CONTROL METHOD: Spool type.
The G spool type is used for pump unloading and cylinder locked in hydraulic oil circuit.
Achieving floating status of actuator by H or J spool type.
The are ball, poppet and spool types as shuttle valve sealing type. .
DWHG series are solenoid pilot operated spool type valves.
The spool type direct acting relief valve controls the inlet pressure at main port by adjusting the presetting pressure.
Pilot operated, pressure balanced, poppet spool type.
Spool type: The spool type relief valve can flow through a larger volume but with a smaller pressure range regulation.
Little switching space position than H spool type, widely applications.
The spool type direct acting relief valve is slow to pressure response, large pressure regulating range and good operation stability.
There are some hydraulic impact from stop working to start,switching performance is between E spool type and H spool type.
The spool type hydraulic cartridge valve is sealed by a cylindrical surface of spool and there is always a gap, so leakage is inevitable.
According to the different valve poppet, hydraulic check valve canbe divided into ball valve poppet type, spool poppet type and spool type.
The spool type direct acting relief valve is a kind of spool type, pipeline(threaded) connection direct acting pressure relief valve.
The return oil flows to oil tank when the actuator stops working,there is no dampening effect of H spool type, the spool is more stable than Etype when spool switching.
Picture C-3, C-4 and C-5 are the spool type, spool with orifice type and differential spool type of direct acting relief valve.
Because oil ports of A, B and T are connected, operation actuator is in the floating state, movement or rotary can be made if there is an external force on it, therefore,the J spool type can be used in hand mechanism actuator.
Choosing G or E spool type of hydraulic spool valve to cut inlet fluid flow and quick stops actuators' movement when the spool in central position.
The inlet port P, return port T and work oil port ports A, B all connected, the hydraulic actuator is in a floating state, movement or rotary can be made ifthere an external force on it, therefore, the H spool type can be used in hand mechanism actuators.
This is 4/3(3 directional position& 4 oil porting)with different function of spool types for optional, it is usually used to control the double acting cylinder in hydraulic machines, or control the rotation way of hydraulic motor.
Such as slewing mechanism in hydraulic crane is running under heavy load, the inertia force will general a huge hydraulic shock if switching the hydraulic power too fast, therefore, the problemis able to be solved by choosing H or J spool type of hydraulic spool valve.
When H, F and G spool type in neutral position of 4way, 3postion directional spool valve, the oil fluid from pump returns to oil reservoir directly to complete unloading hydraulic oil circuit, which allows pump to work under no load or a very small output power to achieve energy saving.
The inlet and outlet ports of device are closed, hydraulic actuator can be fixed in any its' working mechanism position, and no movement or rotary further even ifthere is external force on it, therefore, the E spool type can not be used with the hand mechanism actuators.
The key part of hydraulic spool valve is spool, a spool valve function depends on the spool type, using different spool type in the middle of valve housing position will achieve different purpose in hydraulic system, therefore, appropriate function spool in middle position must be selected as per its feature during the design of hydraulic systems.
The core is usually a poppet type or a spool poppet type with very flexible control.
Picture-A4 is means ball sealing type andPicture-A5 is the spool sealing type.
The Ceymar XT series includes front drag and rear drag type with extra spool.
The valve spool is cylindrical type, there are inlet and outlet ports on the valve housing and grooves on the valve spool. .
The Coil wire comes into the form of coil wire, spool wire, U type wire or cut wire.
You need to know that directional control valves are classified according to their number of ports, the number of positions,the actuating methods and the type of spool.
