Mounting Connection Forms
Screw type (pipe type): For simple hydraulic systems where the oil port is connected to the pipe by a screwed pipe fitting.
Screw type: Suitable for complex hydraulic systems where the valve can be removed without dismantling other components connected to it.
Stacked type: compact structure, low resistance loss, suitable for applications requiring compact design.
Flange type: suitable for large flow system with a diameter of 32 or more, high strength and reliable connection.
The basic requirements of hydraulic control valve
Sensitive action, reliable work, shock and vibration as small as possible.
When the valve port is fully open, the pressure loss when the oil through the valve port should be small.
Good sealing performance when the valve port is closed, no external leakage is allowed.
The controlled parameters (pressure or flow) are stable, and the amount of change is small when subjected to external interference.
The structure should be simple and compact, easy to install, debug and maintain, good generality.
Technical parameters

Application Scenario
The manual directional valve is suitable for a variety of industrial hydraulic systems, especially in the need to accurately control the direction of liquid flow in the application of outstanding performance. Its reliable performance and a variety of installation methods make it the preferred component of many hydraulic equipment.

Selection basis
Piping Parameters
Determine the diameter (DN) size according to the internal diameter of the pipeline or flow requirements on site.
Interface mode, generally DN50 to choose flange interface, ≤ DN50 can be freely selected according to user needs.
Fluid parameters
Material: corrosive fluid should choose corrosion-resistant solenoid valve and all stainless steel; edible ultra-clean fluid should choose food-grade stainless steel solenoid valve.
Temperature group: high-temperature fluid to choose the use of high-temperature resistant electrical materials and sealing materials manufactured by the solenoid valve, and to choose the type of piston structure.
Pressure parameters
Nominal pressure: according to the nominal pressure of the pipeline to determine.
Working pressure: If the working pressure is low, you must choose direct-acting or step-by-step direct-acting principle; working pressure difference of 0.04Mpa or more when the direct-acting, step-by-step direct-acting, pilot-operated can be selected.
Electrical selection
Voltage specifications should try to prioritize the selection of AC220V, DC24 is more convenient.
Continuous working time
When the solenoid valve needs to be opened for a long time, and the duration of time is more than the closing time should be selected normally open type.
If the opening time is short or the opening and closing time is not much, then select the normally closed type.
Environmental requirements
Select the auxiliary function according to the environmental requirements: explosion-proof, check, manual, waterproof fog, water shower, submersible.
