Function, section for Z2FS Series Throttle valve
Valve Type Z2FS: Throttle Check Valve
- Design: Sandwich plate
- Purpose: Flow limitation for one or two actuator ports
Functionality:
- Throttle Check Valves: Two symmetrically arranged valves limit flows in one direction and allow free return flow in the opposite direction.
- Throttling Process: In supply throttling, hydraulic fluid flows through channel Aâ‘ via throttling point (1) to actuator Aâ‘¡.
- Adjustment Mechanism: The throttle spool (2.1) can be axially adjusted via the spindle (3) to adjust the throttling point (1).
- Flow Control: Hydraulic fluid in channel Aâ‘ is directed via bore (4) to the piston side (5), with active pressure and spring force retaining the throttle spool (2.1) in position.
- Return Flow: Hydraulic fluid return flow from actuator Bâ‘¡ displaces the throttle spool (2.2), enabling unobstructed flow as a check valve.
- Version Dependent Throttling: Depending on the version (“S” or “S2”), throttling may occur in supply or discharge.
Application:
- Actuator Velocity Adjustment: The throttle check valve is installed between the directional valve and the subplate for flow limitation.
