MCV Series Modular Check Valves (Size 02 & 03)

Product Overview: The MCV Series modular check valves are indispensable components in modern industrial hydraulics and mobile machinery, such as excavator control systems. Featuring a standardized Modular design, this series allows for direct stacking beneath directional valves, eliminating the need for extra piping and significantly reducing the installation footprint of hydraulic control units. Its primary function is to permit flow in one direction while reliably blocking reverse flow, commonly used for pressure maintenance in actuators or protecting pumps from back-pressure spikes.

Featured models on this page include the compact MCV-02W-1-10 and the mainstream MCV-03-P-05.

Key Technical Advantages:

• Space-Saving Design: Compliant with ISO 4401 mounting standards, the stacking configuration eliminates complex piping and reduces potential leakage points.

• Precise Cracking Pressures: Available in multiple cracking pressure options (e.g., 0.4 Bar or 3.5 Bar), ensuring sensitive actuation under varied load conditions.

• High-Pressure Durability: Engineered for heavy-duty applications, withstanding system pressures up to 25 MPa (250 Bar) to ensure control circuit safety.

• Minimal Internal Leakage: Precision-ground spool and seat assemblies guarantee a perfect seal in the closed position, providing superior pressure holding.
