Q&A

What Is a Pilot Operated Breathing Valve?

This advanced pressure control device is installed on storage tanks and regulates internal pressure by releasing excess vapor and allowing air intake during vacuum conditions. It regulates internal pressure by releasing excess vapor and allowing air intake during vacuum conditions.

Unlike conventional breathing valves, the pilot operated design improves response speed and sealing accuracy. As a result, it reduces product loss while maintaining safe tank operation.

Furthermore, this valve combines pressure balance technology with flame protection features. It provides a reliable solution for industries handling volatile liquids and gases.

Key Features of GMK Valve Advanced Breathing Valve System

The GMK Valve ZCPE series provides multiple advantages for industrial storage systems.

First, the advanced pilot control structure keeps the seat leakage near the set point. Therefore, the valve improves sealing performance and reduces unnecessary vapor loss.

In addition, the valve provides full flow capacity without overpressure. This feature helps protect tanks from pressure fluctuations and improves system reliability.

Moreover, the valve uses vapor heat transfer principles to reduce freezing risks. As a result, the internal components can maintain normal operation in cold environments.

The sealing components use high-quality PTFE materials. Therefore, the valve offers excellent low-temperature resistance, corrosion resistance, and anti-frost performance.

Furthermore, the electrostatic protection device keeps the valve and tank at the same potential. This design improves safety during long-term operation.
