Solenoid operated butterfly valves for air

Solenoid Driven Butterfly Valves VF

Air butterfly valves with solenoid actuator in DN 40 up to DN 150 (VFH DN 40 - DN 80) for ON/OFF controlled burner systems. The stopper of the VFH-series provides lowest leakage rates.VFH-valves are applicable up to 450°C air temperature. All valves are equipped with an adjustment for the minimum and maximum air flow. Alternatively are slow opening or fast opening actuators available.

 

FEATURES

  • For HIGH / LOW or ON / OFF control of the air supply for industrial burners
  • Solenoid operated valve with spring-loaded butterfly disk
  • Flow adjustment and position indicator
  • VF-series for cold air (up to 200°C) and VFH for preheated air (up to 450°C)
  • High flow rate but low leakage rate
  • VFH-series with molding for low leakage rates
  • VF-series available as continuous operating control valve with gear motor RA 310 or RA 500
  • Suitable for pulse mode and permanent operation
