Hydraulic solenoid valve does not seal compactly broadly has the following various views:

1. Elastic sealing material

The elastic sealing material as per to the distinct media for assistance the design, this is not a problem, such as PTFE, EPDM, FKM, but the price gap is large, of course, here relates to the purity of the monomer which material proportion of more than 95%, most of them are renovated material.

2. Receptive sealing processing conviction

The machining conviction for mini hydraulic solenoid valve manage precision and the elastic component of it, but if it is large diameter solenoid valve elastic shape of the piece is not small, water, etc. will shrink, gate product flatness, roughness immediately adverse the current, abroad are integral forming, laser cutting etc

3. Machining precision of metal sealing touch surface and structural design. Of course, we can not say which design is best, can only be utilize in in union with the use of their elastic pieces, but the accuracy must be needed.

4. Plunger assembly welding

The overall shape of the plunger collection is small, the requirements of argon arc welding and laser welding are relatively high, one is to assure the production capacity, but also to assure the quality.
