Abstract
A manifold valve has a larger valve port, through which a spool slides, than conventional relative to the size of the valve body. When the size of the valve port is fixed, the size of the entire valve can be made smaller. The walls on both sides of the valve port have no holes to pass bolts to fasten the valve body to a manifold base etc. The side walls are at least made thinner than the walls having bolt holes, within the limit in which the strength to withstand the pressure of the fluid passing therethrough remains unimpaired. The valve is fastened to the valve mounting surface of the manifold base etc. by clamping at its front and rear ends.
