Elektrogas Butterfly Valve

Elektrogas Butterfly Valve

Description VF and VFH butterfly valves are designed for regulati on and control of gas flow and air flow in combustion processes. Valves can be operated manually using a lever (to s etup the high-fire rate of the burner) or automatically using a servomotor (modulating or sta ged control) or a solenoid actuator (two- stage control). Features Valves are made of aluminium casting (VF type) or cas t-iron (VFH type), with wide range of connections from DN40 up to DN150. Installation between EN 1092 flanges. Possibility to have one-size or two-size reductions of the nominal diameter for VF type. Suitable for use with air and non-aggressive gases a ccording to EN 437 (VF type); heated air and flue gas (VFH type). Low leakage when valve is in closed position (VFH ty pe provided with butterfly disc stop). The VFH type is provided with a double-eccentricity disc and a spring to reduce the backlash. This results in an high precision adjustment and av oids valve floating. Operated by manual lever, servomotor or by solenoid actuator. All components are designed to withstand any mechani cal, chemical, thermal condition occurring during typical service. Effective impregna tion and surface treatments have been used to improve mechanical sturdiness, sealing and resis tance to corrosion of the components.
