CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Hydraulic valves control the direction, pressure, and flow of hydraulic fluid within a system. They regulate actuator motion, force, speed, and system pressure by directing, throttling, or shutting off pressurized fluid.
Key parameters include nominal diameter, maximum operating pressure, flow rate, leakage rate, response time, operating temperature, IP rating, coil voltage, power consumption, body material, and weight. These values must be verified for the specific model and application.
Relevant standards include ISO 4413 for hydraulic fluid power, ISO 6403 for flow control valves, ISO 10770-1 for electrically modulated hydraulic control valves, IEC 60529 for enclosure protection, IEC 60034 for rotating electrical machines, and GB/T 9439 for cast iron. These are references for procurement and verification.
Reliability depends on proper selection, installation, and maintenance. Check that the valve's specifications match your system requirements, and verify performance through pressure-decay tests and leakage measurements. Follow the manufacturer's guidelines for operation and maintenance.
