Stainless steel single stage pressure reducer
♦Structural features
1. Voltage regulation characteristics: the gas source pressure is in the range of 5-15 MPa, the inlet pressure changes by 1 MPa, and the outlet pressure changes by no more than 7X10-3 MPa.
2. Flow characteristics: When the inlet pressure is greater than 2 MPa, the regulated flow rate changes within the rated range, and the output pressure change is not more than ± 6% of the upper limit of the output pressure gauge.
3. Internal and external leakage rate: <5X10-9Pa.m3/s.
4, the structure is small, light weight, suitable for gas pressure regulation of the vial of 8 liters or less.
5. The diaphragm in the valve adopts a metal diaphragm to avoid secondary pollution of the high-purity gas by the rubber diaphragm.
