Product Description
Pilot Operated Check Valve (Modular)
Pilot operated check valve (Modular) -CIM 06
These modular valves are available with the pilot operated check valve facility on either 'A' or 'B' ports. The hydraulic opening operation for free flow in reverse direction is achieved by means of internal pilot pressure available from the other working port. Interface conforming to
ISO 4401-AB-03-04-A
IS 10187
DIN 24340
To ensure proper closure of both valve poppets, both user connections should be unloaded when the control valve is in the neutral by connecting with the return line.

Reliable and Compact Modular Check ValveEngineered for performance and longevity, this pilot operated check valve features a modular port pattern and compact dimensions, making it highly adaptable for industrial hydraulic circuits. The advanced sealing technology and robust materials ensure operation at high pressures, while its corrosion-resistant finish extends lifespan even in challenging environments. Easy integration with standard ISO 4401/CETOP manifolds reduces installation effort.
Versatile Sizing and Superior Flow ControlAvailable in NG6 (CETOP 3) and NG10 (CETOP 5) sizes, this modular check valve supports flow rates up to 80 l/min (model specific) and operates at speeds up to 30 l/min depending on configuration. Standard 0.5 bar cracking pressure assures quick, reliable operation, and optional settings can be provided upon request to meet specialized needs.
Rugged Construction With Enhanced DurabilityThe valves body is crafted from high-grade cast iron or steel, chosen for their strength and durability. Surface treatments such as black oxide coating and zinc plating provide excellent protection against corrosion, making the product ideal for long-term use in industrial settings. Nitrile or Viton seals deliver effective leak resistance and thermal stability.
FAQs of Pilot Operated Check Valve (Modular):
Q: How does a pilot operated check valve work in hydraulic circuits?
A: A pilot operated check valve permits flow in one direction and blocks reverse flow until a pilot pressure opens the valve. This design ensures controlled, secure circuit operation and is particularly useful for actuator positioning and hydraulic clamping systems.
Q: What are the benefits of using a modular pilot operated check valve?
A: Using a modular design allows for easy installation, maintenance, and replacement. It integrates seamlessly with standard ISO 4401/CETOP manifolds, enabling flexibility and rapid setup in various hydraulic applications.
Q: When should I consider using different cracking pressures for my application?
A: Different cracking pressures enable fine-tuning of system response and backpressure control. While the standard is 0.5 bar, selecting an alternative setting is advisable if your application requires specific opening characteristics or if you manage highly sensitive or varying loads.
Q: Where can this valve be installed for best performance?
A: This valve is optimized for installation in industrial hydraulic circuits such as those found in machine tools, presses, and clamping systems. Its modular port pattern and compliance with ISO 4401/CETOP 03/05 standards make it suitable for any hydraulic manifold system requiring reliable check function.
Q: What is the process of installing the pilot operated check valve?
A: Installation involves placing the valve onto a compatible modular manifold using mounting bolts. Proper alignment and secure fastening, along with installation of provided nitrile or Viton seals, ensures a leak-free connection. The supplied installation manual guides through each step for safe commissioning.
Q: How does the valve maintain low leakage at high pressures?
A: High-grade materials, precision machining, and advanced sealing elements (nitrile/Viton) enable the valve to restrict internal leakage to 0.3 ml/min at its rated operating pressure up to 315 bar, ensuring system efficiency and safety.
