    • A hydraulic directional control valve assembly (200) adapted for use subsea without a pilot valve stage and its methods of use are disclosed. The hydraulic directional control valve assembly (200) comprises a pulse operated hydraulic directional control valve (04), a separate fail safe mechanism (10) to bring the valve (04) to a predetermined position and a single electric actuator (19) operatively connected to the hydraulic directional control valve (04), the hydraulic directional control valve (04) having a first and second position relative to electric actuator (19), the electric actuator (19) further adapted to selectively change the position of the hydraulic directional control valve (04) with respect to passageways (71, 72, 74) with which hydraulic directional control valve (04) may be in communication, to selectively change the direction of the fluid flow through hydraulic directional control valve (04).
    • 公开了一种适用于没有先导阀级的海底使用的液压方向控制阀组件(200)及其使用方法。 液压方向控制阀组件(200)包括脉冲操作的液压方向控制阀(04),将阀(04)带到预定位置的单独的故障安全机构(10)和可操作地连接的单个电致动器(19) 所述液压方向控制阀(04)具有相对于所述电致动器(19)的第一和第二位置的所述液压方向控制阀(04),所述电动致动器(19)还适于选择性地改变所述液压方向控制器 阀(04)相对于与液压方向控制阀(04)可以连通的通道(71,72,74),以选择性地改变通过液压方向控制阀(04)的流体流动的方向。
