DV/ZT
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-breathing and out-breathing lines of tanks, vessels and process equipment to protect against unallowable overpressure and underpressure. The valve prevents emission losses almost up to the set pressure and provides protection from product entry into the system. For structural reasons, the lower valve pallet is one size smaller than the upper valve pallet.

DV/ZU
DV/ZU
The PROTEGO® in-line valve DV/ZU is a state-of-the-art pressure and vacuum relief valve with separate flange connections for pressure and vacuum breathing. Typically, the valve is installed in the in-breathing and out-breathing lines of tanks, vessels, and process equipment to protect against unallowable overpressure and underpressure. The valve prevents emission losses almost up to the set pressure and prevents unacceptable product entry. It is designed in a way that if the set pressure is exceeded, the vapors are released into anexhaust pipe (e.g., vent header). If the set vacuum is exceeded, atmospheric air is pulled into the system. For structural reasons, the vacuum valve pallet is one size smaller than the pressure valve pallet.

DVZW-F
DVZW-F
The PROTEGO® in-line valve DV/ZW-F is a state-of-the-art pressure and vacuum relief valve with flanged connections for use in a vent line. Typically, the valve is installed in the inbreathing and out-breathing lines of tanks, vessels, and process equipment to protect against unallowable overpressure and underpressure.

DZ-T
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-breathing or out-breathing lines of tanks, vessels, and 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. The device will start to open as soon as the set pressure is reached and only requires 10% overpressure to full lift. Continuous investments in and a commitment to research and development have allowed PROTEGO® to develop a low pressure valve which has the same opening characteristic as a high pressure safety relief valve. This “full lift type” technology allows the valve to be set at just 10% below the maximum allowable working pressure or vacuum (MAWP or MAWV) of the tank and still safely vent the required mass flow. 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.

DZ/E-F
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.

DZ/T-F
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 or underpressure. The valve prevents emission losses almost up to the set pressure and prevents unacceptable product. This springloaded model allows higher set pressures than the DZ/T.

EB
EB
The PROTEGO® EB end-of-line deflagration flame arrester provides protection against atmospheric deflagration and long-lasting stabilized flames, called endurance burning. The device is typically installed on vent lines of vessels and plant equipment which is not pressurized. The device prevents flame transmission from endurance burning or atmospheric deflagration into the vessel or plant.

EB-Z
EB-Z
The PROTEGO® EB-Z end-of-line deflagration flame arrester has been successfully used to protect small vessels and process engineering apparatus which are not pressurized. The device provides protection against flame transmission through atmospheric deflagration and stabilized flames which can burn for very long time on the flame arrester element surface, so called endurance burning. Main application area is on in- and outbreathing vent lines, with the goal to prevent flame transmission caused by endurance burning or atmospheric deflagration from propagating into the vessel or plant.

EF/V-IIB3
EF/V-IIB3
The PROTEGO® EF/V-IIB3 detonation-safe foot valve protects the suction line in a storage tank. The virtually maintenancefree device is installed at the end of the emptying line within the tank. During suction, the valve opens at an approximate under-pressure of 30 mbar / 12 inch W.C. When the pump is turned off, the device functions as a check valve and prevents the line from emptying. This is very helpful when the pump is restarted.
