Notes:
1. For operation safe, must be use a tri-valve to connect with leading tube.
2. To suggest installation the two pressure ports in horizontal, to get best result.
3. To be care the static pressure ≤20MPa , range and overpressure of MDM490 shall be within the specification.
4. Other demands, please contact us and mark in the order.
