The valve prevents emission losses almost up to the set pressure and prevents air intake almost up to the set vacuum. Benefits: - 10% technology for minimum pressure increase up to full lift - extreme tightness, resulting in lowest possible product losses and reduced environmental pollution - set pressure close to opening pressure for optimum pressure maintenance in the system - very high flow capacity - valve pallet is guided inside the housing to protect against harsh weather conditions - can be used in explosion hazardous areas - automatic condensate drain - maintenance-friendly design - best technology for API tanks
PROTEGO® Detonation Flame Arresters
The in-line detonation flame arresters type PROTEGO® DA-SB are the newest generation of flame arresters. Based on flow and explosion dynamic calculations as well as decades of field tests, a product line was developed that offers minimum pressure losses with maximum safety. The flame arrester uses the Shock Wave Guide Tube Effect (SWGTE) to separate the flame front and shock wave. The result is an in-line detonation arrester without a classic shock absorber, which minimizes the use of FLAMEFILTER® discs. Benefits: - optimized performance due to the patented Shock Wave Guide Tube Effect (SWGTE) - low number of FLAMEFILTER® discs due to the patented Shock Wave Guide Tube Effect (SWGTE) - modular design enables replacement of the individual FLAMEFILTER® discs - different designs allow scalable pressure loss over the area of the FLAMEFILTER® - maintenance-friendly design - advanced design for higher operating temperatures and pressures - bi-directional operation, as well as any flow direction and installation position - installation of temperature sensors possible - minimal pressure loss resulting in low operating and lifecycle costs - cost-effective spare parts - installation of stabilized FLAMEFILTER® possible - use of maintenance-friendly PROTEGO® flame arrester unit possible
PROTEGO® Deflagration Flame Arresters, end-of line and Vent Caps
The PROTEGO® LH/AD end-of-line deflagration flame arrester provides protection against flame transmission through atmospheric deflagration. The device is typically installed on vent lines of vessels and plant equipment which are not pressurized. For safe application, it is important that an endurance burning situation can be excluded. So typically, it is installed on vent lines which discharge vapor for a short time period. The device prevents flame transmission from atmospheric deflagration into the vessel or plant. Benefits: - weather hood with protection screen protects the PROTEGO® flame arrester unit against environmental impact, such as nesting animals and weather conditions - available for DN 50/2“- bis DN 800/32“- pipes - trouble-free maintenance - advanced design for higher operating temperatures - provides protection against atmospheric deflagrations - low operating and lifecycle costs - cost-effective flame arrester - cost-effective spare parts
PROTEGO® Deflagration Flame Arresters
The PROTEGO® FA-CN in-line deflagration flame arrester is a compact design utilizing an easy access cover for easy maintenance. The PROTEGO® flame arrester unit can easily be removed and cleaned in just a few simple steps without having to disassemble the pipe. When installing the deflagration flame arrester, make sure that the distance between potential ignition sources and the location of the installed device does not exceed the L/D ratio (pipe length/pipe diameter) for which the device was tested. According to EN ISO 16852, this device is approved for a (L/D)max ratio of 50. Benefits: - design available for elevated operating temperatures and pressures - compact design with easy access cover - easy maintenance without disassembling of the pipeline - modular flame arrester unit enables individual FLAMEFILTER® to be replaced and cleaned - bi-directional flame transmission proof design - provides protection against deflagrations for group IIA and IIB3 vapours (NEC group D and C) - lowest pressure drop results in low operating and lifecycle costs - modular design reduces spare parts cost
PROTEGO® Pressure/Vacuum Relief Valves with Flame Arrester, end-of-line
The atmospheric deflagration-proof VD/TS type PROTEGO® valve is a highly developed combined pressure/vacuum relief valve for high flow capacities with an integrated flame arrester unit. It is primarily used as a device for flame transmission proof in-breathing and out-breathing on tanks, containers, and process equipment. The valve offers reliable protection against overpressure and vacuum, prevents the in-breathing of air and product losses almost up to the set pressure, and protects against atmospheric deflagration. The PROTEGO® flame arrester unit is designed to achieve minimum pressure drop with maximum safety. The PROTEGO® VD/TS device is available for substances from explosion groups IIA to IIB3 (NEC group D to C MESG ≥ 0.65 mm). Benefits: - 10% technology for minimum pressure increase up to full lift - extreme tightness, resulting in lowest possible product losses and reduced environmental pollution - due to 10% technology, set pressure is close to opening pressure for optimum pressure maintenance in the system as compared to conventional 40% or 100% technology - valve pallet is guided inside the housing to protect against harsh weather conditions - can be used as a protective system in areas with potentially explosive atmospheres in accordance with ATEX - FLAMEFILTER® provides protection against atmospheric deflagrations - integrated flame arrester unit saves space and reduces costs - PROTEGO® flame arrester unit is protected from clogging and sticky products caused by product vapors - minimum pressure loss of the PROTEGO® flame arrester unit - high flow capacity - maintenance-friendly design - sturdy housing design - best possible technology for API tanks
PROTEGO® Tank Equipment
PROTEGO® Floating Suction Units, FSU, are used in storage tanks with very high purity requirements of the substances, e.g., aviation or fossil fuels. They are designed to ensure that product in a storage tank is drawn off just below the surface of the liquid where it is cleanest. This prevents the settled water and residuals at the bottom of the tank from being sucked in.
PROTEGO® Pilot-operated P/V Valve
The PROTEGO® Type VN-A-PCPF pilot-controlled diaphragm valve is a newly developed valve for pressure and vacuum relief. It is primarily used as a device for out-breathing in tanks, containers, and process equipment. It provides protection against vacuum and overpressure and prevents the intake of air and unallowable product vapor loss up to the set pressure. The valve can also be used as an in-breathing valve where the main valve is directly controlled when it is exposed to a vacuum, i.e., it functions as a weight-loaded diaphragm valve. Benefits: - controlled by corrosion-resistant control valve (pilot valve) - small amounts of tank substance is released into the atmosphere when the valve is opened - max. 10% pressure increase up to full lift - extreme tightness, resulting in lowest possible product losses and reduced environmental pollution - set pressure close to opening pressure for optimum pressure maintenance in the system - protection of the main valve control diaphragm from low temperatures – high durability - high flow capacity - can be used in explosion hazardous areas - field test connection possible upon request - field test kit upon request
PROTEGO® In-Tank Valve
PROTEGO® ITV-S in-tank valves are used in storage tanks for cryogenic liquids in order to seal off discharge lines in the event of an accident or emergency. These devices meet the requirements of API 625. The PROTEGO® ITV-S consists of a valve guide unit with elbow and valve seat which is mounted on the inside of the tank wall. This unit accommodates the valve piston and guides it over the entire lift stroke. The seal between the valve seat and the valve disk is ensured by finely lapped surfaces and achieves maximum tightness. The actuating unit, installed on the tank roof, is specifically designed for the requirements of the application and connected to the valve unit installed in the tank via suitable cables. During normal operation, the valves are kept in the open position. The bottom valve is only closed in an emergency. In the event of an energy drop, the valve piston, due to its own weight, falls onto the valve seat which closes the bottom valve (fail safe concept). The PROTEGO® ITV-S design provides the tank designer and the user with the following benefits: - Very light and compact design - Connection to the tank wall via flange connection - No support or guidance required in the tank - Low forces required for lifting the valve piston - Extremely high tightness due to metallic sealing surfaces
