The example shown is a valve control for the operation of two services from two separate pump supplies. The most typical application is for the control of two drive motors on a piece of mobile machinery. Each side of the valve circuit has a normally open safety unloader adding an extra level of protection to prevent unwanted operation / pressurisation of the hydraulic circuit. Valve sizing and optimised manifold design ensures that hydraulic efficiency is uncompromised with lower heat generation being seen in comparison to other market solutions. Cetop directional valves are specified separately, it is recommended that open centre (all ports open in neutral) or figure 4 (P blocked, A & B to T in neutral) spools are used.
