VBD/VP Bidirectional Check Valve offered by Hidroteknik is a type of check valve with a bidirectional working principle . This valve prevents the flow from reversing in systems where two-way flow must be controlled. VBD/VP valves are widely used in industrial and mobile hydraulic systems with high performance and low leakage.

  • Nominal Flow Capacity:
    • VBD 38: 20 L/min (5.2 US gpm)
    • VBD 12: 40 L/min (10.5 US gpm)
    • VBD 34: 60 L/min (15.8 US gpm)
    • VBD/VP 38: 90 L/min (23.8 US gpm)
  • Maximum Working Pressure:
    • Steel Body: 350 bar (5100 psi)
  • Connection Types: G3/8 port connection option
  • Leakage: 0.5 cm³/min (0.030 in³/min) leakage rate @ 210 bar (75% pressure setting)
  • Fluid Type: Mineral based hydraulic oils (10-200 cSt viscosity)
  • Pollution Level: 18/16/13 pollution level according to ISO 4406 standard
  • Operating Temperature: -20°C to 80°C (with NBR seals)
  • Body Material: Durable steel body

Design and Adjustability

  • Double Way Check Valve:
    This valve allows fluid to flow in both directions, but prevents reverse flow in either direction, thanks to its bi-directional design. This design is perfect for circuits that need to control the flow directions in the system.

  • Connection Options:
    The G3/8 threaded connection allows the valve to be integrated into a variety of systems. This offers flexibility of use in both industrial and mobile hydraulic systems.

  • Durable Body Design:
    The steel body allows the valve to withstand high pressures. This feature ensures reliability in systems with excessive loads.

Advantages:

  1. Two-Way Operation:

    • Provides two-way flow control .
    • Controls the direction of flow and prevents reverse flow.

  2. Low Leakage Level:

    • It minimizes hydraulic losses in the system with a leakage rate of 0.5 cm³/min.

  3. High Compressive Strength:

    • It offers reliable performance in harsh operating conditions with a working pressure of up to 350 bar .

  4. Easy Installation and Connection:

    • G3/8 connection allows you to quickly install and commission the system.

  5. Two-Way Flow Control:

    • With its bidirectional design, it provides two-way flow control and completely prevents reverse flow.

  6. High Durability:

    • Steel body provides superior durability in harsh environmental conditions.

Areas of Use:

The VBD/VP Double Way Check Valve is commonly used in the following industrial and mobile hydraulic applications:

  • Press Machines and Industrial Compression Systems: Controls the flow rate in the systems and prevents backflow.
  • Mobile Hydraulics: Controls system flow and prevents reverse flow in tractors, excavators, cranes and mobile platforms.
  • Hydraulic Power Units: Used to control the flow rate at the pump outlet and prevent reverse flow.
  • Industrial Automation: Used in automation systems and circuits where flow rate is controlled.
