DZ/T-F

The PROTEGO® In-Line Valve DZ/T-F is a state-of-the-art Pressure or Vacuum Relief Valve for higher system pressures. Typically, the valve is installed in the in-breathing or outbreathing lines of tanks, vessels, and process equipment to protect against unallowable overpressure Surpression Overpressure refers to an increase in pressure in a system or vessel above the normal operating pressure. or underpressure. The valve prevents emission losses almost up to the set pressure Pression de réponse Set pressure is the gauge pressure at the device inlet at which the relief device is set to start opening under service conditions. and prevents unacceptable product. This springloaded model allows higher set pressures than the DZ/T.

Due to our highly developed manufacturing technology, the tank pressure Pression de la cuve Tank pressure is the pressure within a tank. 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 sturdy housing Corps A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. design. After the overpressure is released or the vacuum is balanced, the valve re-seats and provides a tight seal Joint A seal prevents or limits unwanted transfer of product from one container to another. Seal is used as superordinate term for all types of sealing elements. . The optimized fluid dynamic design of the valve body and valve pallet Clapet Valve pallet is the generic term for the assembly that rests on the valve seat. is a result of many years of research, resulting in stable operation of the valve pallet, optimized performance, and reduced product losses.
