Notes:

1.  Please refer to “Features of Coil” for the electromagnetic coil.

2.  When selecting the tapered plug applied into valve port to reduce flow rate, please indicate the hole size (mm) of the tapered plug.

3.  When selecting A/B/AB adjustment type, please refer to the table of “Statement of Model No. of Proportional Adjustment & Manual Switch Installed Solenoid Valve”.

4.  B-type valve can reduce current effectively, even energy-saving.

5.  B-type valve can reach the high flow and pressure as the same as E-type.

6.  Low temperature raise and can increase the life of hydraulic components.

7.  All valves are with wider port size to improve the flow capacity.

8.  The B/E solenoid valves conform to the international standard and totally interchangeable.

Notes：

1.  All the coils can be operated within ±10% the rated voltage.

2.  Special voltage requirements are also available.

 

Temperature Rise Performance for B Type vs. E Type

1.  The operation pressure is 100kgf/em² in the coil temperature test.

2.  The test is at a constant temperature of 25°C.

3.  Using AC220V coil for this test.

 

The Features of B and E Solenoid Valve

1.  Dual line tank design reduces the pressure drop resulting in better flow characteristics.

2.  The spool’s design is the increased size and can improve the better flow characteristics Huge increasing of back-pressure allowable and lower internal resistance.

3.  New special design type coil can lower current effectively, even energy-saving, also able to reach the high flow and pressure as the same as E type. Please refer to “Pressure drop curve” for a reference.

4.  The valve’s feature and dimensions are as the same as E-type.

5.  The B-type solenoid valve will improve your product quality and increase the company’s competitiveness.
