Flow Regulator valves

Discover high-performance flow control valves for hydraulic systems that precisely regulate flow rates independently of load conditions, effectively preventing cavitation,
overheating, and motor damage. Our 3-way flow control valves direct the regulated flow to the motor while safely diverting excess flow back to the tank — optionally
equipped with an integrated pressure relief valve for maximum operational safety. Learn more...

Ideal for controlling speed and power in applications such as hydraulic sweepers, log splitters, conveyors, and municipal service vehicles. Thanks to their easy flange mounting, many models are compatible with hydraulic motor series CPM, CPRM, and CPMS, as well as with other manufacturers such as Danfoss, M+S, White, Eaton, SAM/Brewini, or Hydraulik Nord of the same design. Typical port sizes include G3/8", G1/2", and G3/4". Adjustable flow ranges of approx. 1 to 50/65 l/min (max. 60–90 l/min depending on the model) allow flexible system design. Robust housings made from zinc-plated or phosphated steel withstand operating pressures from 250 to 350 bar – perfectly suited for durable, efficient hydraulic solutions from the Hydromot Shop.

 

Flow Control Valves – Frequently Asked Questions

What are flow control valves and what is their main function?

Flow control valves are key components in hydraulic systems, providing precise regulation of flow rate and speed control of actuators such as cylinders and hydraulic motors. They ensure a constant flow rate regardless of load and pressure fluctuations within the system. Often designed as flow regulators, they limit the volume flow supplied to hydraulic motors to maintain consistent performance.

What is the basic operating principle of these valves?

Flow control valves operate according to the throttling principle, in which the cross-sectional area for hydraulic oil flow is restricted. A compensating mechanism automatically adjusts the orifice size in proportion to pressure changes, ensuring a stable and constant flow rate.

What are the main types of flow control valves?

There are two primary types of flow control valves – 2-way and 3-way flow control valves:

  • 2-way valves: Regulate the flow in one direction only.
  • 3-way valves: Divert excess flow through a third port. A portion of the flow is directed to the motor while the remainder is returned to the tank.
  • Proportional flow control valves: Electromagnetically controlled for particularly fine and stepless flow regulation.

Which materials are typically used for housings and seals?

Typical valve housings are made from steel (often gas-nitrided or zinc-plated) or aluminium. For applications involving hydraulic motors, housings are frequently manufactured from zinc-plated or phosphated steel to withstand high pressures and harsh operating environments.

Seals are generally made from FKM (Viton) or NBR, offering excellent resistance to hydraulic oils and wide temperature variations.

Where are flow control valves used?

Flow control valves are essential wherever precise motion control and uniform actuator speed are required:

  • Controlling the speed of hydraulic cylinders and motors in industrial equipment, presses, and automated production lines
  • Use in agricultural machinery, construction equipment, and municipal vehicles
  • Regulating flow rates in hydraulic attachments such as sweepers, log splitters, and conveyor systems

What are the maximum operating pressures and flow rates these valves can handle?

Depending on the design and manufacturer, maximum operating pressures typically reach up to 350 bar.

The maximum flow rate ranges from 17 l/min to 120 l/min. Specific flange-mount models offer adjustable ranges between 1 l/min and 65 l/min and maximum flow capacities up to 90 l/min.

What advantages do flow control valves provide for system longevity?

Flow control valves ensure a constant flow rate regardless of load pressure, allowing accurate and repeatable actuator speed control.

  • Provide protection for expensive hydraulic motors by limiting inlet flow
  • Prevent damage caused by cavitation or overheating
  • Many models feature integrated pressure relief valves (PRV) for enhanced operational safety
  • Constructed from durable, corrosion- and wear-resistant materials
  • Precision manufacturing ensures a long service life – typically lasting for many years of continuous operation
