    Pilot Operated Safety Valve
  • Commonly used in petroleum, natural gas, electric power, metallurgy, and burning gas applications, these valves ensure bubble‑tight shut‑off under normal conditions and provide emergency relief during overpressure events.

Pilot‑Operated Safety Valve – Features

  • Easy operation
  • Only the pilot needs to be set
  • Blowdown can be externally adjusted

How It Works

The pilot valve senses system pressure and controls the main valve accordingly. When pressure exceeds the set limit, the pilot actuates the main valve, allowing excess pressure to escape. Once the system pressure returns to safe levels, the main valve closes tightly, ensuring leak‑free operation and continuous protection.
