Product catalog summary

Overview of Flow Control Valves

Flow control valves are vital for regulating oil flow in hydraulic circuits. They come in various types such as cartridge and complete body valves, tailored to different applications.

Main Categories of Flow Control Valves

Throttle Valves: Regulate flow by constricting oil passage; excess oil is discharged via a pressure relief valve on the supply line. This causes energy loss and heating, often requiring heat exchangers. Suitable for low duty cycles and minimal excess flow. Allows reverse flow.
Pressure Compensated Valves: Maintain constant flow regardless of pressure changes, ensuring stable hydraulic performance.
Flow Dividers and Combiners: Enable simultaneous and independent flow distribution to multiple actuators, unaffected by pressure variations.

Technical Specifications and Parameters

Viscosity: Recommended oil viscosity ranges ensure optimal valve function.
Operating Temperature: Valves operate reliably within specified temperature limits.
Filtration: Absolute filtration is mandatory to prevent damage and extend valve life.
Maximum Flow Rate: Defined per model, typically in liters per minute.
Maximum Pressure: Pressure ratings up to 250-350 bar depending on valve type.
Tightening Torque: Specified torque values ensure proper assembly and adjustment.

Valve Adjustment and Control Options

External Screw with Hexagon Socket: Allows precise flow regulation using a hex key.
Handwheel and Nut: Facilitates manual adjustment for ease of use.
Knob with Locking Screw: Secures flow settings to prevent accidental changes.

Product Categories and Models

Flow Regulators (Models VEI, A, B, M, etc.): Adjustable flow rates from 0-10 l/min up to 150-250 l/min; pressure ratings up to 250 bar; various adjustment mechanisms; some models unidirectional.
Throttles and Unidirectional Throttles (Models ST, SP): Steel body valves with bidirectional or unidirectional flow control; detailed dimensional data provided.
Flow Dividers (DFR Series): Aluminum body valves dividing flow precisely; flow ranges from 2-4 l/min to 92-150 l/min; pressure ratings up to 250 bar.
Pressure Limiting Valves: Adjustable pressure settings with color-coded springs indicating ranges from 5 to 350 bar.

Operating Conditions and Recommendations

Ensure correct fluid viscosity and absolute filtration for valve longevity.
Observe flow direction restrictions to avoid damage, especially in unidirectional models.
Use recommended tightening torque during installation.
Select appropriate adjustment codes and calibrations based on application needs.

Body Materials and Construction

Aluminum Bodies: Lightweight, suitable for general applications.
Steel Bodies: Higher strength for elevated pressure environments.
Cast Iron Bodies: Robust construction for demanding applications.

Dimensional Data

Detailed dimensions (lengths, diameters, heights) are provided for installation and integration purposes across models.

Technical Component Description

Knob (Manopola): Used for manual flow or pressure adjustment.
External Screw (Vite Esterna): Hexagon recessed design for precise adjustment with a hex key.
Cap (Cappellotto): Protective element covering screws or components.
Cast Iron Body (Corpo in Ghisa): Provides durability and strength to the valve assembly.
