Product Description
HYDRAULIC FEATURES

The "light" model security valve with manual hand wheel is an automatic safety valve designed to open in the event the internal pressure of the system reaches a predetermined maximum pressure (Preset Nominal Pressure: Pnr) allowing the water to be released through it. The security valve resets automatically when the internal pressure of the system returns below the predetermined maximum pressure. All the moving parts of this safety valve, including the regulating spring, are isolated from heat-transfer fluids by an industrial rubber diaphragm. The "light" model security valve with manual hand wheel satisfies the essential safety requirements stipulated in the EU Pressure Equipment Directive (PED) 97/23/EC.
