In the case of 3 position double check valve (VFS56�ｭ0), check the leakage from piping and fittings in between valve and cylinder by means of synthetic detergent solutions, and ensure that there is no such leakage found there. Also check the leakage from cylinder seal and piston seal. If there is any leakage, sometimes the cylinder, when valve is de-energized, can move without stopping at intermediate position. . Be aware that if the exhaust side is restricted excessively, the intermediate stopping accuracy will decrease and will lead to improper intermediate stops. . The combination of VFS51 0, VFS52 0 and a double check spacer can be used as prevention of falling at the stroke end but cannot hold the intermediate position of the cylinder. Series CS1/CS2 Pressure 0.5 MPa Load factor 50% Stroke 300 mm . It is when the cylinder is extending that is meter-out controlled by speed controller which is directly connected with cylinder, and its needle valve with being fully open. . The average velocity of the cylinder is what the stroke is divided by the total stroke time. . Load factor: ((Load mass x 9.8)/Theoretical force) x 100% Use as a guide for selection. Please confirm the actual conditions with SMC Sizing Program.
