In-Line Check Valves (NRV) - C06 to C30

The C06 to C30 In-Line Check Valve (NRV) is a reliable hydraulic valve designed to prevent reverse flow in hydraulic and fluid handling systems. It allows free flow from Port A to Port B while ensuring leak-free closure in the opposite direction, helping protect system components and maintain safe operation.

These check valves are engineered for dependable performance, easy installation, and simple maintenance. With seat-type construction and multiple cracking pressure options, they are suitable for a wide range of industrial hydraulic applications.

Applications

  • Fluid handling systems
  • Hydraulic power units
  • Oil and gas industry equipment
  • Industrial hydraulic systems
  • Lubrication and pressure control circuits
  • Machine tools and process equipment

Technical Features

Working Pressure 315 bar for Ports A and B.
Sizes Available From 1/4" BSP to 1-1/2" BSP.
Mounting Options Threaded port or subplate mounting options available.
Cracking Pressure Available in 0, 0.5, 1.5, 3 and 5 bar options.
Construction Seat type valve construction for reliable sealing performance.
Flow Direction Free flow from Port A to Port B with leak-free closure in reverse direction.

Pilot Check Valves

The Pilot Operated Double Line Check Valve provides advanced control and safety in hydraulic systems. It is designed to maintain pressure while allowing pilot operation, making it an excellent choice for complex hydraulic circuits where controlled flow and secure load holding are required.

These check valves allow free flow in only one direction, while the opposite flow direction is managed by a crossed pilot signal. This helps improve hydraulic circuit safety, stability, and operational reliability in demanding applications.

Applications

  • Hydraulic systems requiring pilot control
  • Industrial and mobile hydraulic equipment
  • Aerospace and defense hydraulics
  • Hydraulic lifting and holding circuits
  • Heavy-duty machinery and automation systems

Technical Features

Nominal Flow Up to 80 L/min.
Max. Pressure 350 bar / 5100 psi
Available In G1/4, G3/8 and G1/2 sizes.
Valve Type Pilot operated double line check valve.
Flow Direction Allows free flow in one direction only.
Pilot Operation Reverse flow is controlled through a crossed pilot signal.
