Standard design
Alfa Laval Unique SSV ATEX offers one, two or three body options. The valve bodies, plugs, sealing, actuators and clamp rings are all easy to configure. The valve contains two to four functioning ports that can serve as shutoffs and it can be configured as a changeover valve with up to six ports. The valve seat, which joins the two bodies in the changeover version, is built to ensure flexibility. The valve seal’s preset compression design increases their durability and service life. The actuator is designed with clamp rings, and a yoke links it to the valve body. The Alfa Laval Anytime configurator allows you to simply modify it to practically any process need.
Working principle
The Alfa Laval Unique SSV ATEX Standard is a clean, remotely operated, single-seat pneumatic valve designed for use in sanitary environments. The actuator protects process lines from pressure peaks, ensuring smooth operation. An Intrinsically Safe Alfa Laval ThinkTop® Basic can control the valve.
