1 2 1 2 1 2 1 2 1 2 1 2 VNA VNA Skip valve function Combination of 2 or more valves of Series VNA provides a skip valve function. Connect the skip valve to the A port side of a stop valve. When speed controller is mounted Connect a speed controller (Series AS etc.) to A port of VNA�ｭ11 (in order to protect the speed control valve from surges when cylinder operation is suspended, thus improving stopping accuracy).

They are suited to operate large bore cylinders as well as to simultaneously operate multiple cylinders and suspend their operation. Thus they can be used in the same way as the conventional air-hydro units. Refer to Best Pneumatics No. 7 for the details of valves. The balance poppet permits normal and reverse flow. Operation from 0 MPa is possible. Wide variations N.C., N.O., C.O., types are available. Threaded type from 6A to 50A is standardized.
