PN25 (max. Pressure 25bar at 100 ° C, max. 20bar at 130 ° C)

PN16 (with olive seal ring and nut mounting kit (max. 16bar at 30 ° C, 5bar at 120 ° C)

Working environment:

● Medium (water): -10 ° C to 130 ° C

(Maximum temperature to 120 ° C with olive seal and nut mounting kit)

Below 0 ° C only for aqueous media (with antifreeze)

Above 100 ° C is only suitable for aqueous media (with anti-boiling additive)

Product Highlights:

1. High-grade brass precision forging, the valve parts are compact:

2.Kvsu21m3/h is suitable for any size fan tray camp:

3. Straight water flow will never block the slag:

4. Large water circulation capacity, higher than traditional valve 3 or more

5. The valve is closed tightly and there is no internal leakage.

6. The drive will be powered off automatically after the valve is closed/opened. long lasting:

7. The closed structure is subject to gas intrusion. The motor runs reliably:

8. Can be mounted upright or horizontally

9. The failure rate is extremely low.
