Note: 1. The direct acting diaphragm type is limited to five specifications of DN8~DN25, while the pilot diaphragm type can be produced in all specifications;
2. The five specifications of DN8~DN25 are made of brass and 304 stainless steel, while the rest of the specifications only have brass;
3. The normally open limit DN25~DN50 can be made and needs to have a pressure difference of 0.3 bar or more, while other specifications do not have a normally open limit;
4. If there are impurities in the fluid, a filter valve (filter mesh ≥ 60 mesh) should be installed in front of the solenoid valve, and there should be no solidification or crystallization phenomenon;
5. Explosion proof coil power: AC 12VA (17VA for DN20 and DN25 in B010 grade), DC: 10W/(20W for DN20 and DN25 in B010 grade).
