Vogiran anti-water hammer spring check valve PN16

The Vogiran anti-water hammer spring check valve PN16 is designed with a compact ductile iron GGG40 body, rated for a nominal pressure of 16 bar. It features a stainless steel spring-loaded disc mechanism that responds instantly to flow changes, closing smoothly to prevent water hammer effects. Internal components, including the disc, spring, and seat, are made of stainless steel to ensure corrosion resistance and durability at temperatures from 0°C to 200°C. The sealing interface utilizes EPDM or NBR elastomers for complete backflow prevention. Designed according to DIN 3202 and EN 12334 standards, it is suitable for horizontal and vertical installations in systems carrying water, air, or light oil.

Depending on the nominal diameter DN50–DN200, the valve weight ranges from 7 to 50 kilograms, with flanges built per EN1092-2 standards. The aerodynamic flow path minimizes pressure loss and provides silent, vibration-free operation. Its interior epoxy coating offers excellent resistance to corrosion, extending the valve’s lifespan in humid environments. This model is ideal for pump discharge lines, water supply systems, and thermal installations exposed to sudden pressure fluctuations. With its fast-closing spring mechanism, tight sealing, and robust construction, the Vogir

Vogiran spring-loaded check valve PN16

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 in

Vogiran straight spring check valve PN16

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.

flat spring

A flat spring is an elastic element with a rectangular cross section manufactured from alloy steel with a tensile strength of about 1500 to 2100 MPa. The spring is designed with a thickness between 0.2 and 20 millimeters and a width of 5 to 120 millimeters to generate controlled deformation. The manufacturing process includes cold rolling, heat treatment, and edge grinding to improve dimensional stability and fatigue resistance. With an elastic modulus of approximately 210 GPa, the flat spring delivers accurate and stable performance under dynamic loading conditions.

A flat spring is engineered to absorb vibration and transfer force in industrial systems and can withstand bending stresses up to about 1000 MPa. The spring is manufactured with a longitudinal tolerance of less than 0.1 millimeters to maintain precision in mechanical assemblies. Its surface is protected with phosphate or galvanized coating to increase corrosion resistance. The geometric design of the flat spring enables stiffness adjustment in the range of 10 to 500 newtons per millimeter.

316 Non-Magnetic Stainless Steel Spring

316 Non-Magnetic Stainless Steel Spring: A Reliable Choice for Corrosive and Sensitive Environments

The 316 non-magnetic stainless steel spring is one of the most widely used types of metal springs in demanding industrial applications and corrosive environments. These springs are made from grade 316 stainless steel, known for its unique alloy composition that offers exceptional resistance to rust, acids, salt, and moisture. The term "non-magnetic" refers to the low magnetic permeability of this steel, making it ideal for use in electronic and medical equipment.

Compared to springs made from 304 stainless steel or conventional spring steel, 316 non-magnetic stainless steel springs deliver superior performance under harsh conditions. They not only resist corrosion effectively but also maintain their mechanical integrity under temperature fluctuations and high pressure. If you
e looking for a corrosion-resistant spring for aggressive environments, the 316 stainless steel non-magnetic spring is your best choice.
