Features and application: 1. Purpose: This series of valves can be widely used in the production and living water, fire water supply, water supply and other high-rise buildings require decompression of the pipeline system. 2. Features: Small size, simple structure, reliable operation; dynamic pressure can also be reduced by static; decompression accurate.

The main performance parameters: ◆ Nominal pressure: PN1.6Mpa ◆ Nominal diameter: DN15 ~ 150mm ◆ decompression ratio: 4:1,3:1,2:1 or by user request ◆ Suitable temperature: ≤ 80 ℃ ◆ Suitable medium: water ◆ Flange dimension performance standards: GB17241.6 ◆ Connection: flange / female
