unloading relief valve - 0.1 - 24 gpm (0.3 - 90.84 l/min) | PRESSUREMATIC™


Unlike other relief valves, the Pressurematic™ is specially designed to maintain constant pressure at its inlet over its entire operating flow range. This makes the Pressurematic™ ideal in positive displacement pump applications where line flow may vary with time, but constant fluid pressure is critical.
The Pressurematic™ is not a normal pressure regulator. Rather than reacting to fluid...
