ISO 185:2021 Grade GG25 Gray Iron Hydraulic Valve Block Engineered for precision fluid control in extreme industrial environments, this valve block ensures reliable performance in high-pressure hydraulic systems.
Technical Specifications & Design Constructed from ISO 185:2021 Grade GG25 gray iron, the valve block offers exceptional resistance to mechanical stress and corrosion, with a tensile strength of 250 MPa. The 3/2-way directional control valve design enables bidirectional fluid flow, while the built-in bypass mechanism mitigates pressure surges during rapid actuation. NPT 3/8″ inlet and 1/4″ outlet ports (ISO 7-1 compliant) ensure compatibility with standard hydraulic hoses and fittings.
Performance Advantages
Pressure Stability: Maintains consistent flow control at 250 bar continuous pressure, with a 300 bar burst pressure rating for safety redundancy (SAE J1401 compliant).
Temperature Resilience: Operates reliably in extreme conditions (-20°C to +80°C), making it suitable for arctic mining and high-temperature industrial applications.
Leakage Prevention: Precision-machined port threads (Ra ≤1.6μm surface finish) and O-ring seals (ISO 3601 compliant) ensure zero leakage during high-vibration operations.
Applications
Construction Machinery: Ideal for excavators, loaders, and bulldozers, controlling hydraulic cylinders for bucket articulation and boom elevation.
Agricultural Equipment: Used in tractors and combines to manage hydraulic drives for implements like plows and harvesters.
Industrial Hydraulics: Supports material handling systems and presses, providing reliable flow control in factory automation and metalworking processes.
