Description
The LIGHT model safety valve with manual handwheel is an automatic safety valve designed to open in the event the internal pressure of the system exceeds a predetermined maximum pressure (Preset Nominal Pressure: Pnr) allowing the water to discharge through it. The safety valve resets automatically preventing any further fluid flow 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 fluids by an industrial rubber diaphragm. The handwheel enables the valve to open even at pressures lower than the calibration value , thus allowing the verification of its proper operation at any time.
Tech Spec
- preset nominal pressure (Pnr); 6 bar
- maximum temperature; 115 °C (water or air - Class 2 liquids)
- glycolate solutions; glycol 50%
- Body; Brass
The LIGHT model safety valve with diaphragm and handwheel activation satisfies the essential safety requirements stipulated in the EU Pressure Equipment Directive PED 2014/68/UE (Pressure Equipment Directive).
