Valve type:580 is at the same time blow-off and relief valve. As a safety relief valve it is used to control the pressure of pressure vessels, gas pipelines and gas installations, it maintains the set pressure in front of itself. It also works as an input pressure regulator (ie maintains the set inlet pressure, regardless of its variations, while the excess of pressure blow-off at the installation behind). A high-precision of pressure adjusting was achieved by the spring-loaded and membrane design solution.

Temperature operating range: -20° ÷ +60°C.
