Never use a stopper plug in the T(R) port. xEnsure that surge pressure in excess of the maximum allowable back pressure does not reach the T port. cNote that the maximum flow rate is limited when used as a four-way valve, or by blocking ports for use as a two-way valve or one-way valve. vAlways keep the operating fluid clean. (contamination level: 12 or lower) bWhen using petroleum type operating fluid, use JIS K 2213 Class 1 or Class 2, or equivalent. nUse the SS series solenoid valve when using fire resistant hydraulic operating fluid. mUse this valve only within the allowable voltage range. ,Do not allow the AC solenoid to become charged until you install the coil into the valve. .Maintaining a switching position under high pressure for a long period can cause abnormal operation due to hydraulic lockup. Contact your agent when you need to maintain a switching position for a long period. ⁄0When using a detent type (3X), use constant energization in order to securely maintain the switching position. ⁄1Note that manual pin operating pressure changes in accordance with tank line back pressure. ⁄2Use the following table for specification when a sub plate is required.
