092-2 standard, and the internal surfaces are epoxy-coated for corrosion protection. The fast-acting spring mechanism eliminates water hammer and ensures reliable performance in pressure-variable systems. With its long service life, easy maintenance, and tight sealing, the Vogiran PN16 spring check valve is a dependable and efficient choice for water supply, thermal systems, and industrial process pipelines.

The PN16 WEG Iran piston check valve is designed to control fluid flow in high-pressure pipelines up to 16 bar. The valve body is made of corrosion-resistant cast iron or steel, and the internal disc is wear-resistant steel capable of withstanding impact and high pressure. The piston design directs flow unidirectionally, preventing backflow and water hammer. Smooth valve operation reduces the need for frequent maintenance. Operational lifespan exceeding 10 years under industrial conditions is ensured with periodic maintenance and proper installation. Pressure and leakage testing according to PN16 standards guarantees safety and efficiency in water, steam, and oil systems.
