The Alfa Laval Unique SSV Pressure Relief Valve provides a dependable solution for modern hygienic processing. Unlike standard overflow valves, it utilizes a modular architecture that permits configuration as a one- or two-body unit, allowing it to function as a shutoff valve, changeover valve, or in tangential and aseptic configurations. This versatility ensures that regardless of your plant layout, the valve can be tailored to provide the exact relief pressure range required for your specific media and flow rates. This design focuses on maintaining line integrity during unexpected pressure peaks, which is vital for protecting high-value equipment like pumps and plate heat exchangers.

How defined compression seals improve valve durability

A central feature of the Unique SSV platform is the durability of its sealing system. The valve seals are optimized for a long service life through a defined compression design, which prevents the elastomers from being over-stressed during actuation and cleaning. This allows the valve to maintain a tight seal over thousands of cycles while remaining easy to clean. The actuator is connected to the valve body using a robust yoke, and all components are secured with clamp rings for rapid disassembly during maintenance. With the internal surface finished to Ra < 0.8 μm, the valve meets high standards for validated cleaning and hygienic compliance.

Precise pressure control with automated sensing

For operations requiring advanced monitoring, the valve can be equipped with ThinkTop technology. This allows for automated sensing and control, providing real-time feedback on valve position and performance. This integration supports process safety by allowing operators to monitor the pressure relief status remotely. Settings can be adjusted on-site with ease, providing the flexible relief pressure adjustment necessary to react to changing process conditions without replacing hardware. Whether configured as NO or NC, the valve delivers predictable, repeatable performance across a temperature range of -10 °C to +140 °C when fitted with EPDM seals.
