GS40 DSB

The butterfly valves, model G.S.40, are worked by a single-action hydropneumatic actuator with return spring, hand-wheel for turning it off and bushing for regulation of the piston stroke.?
?
The use of large diameter cylindres ensures that the valves can function even when drive pressures are relatively low.?
?
At customers’ request the valves can be supplied set either “normally open” or “normally closed”.
