DZ/E-F

The PROTEGO® In-Line Valve DZ/E-F is a state-of-the-art Pressure or Vacuum Relief Valve in a right angle design for higher system pressures. Typically, the valve is installed in the in-breathing or out-breathing lines of tanks, vessels, and opening pressure which results in best possible process equipment to protect against unallowable overpressure or underpressure. The valve prevents emission losses almost up to the set pressure and prevents unacceptable product entry. As this device is equipped with a spring, higher set pressures are achieved than with the DZ/E.

The opening characteristic is the same for pressure and vacuum relief. Due to our highly developed manufacturing technology, the tank pressure is maintained up to set pressure with a tightness that is far above the conventional standard. This feature is ensured by valve seats made of high quality stainless steel and with individually lapped valve pallets (1) and a sturdy housing design. After the overpressure is released or the vacuum is balanced, the valve re-seats and provides a tight seal. The optimized fluid dynamic design of the valve body and valve pallet is a result of many years of research, resulting in stable operation of the valve pallet, optimized performance, and reduced product losses.
