Product Overview
The Siemens VXP45.20-4 is a three-port seat valve engineered for precise control of fluid and gas flow in industrial process and pneumatic systems. Operating on a direct-seated, pressure-balanced poppet principle, this valve provides tight shut-off and reliable switching between two outlet ports from a single inlet port. Its robust brass and stainless steel construction makes it suitable for demanding process environments where leak-tight sealing and repeatable actuation are critical. The VXP45.20-4 is commonly deployed as a control or changeover valve in building automation, industrial process lines, and pneumatic control circuits.
