Product Overview
The MPCV-03B is a stackable pilot-operated check valve designed for hydraulic systems. Manufactured from cast iron, it operates with oil medium within a temperature range of -20℃ to 80℃ and nominal pressure up to 21MPa. Featuring sandwich mounting design, it can be directly installed between solenoid valves and manifolds, offering compact structure and easy assembly while effectively reducing system leakage, vibration and noise. The series includes multiple specifications to accommodate different port sizes (02/03/04/06mm).358
Key Features
This valve provides unidirectional flow control with hydraulic release capability, suitable for cylinder supporting, pressure maintenance and locking applications. Its pipeline-free design simplifies circuit configuration and maintenance, allowing rapid system modification. The wear-resistant construction with optimized internal structure ensures stable performance under high pressure. Also known as "hydraulic lock", it prevents unintended cylinder movement caused by gravity or external force, enhancing operational safety.182122
Technical Specifications
With 10mm nominal bore (03 size), the valve operates at 25MPa working pressure and 70L/min maximum flow rate. Compatible with ISO VG32/46/68 hydraulic oil (10-400mm²/s viscosity), it offers three control port configurations: A-port, B-port or W-type (A+B composite). Two cracking pressure options available: 0.35MPa (05 series) and 3.5MPa (50 series) for different load requirements. Phosphate coating treatment improves corrosion resistance.2428
Applications
Widely used in construction machinery, mining supports and metallurgical equipment requiring hydraulic control. Typical applications include preventing piston rod drifting in vertical cylinders, maintaining circuit pressure, cylinder locking and high-flow discharge scenarios. Compatible with standard hydraulic manifold patterns, it s commonly integrated into excavator valves, road roller vibrators and crane hydraulic systems.171926
