Сдвоенные дроссельные обратные клапаны прямого действия Z2FS 6...XC

Description Size 6 Component series 4X Maximum operating pressure 315 bar Maximum flow 80 l/min Area of application according to directive 94/9/EG I M2, II 2G, II 2D Type of protection of the valve: c (EN 13463-5:2004-03) Features Sandwich plate valve • Porting pattern according to ISO 4401-03-02-0-05 with locking pin and locating hole • Setscrew with lock nut and protective cap • For the main or pilot flow limitation of two actuator ports • For supply or discharge throttling Product description Valves type Z2FS 6...XC are twin throttle check valves in sandwich plate design. They serve for 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 valve seat (2) and the throttle spool (3) to actuator A2. The throttle spool (3) can be axially adjusted via the setscrew (4) for adjustment of the throttling point (1). The hydraulic fluid return flow from actuator B2 displaces the valve seat (2) against the spring (5) in the direction of the throttle spool (3) and enables the unobstructed flow via the check valve from B2 to B1. The same applies for flow into the opposite direction. Depending on the type, the throttling effect may occur in supply or discharge. Main flow limitation (Version ..2Q..) For actuator velocity adjustment (main flow limitation), the twin throttle check valve is installed between the directional valve and the subplate. Pilot flow limitation (Version ..1Q..) With pilot-operated directional valves, the twin 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.
