SVA – SS Shut-off valves

The Danfoss SVA-S/L SS shut-off valves are essential components in industrial refrigeration systems, particularly in demanding environments where high surface protection is required to combat corrosion and ensure safety. These valves are specifically designed for use in applications such as outdoor installations, coastal environments, and areas exposed to corrosive atmospheres. In addition, they meet the food safety standards that often necessitate daily treatment with detergents to prevent bacterial growth, thus reinforcing the need for robust, corrosion-resistant solutions.

These valves are available in both angleway and straightway configurations, with a range of connection types, including Butt-weld DIN, Butt-weld ANSI, and Socket Weld. The SVA-S/L SS valves are compatible with refrigerants ammonia (R717), CO₂ (R744), and flammable refrigerants, making them versatile for different applications across industrial refrigeration systems.

The design of the SVA-S/L SS valves ensures efficient flow characteristics while maintaining a high level of operational reliability. They are easy to disassemble and service, allowing for quick inspection and maintenance when required. The valve cone is specifically engineered to ensure perfect closure, providing tight shut-off under pressure and preventing leaks in the system.

The valves also feature internal backseating, which allows for the replacement of the spindle seal while the valve is still under pressure, minimizing downtime during maintenance. Furthermore, these valves are constructed from stainless steel that has been approved for low-temperature operations, ensuring they remain reliable and durable even in extreme conditions.
