HF Bloc-...: Double valve combination, Pneumatic actuator, One-stage butterfly valve |
HF Bloc
Double valve combination
Nominal diameter
DN 50 - DN 150
HF Bloc-...-VPS
HF Bloc-...-VPM
Technology
DUNGS double valve combination HFBloc-... is an integration of two pneumatically controlled butterfly valves to a compact fitting:
- automatic butterfly valves acc. to DIN EN 161, class A, group 2.
- max. operation overpressure of up to 5 bar (500 kPa)
- normally closed
- fast opening, fast closing
- high flow rates with minor pressure losses
- pneumatic actuator with an integrated solenoid valve to control compressed air supply
- small dimensions, low weight
- assembled valve check system
Application
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.
Suitable for gases of gas families 1, 2, 3 acc. to DVGW G 260 and other neutral gases.
Suitable for applications with low switching frequency.
Approvals
HF Bloc-... with inspection certificate
HF Bloc-... Two one-level butterfly valves, normally closed, fast opening, fast closing. Integration of two automatic butterfly valves with a valve check system at the installation length according to DIN EN 558-1 for biogases, according to G 262, gases of gas families 1, 2, 3 and other neutral gases.
