Double valve combination HF Bloc Dungs

Double valve combination HF Bloc
  • These double gas valves HF Bloc is an integration of two pneumatically controlled butterfly valves HFSV to a compact fitting.
  • Double valve combinations are used where previously two single valves have been used. Diverse control oriented tasks can be performed in combination with Dungs gas pressure control devices and additional components.
  • Normally closed, fast closing under 1 second and fast opening: <1 s (DN 50 - DN 150) and < 2.5 s (DN 200 - DN 300).
  • Max. operation overpressure of up to 500 mbar (5 bar for HP models), ambient temperature is 0÷60 0C.
  • Degree of protection IP 54 or IP 42.
  • Nominal pressure for pneumatic drive: 6÷8 bar.
  • High flow rates with minor pressure losses.
  • Pneumatic actuator with an integrated solenoid valve to control compressed air supply.
  • Suitable for gases of families 1, 2, 3 according to DVGW G 260 and other neutral gases. DSLC-SG for biogases according to DVGW G 262 and special gas applications (depending on evaluation of gas analysis specific for the system).
  • Note: HF-Bloc DSLC-SGH/SGV series is no longer part of the Dungs main product line.

Driving function

Drive opening HF Bloc Drive closing HF Bloc
For switching the solenoid valve, the control connection of the valve is presurized, the interior chamber of the cylinder is filled and the pistons move apart. During the 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 under 1 second.
