DWHG series are solenoid pilot operated spool type valves.
The are ball, poppet and spool types as shuttle valve sealing type. .
Achieving floating status of actuator by H or J spool type.
The G spool type is used for pump unloading and cylinder locked in hydraulic oil circuit.
Little switching space position than H spool type, widely applications.
Spool type: The spool type relief valve can flow through a larger volume but with a smaller pressure range regulation.
WEH series solenoid pilot operated DirectionalValves 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.
There are some hydraulic impact from stop working to start,switching performance is between E spool type and H spool type.
The spool type direct acting relief valve is slow to pressure response, large pressure regulating range and good operation stability.
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.
The spool type direct acting relief valve is a kind of spool type, pipeline(threaded) connection direct acting pressure 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.
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.
However kindly inform you that Coriolis mass flow meter is much more expensive than thermal mass, so it is more economic andcheaper to choose Thermal dispersion flanged spool type flowmeter for both N2 flow measurement and He flow measurement.
The spool type hydraulic cartridge valve is sealed by a cylindrical surface of spool and there is always a gap, so leakage is inevitable.
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 problem is able to be solved by choosing H orJ spool type of hydraulic spool valve.
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 if there an external force on it, therefore,the H spool type can be used in hand mechanism actuators.
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 if there 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 horn type spool winder is suitable for winding Y-type cone.
And the bobbin can be cone type, king spool, cylinder type, etc….
Picture-A4 is means ball sealing type andPicture-A5 is the spool sealing type.
And we can offer spool and straight type, whose diameters are all above 0.05 mm.
The valve spool is cylindrical type, there are inlet and outlet ports on the valve housing and grooves on the valve spool. .
The soft black ironwire 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.
There are two types of the valve spool, ball type, and poppet type. .
