D/SVL Pressure Relief Valve

Brand: PROTEGO
The D/SVL type Protego valve is a high performance pressure relief valve. 

It is primarily used as a safety device for relieving pressure in tanks, containers, and process engineering equipment. 

The valve offers reliable protection against over-pressure and prevents the unacceptable loss of product vapors close to the set pressure. 

The device will start to open as soon as the set pressure is reached and only requires 10% overpressure to full lift. 

Continuous investments into research and development have allowed Protego to develop a low pressure valve which has the same opening characteristic as a high pressure safety relief valve. 

This "full lift type" technology allows the valve to be set just 10% below the maximum allowable working pressure of the tank and still safely vent the required mass flow.
Features
  • "Full lift type" technology valve utilizes only 10% overpressure to reach full lift
  • Extreme tightness and hence least possible product losses and reduced environmental pollution
  • The set pressure is close to the opening pressure which results in best possible pressure management of the system
  • Extremely high flow capacity
  • The valve pallet is guided within the housing to protect against harsh weather conditions
  • Can be used in areas subject to an explosion hazard
