Pressure or Vacuum Relief Valves

Model: DZ/E
The PROTEGO in-line valve DZ/E is a state-of-the-art pressure or vacuum relief valve in right angle design. Typically the valve is installed in the in- or outbreathing lines of tanks, vessels and process apparatus to protect against unallowable high or low pressure. The valve prevents emission losses almost up to the set pressure or provides protection from product entry into the system.
Model: DZ/E-F
The PROTEGO in-line valve DZ/E-F is a state-of-the-art pressure or vacuum relief valve in right angle design for higher system pressures. Typically the valve is installed in the in- or outbreathing lines of tanks, vessels and process apparatus to protect against unallowable high or low pressure. The valve prevents emission losses almost up to the set pressure or provides protection from product entry into the system. As this device is equipped with a spring higher set pressures can be reached compared to the DZ/E.
Model: DZ/EA
The lined PROTEGO in-line valve DZ/EA is a state-of-the-art pressure or vacuum relief valve in right angle design. The lining makes this model a perfect solution for corrosive, polymerizing or sticky media. All internal parts are manufactured from PTFE or other highly corrosion resistant materials. Typically the valve is installed in the in- or out-breathing lines of tanks, vessels and process apparatus to protect against unallowable high or low pressure. The valve prevents emission losses almost up to the set pressure or provides protection from product entry into the system.
Model: DZ/EA-F
The lined PROTEGO in-line valve DZ/EA-F is a state-of-the-art pressure or vacuum relief valve in right angle design for higher set pressures. The lining makes this model a perfect solution for corrosive, polymerizing or sticky media. All internal parts are manufactured from PTFE or other highly corrosion resistant materials. Typically the valve is installed in the in- or out-breathing lines of tanks, vessels and process apparatus to protect against unallowable high or low pressure. The valve prevents emission losses almost up to the set pressure or provides protection from product entry into the system. This spring loaded model allows higher set pressures than the DZ/EA.
Model: DZ/T
The PROTEGO in-line valve DZ/T is a state-of-the-art pressure or vacuum relief valve. Typically the valve is installed in the in- or out-breathing lines of tanks, vessels and process apparatus to protect against unallowable high or low pressure. The valve prevents emission losses almost up to the set pressure or provides protection from product entry into the system.
Model: 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- or out-breathing lines of Tanks, Vessels and process apparatus to protect against unallowable high or low pressure. The valve prevents emission losses almost up to the set pressure or provides protection from product entry into the system. As this device is equipped with a spring higher set pressures can be reached compared to the DZ/T.
Model: R/KSM
The PROTEGO in-line valve R/KSM is a state-of-the-art pressure or vacuum relief valve in right angle design made out of highgrade synthetic material. Typically the valve is installed in the in- or out-breathing lines of tanks, vessels and process apparatus to protect against unallowable high or low pressure. The valve prevents emission losses almost up to the set pressure or provides protection from product entry into the system. The valve is a perfect solution for corrosive, polymerizing or sticky media.

 

Pressure and Vacuum Relief Valves

Model: DV/ZT
The PROTEGO in-line valve DV/ZT is a state-of-the-art pressure and vacuum relief valve. Typically the valve is installed in the in- and out-breathing lines of tanks, vessels and process apparatus to protect against unallowable high and low pressure. The valve prevents emission losses almost up to the set pressure and provides protection from product entry into the system. Due to its design the lower valve pallet is one size smaller than the upper valve pallet.
Model: DV/ZT-F
The PROTEGO in-line valve DV/ZT-F is a state-of-the-art pressure and vacuum relief valve. Typically the valve is installed in the in- and out-breathing lines of tanks, vessels and process apparatus to protect against unallowable high and low pressure. The valve prevents emission losses almost up to the set pressure and provides protection from product entry into the system. Due to its design the vacuum valve pallet is one size smaller than the pressure valve pallet. Due to the spring loaded design higher set pressures can be achieved.
Model: DV/ZU
The PROTEGO in-line valve DV/ZU is a state-of-the-art pressure and vacuum relief valve with separate fl ange connections for pressure and vacuum breathing. Typically the valve is installed in the in- and outbreathing lines of tanks, vessels and process apparatus to protect against unallowable high and low pressure. The valve prevents emission losses almost up to the set pressure and prevents air intake almost up to set vacuum. The valve is designed so that in cases in which the set pressure is exceeded the vapours are vented into a discharge pipe (i.e. vent header). When the set vacuum is exceeded atmospheric air is pulled into the system. Due to its design the vacuum valve pallet is one size smaller than the pressure valve pallet.
Model: DV/ZW
The PROTEGO in-line valve DV/ZW is a state-of-the-art pressure and vacuum relief valve with separate fl ange connections for use in a vent line. Typically the valve is installed in the in- and outbreathing lines of tanks, vessels and process apparatus to protect against unallowable high and low pressure. The valve prevents emission losses almost up to the set pressure and prevents air intake almost up to set vacuum. The valve is designed so that in cases in which the set pressure is exceeded the vapours are vented into a discharge pipe (i.e. vent header). When the set vacuum is exceeded atmospheric air is pulled into the system. Due to its design the vacuum valve pallet is one size smaller than the pressure valve pallet.

 

Blanketing Valve

Model: ZM-R
The blanketing valve type ZM-R is a highly developed low pressure reducing valve. This valve is typically used to inert or blanket tanks, vessels or other process systems with nitrogen or other blanketing gases by controlling the tank pressure to its desired value. High nitrogen or blanketing gas supply pressures up to 16 bar / 232 psi are safely reduced down to only a few mbar / In W.C..

The ZM-R low pressure reducing valve is a direct acting one stage pressure control device. It is designed as a membrane
controlled, spring loaded proportional acting valve. The valve controls the tank pressure by increasing fl ow as the tank pressure drops. This means that the mass fl ow through the device depends on the pressure differential of the set pressure to the actual tank pressure. When the actual tank pressure reaches the set pressure the control unit closes and there is no flow.
