directional control valve é um projeto do tipo segmento que pode ser empilhado em paralelo. É composto por três elementos – an inlet Section valve, work sections with a wide choice of spool configurations and an outlet section, all bolted together as a single unit. The number of work sections in the valve unit are determined by the number of hydraulic elements to be operated. The valves are mounted on equipment at one location to meet the requirements of controlling multiple hydraulic elements from a single point by a single operator.

Simple, compact and heavy duty designed sectional valve having parallel work sections with individual load ports for both open center, closed center and power beyond

applications. Spring center is standard. Detent options available on request. Work port relief valves and anti-cavitation check valves are available. Spool end caps, lever end or protected from dust by bellows inlet and outlet ports with threading options for UNF, BSP, NPTF. Load check valves for all spools to prevent back flow from pump. Work Port Relief valve provision to limit the pressure in each spool section.
