Suitable medium include water, sewage, sea water, steam, air, foodstuff, oils, nitric acid, strong oxidizing medium and urea etc.
Structure Performance:
1.Structure length is short.
2.Small volume, light weight.
3.Unobstructed channel, small fluid resistance.
4.Action is sensitive, sealed performance is good.
5.Simple and compact structure, attractive appearance.
6.Long using life and high reliability.
