Modular check valve Z2FS

At its core, the Z2FS check valve operates as a double throttle check valve, boasting a stacked design that sets it apart from conventional counterparts. This design incorporates two throttle check valves symmetrically arranged to govern fluid flow meticulously. The primary objective of this valve is to limit the main flow or control the flow within one or two working oil ports, providing engineers with a versatile tool for managing hydraulic systems with precision.

In scenarios where meter-in control is imperative, the oil fluid follows a specific path from port A1 to A2 through the intricately designed throttle port(1). This port comprises the valve seat (2) and throttle spool (3), components that play a pivotal role in regulating the flow. The adjustability of the throttle spool (3) along its axis, facilitated by the adjusting screw (4), empowers operators to fine-tune throttle port(1) to achieve the desired flow characteristics. Upon the fluid’s return from the working oil port A2, the valve seat (2) opens against the force exerted by the spring (5). This ingenious mechanism transforms the valve into a check valve, allowing for unrestricted free-flow in the opposite direction. The flexibility to configure the valve for meter-in or meter-out control, depending on its installation position, further amplifies its utility in diverse hydraulic applications.
