Argo Hytos Flow Control Valves

Argo Hytos flow control valves enable a throttling of the flow rate. This helps the control of piston rod velocity, or the shaft speed of a hydraulic motor by varying the flow cross-section. Valves with pressure drop stabilisation maintain a set flow independent on the change in external load on the appliance.

For 2-way pressure compensation, the valve inlet pressure is controlled based on the outlet pressure by throttling the flow. For 3-way pressure compensation, the regulation is achieved by draining the fluid portion back to the tank. The pressure difference of the valves determines the pressure generated by the compensator spring. For valves with pressure compensator, the flow rate through the valve can be adjusted either by the change of cross-sectional flow area or by pressure difference adjustment using the spring preload.

The full check valve range covers a number of different specializations depending on the customer’s requirements. The full line up is as follows:

• Needle restrictor valves, and valves with a reverse flow check function, are as follows:
  • ST21A-B2, ST2(C)1A-A2, VSV2 and VSO1-04/R models
• The double throttle check valve range comprises:
  • VSO1-04/M, 2VS3-06 and VSO3-10/M models
• Cartridge design flow control valves:
  • VSK series valves – utilising an in line mounting design.
• 2-way flow regulators comprising:
  • SF22A-A2/H, SF22A-B2/H, SF2C2A-K2/l, VS S1-206, VS S2-206, VSS3-062/S and VSS3-062/M models
• 3-way flow regulator range:
  • VSS1-306, SF32A-B3 and SF32A-K3/l models
• Flow divider/ combiner valves comprising:
  • SFD2F-B4/l and SFD2F-D4/l models
