Serie F-002A, F-003A, F-003B 

Control Valves for High Gas Flow

These are patented indirect acting control valves suitable for high flow rates, up to 500 m3n/h N2-equivalent. They use a the 'Vary-P' mechanism (see series F-033) as pilot valve. Hence they are also pressure compensated, so both the inlet pressure and the outlet pressure may change within the specified ∆P limits, without impact on the control function.
