DZ/EA-F

The lined PROTEGO® in-line valve DZ/EA-F is a state-of-the-art pressure or vacuum relief valve Pressure and vacuum relief valve A pressure and vacuum relief valve is a pressure equalization valve for impermissible pressure and vacuum in a closed system. in a right angle design for higher set pressures. The lining Lining Protective plastic lining with a defined minimum/maximum thickness to protect against aggressive mixtures (e.g., acid). makes this model a perfect solution for corrosive, polymerizing, or sticky substances. All inner parts are manufactured from PTFE or other highly corrosion resistant materials. Typically, the valve is installed in the in-breathing or out-breathing lines of tanks, vessels, and 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 Overpressure 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 Set pressure 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. This springloaded model allows higher set pressures than the DZ/EA.

Due to our highly developed manufacturing technology, the tank pressure Tank pressure 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 the use of Hastelloy valve seats and with individually lapped valve pallets (1). After the overpressure is released or the vacuum is balanced, the valve re-seats and provides a tight seal Seal 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 Valve pallet 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.
