Honeywell’s Solenoid Valves

Quality solenoid valves form Honeywell for natural gas and lpg gas shut offThe HF500 can be used with Honeywell’s solenoid valves – VG400SA and VG4000S (normally open) and VG400AA (normally closed) to provide an automatic gas shut-off system.

The valves are constructed in such a way that manual intervention is needed to reopen the valve after the alarm threshold has been exceeded.

Honeywell’s solenoid valves provide a fast closing time of less than one second, official approval to EN161 and an IP54/65 rating preventing an unsafe state resulting from accidental water damage.

Key features of Honeywell’s solenoid valves:

  • Closing time <1 sec
  • Maximum inlet pressure of 500 mbar
  • Rated voltage of 220..240 Vac
  • Electrical connection with standard DIN plug
  • CE approved: EN161; GAD and LVD

The HF500 alarms reduce costs by negating the need for additional equipment when used with a solenoid valve, unlike some comparable solutions. Installation is also simplified through a design that features installer-friendly wiring and cable entries from the back, or via mini trunking from the sides or bottom. There is also no need to rewire the device when replacing the alarm or sensors.
