Tightening Torque for Mounting Bolt Change Direction of DIN Connector/Cable Entry . Unscrew retaining screw, pull off outer cover, rotate connector block through 180°. Replace cover and tighten screw. How to Calculate the Flow Rate For obtaining the flow rate, refer to front matter 42 to 45. Used as a 3 Port Valve Caution Plugging one of the cylinder ports (A or B) enables use as a normally closed (N.C.) or normally open (N.O.) 3 port valve. It is convenient when 3 port valve is needed on a manifold, etc., but it can’t be used in special applications such as using as a non-leakage valve. Use it with the exhaust port leaving open. How to Exchange Solenoid Valves, Pilot Valve Assemblies How to exchange solenoid valves . Loosen set screw and take solenoid valve out vertically, otherwise it may cause damage to the solenoid valve. Never remove valve at an angle. . When mounting solenoid valve on to the base, plug pin assembly (base-side) into receptacle assembly (body-side) vertically. Series VFR2000 Series VFR3000/4000/5000 Series VFR6000 How to exchange pilot valve assemblies . Possible to exchange pilot valve assemblies like the following figures.
