  • Max. operating pressure up to 3 or 5 bar (300 or 500 kPa).
  • Nominal pressure of control air: 6-8 bar (600-800 kPa).
  • Normally closed, fast opening, fast closing.
  • High flow rates with minor pressure losses.
  • Degree of protection IP 65. Medium teperature -10 ÷ 60 0C.
  • Design without non-ferrous metals. Suitable for gases according to G 262, gases of gas families 1, 2, 3 according to G 260 and other neutral gases. The HFSV SG are designed for special gas applications, depending on evaluation of gas analysis specific for the system.

Driving function HFSV

Drive opening HFSV Drive closing HFSV
For switching the solenoid valve, the control connection of the valve is pressurized, the interior chamber of the cylinder is filled and the pistons move apart. During this process the motor shaft rotates counterclockwise, the valve is opened and the spring units are tensioned. Switching of the solenoid valve during a pressure loss or power failure deaerates the interior chamber, the spring units under tension are released and press the pistons together < 1 second.
