【English Version】
The DFY-B32H2 Hydraulic Control Check Valve is a fluid control device specifically engineered for hydraulic systems, designed to manage unidirectional flow while enabling reverse opening functionality in demanding industrial applications. Featuring a modular construction, this product combines compact dimensions with reliable pressure regulation capabilities in complex hydraulic circuits.
Key Features:
- Bidirectional Flow Control: Achieves forward conduction and reverse release through hydraulic actuation, enhancing system responsiveness. The stepped guide structure of the valve core, manufactured with precision grinding technology, ensures smooth operation without sticking.
- Superior Pressure Resistance: Main body constructed from heat-treated high-strength alloy steel with hard alloy reinforced sealing surfaces, capable of withstanding 32MPa working pressure and 42MPa transient pressure.
- Environmental Adaptability: Specialized sealing components maintain performance across -20℃ to 120℃ fluid temperatures. Dust-resistant guide sleeves extend maintenance intervals in particulate-laden environments.
- Installation Flexibility: Multiple interface options including SAE flanges and ISO threads comply with mainstream hydraulic pipeline standards, supporting both horizontal and vertical mounting orientations.
This product is widely implemented in scenarios such as outrigger locking systems for construction machinery, mold clamping devices in metallurgical equipment, and hydraulic circuits for marine deck machinery. Each unit undergoes rigorous quality verification including pressure testing, leakage inspection, and operational cycling before shipment.
Our technical support team provides professional consultation for model selection and system optimization. The product is backed by an 18-month warranty from date of shipment, accompanied by comprehensive installation guidelines and maintenance recommendations.
