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 Equipment Machines, appliances, fixed or mobile devices, control parts and accessories, and warning and prevention systems, whether separate or combined, intended for the generation, transfer, storage, measurement, control, and conversion of energy, and for the processing of materials, which have their own potential source of ignition and may cause an explosion. to protect against unallowable overpressure Presión excesiva 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 Presión de reacción 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 Product Includes equipment, protective systems, devices, components and combinations of these. entry. As this device Bastidor A device is a pipe component that influences the media flow by opening, closing, or partially shutting off the flow channel or by dividing or mixing the media flow. is equipped with a spring Amortiguador A spring is a spiral of wire which returns to its original shape after it is pressed or pulled. , 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 Presión del tanque 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 a sturdy housing Carcasa 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 Sello 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 Disco de la válvula 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.
