This is a brass safety relief valve (model S10) designed to protect pressurized systems from overpressure. With a 1/2" (13 mm) connection size and a set pressure of 3.5 kg/cm², it automatically opens to release excess pressure when the system pressure exceeds the set value, then closes again to maintain normal operating conditions. The valve is constructed from brass, making it suitable for use with water, air, and other non-corrosive fluids in plumbing, heating, and industrial applications.
