LD30W series self operated micro pressure regulating valve
| High safety: Used in non electrical environments, there are no external energy hazards. The nitrogen sealing device is easy to set for nitrogen supply and release pressure, and can be operated under continuous production conditions. The nitrogen supply device is operated by a commander, with a pressure reduction ratio of up to 100:1, good pressure reduction effect, and high control accuracy. A breathing valve is required for top filling to ensure safety and avoid the frequent opening and closing and easy damage defects of conventional nitrogen sealing devices | Valve body parameters |
