SV/SL TYPE OF FLOW CONTROL CHECK VALVE
A directional valve is a type of hydraulic or pneumatic control component that directs or controls the flow of fluid (oil, air, or other media) by switching flow paths. It determines the path of fluid flow in a hydraulic or pneumatic circuit, controlling the direction of motion of actuators like cylinders and motors.

Flow Control Check Valve Overview

This Flow Control Check Valve series is designed to manage hydraulic fluid flow with optional features for pilot control, subplate mounting, and various pressure and port configurations. It provides customizable flow control to meet specific application requirements and reduces hydraulic impact with buffer and release mechanisms.

Features:

  1. Flow control check valve with subplate installation.
  2. Connection dimensions per DIN24340.
  3. Available with or without a drain port, as needed.
  4. Available with or without a pilot valve for enhanced control.
  5. Buffer and release pressure functionality using the pilot valve.
  6. Three selectable starting pressures to fit various applications.
