Function and Description
Pressure or Vacuum Relief Valve in Corner Design Made of Plastic
The PROTEGO® In-Line Valve R/KSM is a state-of-the-art Pressure or Vacuum Relief Valve in a right angle design made out of high-grade synthetic material. Typically, the valve is installed in the in-breathing or out-breathing lines of tanks, vessels, and process

Lift is the actual travel of the valve pallet from the main valve out of the closed position.
. Continuous investments in and a commitment to 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 at just 10% below the maximum allowable working pressure or
