Unique feature and use:
1. this reed valve structure is compact, the volume is small, the weight is light, the operation is flexible, the service is convenient. 2. the design uses three biased seal principle, the sealing property to be reliable. 3. seals vice-selects the stainless steel material, and carries on special craft processing in the process of manufacture, has is thermostable, is anti-corrosive, service life long characteristic. 4. the overflow area is big, the resistance to flow coefficient is small, the flow capacity is big. 5. the anti-aging, does the radiation, durable.
