SD25 – Directional Control Valve FAQ:
1. What is the SD25 – Directional Control Valve ?
SD25 is a heavy-duty sectional directional control valve for mobile machinery. It controls hydraulic actuators’ direction, speed and power. Modular design supports various control options, built-in relief and load check valves, suitable for agricultural and construction equipment.
2. What makes the SD25 – Directional Control Valve ?
Modular sectional design for flexible configuration. High pressure resistance with built-in relief and load check valves. Multiple control choices and low internal leakage, delivering stable performance for mobile machinery under tough working conditions.
3. What is the working pressure range of SD25 – Directional Control Valve ?
Max working pressure reaches 315 bar for parallel circuit, 210 bar for series circuit. Max back pressure of return port is 25 bar.
4. Can SD25 – Directional Control Valve replace other brands?
The SD25 directional control valve is designed as a drop-in replacement for numerous mainstream brand directional control valves with the same specifications. Matching installation size, oil port layout, pressure and flow parameters enable direct replacement in most cases. To avoid mismatching, kindly send us the original valve model for precise verification before purchase.
5. What is the typical speed range of SD25 – Directional Control Valve ?
The SD25 directional control valve itself has no fixed rated speed range. The movement speed of hydraulic actuators (hydraulic cylinders, hydraulic motors) is determined by the actual flow supply of the hydraulic system. Within its rated flow capacity, this valve can satisfy conventional speed regulation demands for mobile machinery such as agricultural equipment and construction machinery. If you have specific requirements for actuator operating speed, please offer your system flow parameters for further compatibility confirmation.
6. Do you provide OEM or customized services?
Yes, we support OEM and customized services for the SD25 directional control valve. We can make adjustments on logo, marking, port configuration, control modes and other aspects according to customer requirements. Please share your detailed customization demands so we can confirm the feasibility and relevant lead time.
7. How can I get a quotation quickly
