PROTEGO® 呼吸阀

减少排放 - 运营安全

存储液体物质的封闭容器或储罐，压力控制非常重要。为保障安全，储罐内的超压和真空必须得到释放。PROTEGO® 呼吸阀满足容器或储罐对压力控制的要求。这类阀门，无论是重块负载或弹簧负载式，对储罐压力控制起到至关重要的作用。

无论超压还是真空，比如因储罐进料、出料、蒸汽清扫或热呼吸，PROTEGO®呼吸阀给您提供最佳方案。我们可以提供呼吸阀、单呼阀或单吸阀。

来自油气行业，炼油和化工行业，制药和生物能源等行业的客户高度信赖PROTEGO阀门，确保装置安全有效运营。我们阀门因先进的设计，高效的作用，赢得客户信任，得到广泛的应用。

Diaphragm Valves

PROTEGO® Diaphragm Valves function as pressure vacuum relief valves. The flexible diaphragm allows them to work as a dynamic flame arrester which provides endurance burning protection. For additional safety, these devices are equipped with a static flame arrester unit.

For extreme cold weather conditions

A specially designed valve seat, combined with the flexible diaphragm, prevents the diaphragm from freezing on the valve seat.

For problematic products

The only vent which works reliably with problem products such as Styrene or Acrylates.

Emergency Relief Valves

Emergeny relief valves offer reliable protection against overpressure and prevent impermissible product vapor loss close to the set pressure.

Emergency Pressure Relief

Used as a device for emergency pressure relief for storage tanks, containers, silos, and process engineering equipment.

Excellent Tightness

Excellent tightness and hence least possible product losses and reduced environmental pollution.

Pilot-Operated Valves

PROTEGO® pilot-operated valves provide protection against vacuum and overpressure and prevent the intake of air and unallowable product vapor loss up to the set pressure.

Extreme Tightness

Lowest possible product losses and reduced environmental pollution due to our highly developed manufacturing technology.

Tank pressure is maintained up to the set pressure

The set pressure is close to the opening pressure for optimum pressure maintenance in the system.
