While specifying the directional control valves, the direction control valve exporters should evaluate the following parameters:
- Flow Control: The directional flow can also include flow control. It might usually be gifted throughout port sizing as well as putting the chops in outlet flow. In case flow control becomes part of valves, the technique for flow control need to be ascertained with the tolerance as well as accuracy of flow design as well as off-design circumstances should be assessed.
- Pressure Drop: It is pressure drop by manufacturer at the rated flow using the valves. There can be an acceptance on pressure drops that should be evaluated.
- Pressure Ratings: Ensure that valve is appropriate for pressure of your system
- Process of Spool Position Controlling: The directional valves may be controlled through a linkage, a solenoid, pneumatic source, torque motor, or hydraulic pressure sources. The source requires to be assessed under all predictable conditions to make sure if may open or close valve as needed. Extra specifications can likely to be needed for control elements.
- Temperature Ratings: Valve needs to be rated of fluid temperatures as well as appropriate environmental temperatures.
- Valve Material: It should be adequate to burst testing as well as pass proof, not become vulnerable to corrosion as well as other ecological considerations as well as not source any problems during extreme temperature.
