Дроссельный обратный клапан Z2FS 10

Description Size 10 Component series 3X Maximum operating pressure 315 bar Maximum flow 160 l/min Features Sandwich plate valve Porting pattern according to ISO 4401-05-04-0-05 For the main or pilot flow limitation of 2 actuator ports. 3 adjustment types: • Lockable rotary knob with scale• Spindle with internal hexagon and scale• Rotary knob with scale Meter-in or meter-out throttling Corrosion-protected design Product description The valve type Z2FS 10 is a throttle check valve in sandwich plate design. It is used for the main or pilot flow limitation of one or two actuator ports. Two throttle check valves aligned symmetrically to each other limit flows in one direction and allow free return flow in the opposite direction. In case of supply throttling, the hydraulic fluid is directed through channel A1 via throttling point (1) formed by the control edge (2) and the throttle spool (3.1) to actuator A2. The throttle spool (3.1) can be axially adjusted via the spindle (4) for adjustment of the throttling point (1). Simultaneously, the hydraulic fluid in channel A1 is directed via the bore (5) to the piston side (6). The active pressure and the spring force retain the throttle spool (3.1) in throttle position. The hydraulic fluid return flow from actuator B2 displaces the throttle spool (3.2) against the spring (7) and enables the unobstructed flow as check valve. Depending on the installation position, the throttling effect may occur in supply or discharge. Main flow limitation For actuator velocity adjustment (main flow limitation), the throttle check valve is installed between the directional valve and the subplate. Pilot flow limitation With pilot-operated directional valves, the throttle check valve can be applied for switching time adjustment (pilot flow limitation). In this case, it is installed between the pilot control valve and the main valve.
