Pressure relief valve
0.1 - 24 gpm (0.3 - 90.84 l/min) | PRESSUREMATIC™
Varna Products
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 pressure at its output, as a pressure regulator would, the Pressurematic™ reacts to pressure at its input. This is an important characteristic for maintaining line pressure in positive displacement pump systems. This is because the pressurematic will divert excess flow back to the reservoir, preventing pump stall, a line burst, or worse.
Performance:
It can hold the set pressure to within 1psi over it entire working range.
The inlet pressure will only increase after the flow rate has exceeded the Pressurematic's operating limit. For potentially higher flow rates, several Pressurematics can be used in parallel.

Adjustable pressure setting is tamper resistant
Inlet pressure within +/- 1 psi of factory set pressure
