PROTEGO®
Pressure and Vacuum Relief Valves with Flame Arrester
Reliable tank protection with controlled venting and explosion protection
Pressure and Vacuum Relief Valves with integrated Flame Arrester Flammendurchschlagsicherung Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a flame. Unit combine two critical safety functions into a single unit: controlled tank breathing and protection against flame transmission. This configuration is widely used in storage tank systems handling flammable vapours, where both pressure and vacuum Unterdruck Vacuum is the pressure in an enclosed space that is lower than the ambient pressure. protection and ignition risk must be addressed in a compact, engineered solution.

Lorem Ipsum Zero Emissions with PROTEGO® Breather Valves
Lorem IpsumThe extreme tightness of PROTEGO® Valves guarantees Zero Emission at Tank Operating Pressure.
Due to the highly developed manufacturing technology of PROTEGO® valves the tank pressure Tankdruck Tank pressure is the pressure within a tank. is maintained up to set pressure Ansprechdruck Set pressure is the gauge pressure at the device inlet at which the relief device is set to start opening under service conditions. with a tightness that is far superior to the conventional standard. According to the PROTEGO® Standard PS-001 leak rates are measured at 90% of the set pressure. This testing ensures PROTEGO® Valves exceed the most stringent leakage rate requirements of EPA, API2000 and EN ISO 28300.

technology. This technology provides very short opening and closing pressure ranges. The vent only requires 10% overpressure above the set pressure to reach full performance. The tank pressure is maintained up to just below the maximum permissible tank pressure.
PROTEGO® 10% full-lift technology vents are a major benefit to emission reduction and to safe process plant operation.
The devices have performed as promised with low leak rates and minimal maintenance effort. We highly recommend them.

Engineering and Compliance
Correct valve selection is critical for safe and effective operation. Key selection criteria include:
Function
Operating principle
Design type
Sealing type
Operating conditions
Valve sizing is based on required volume flow and maximum allowable pressure. Certified volume flow diagrams are available to support design.
Sizing must also account for:
Pressure losses in connected piping
Other installed devices
External backpressure effects
Key Features and Design Characteristics
The valve reaches full lift within 10% overpressure. This enables set pressure close to opening pressure, improving pressure control and reducing product Produkt Includes equipment, protective systems, devices, components and combinations of these. losses compared to conventional designs.
The sealing system maintains tightness above normal standards. This minimizes vapor loss and helps maintain system pressure up to the point of opening.
The valve opens later and re-seats earlier than conventional valves. This improves pressure stability and reduces loss of product or inert gas Inertgas Non-flammable gas which will not support combustion and does not react to produce a flammable gas. .
Large volume flows are achieved with only a small pressure difference. This supports efficient venting and can reduce the need for larger valve sizes.
The valve pallet Ventilteller Valve pallet is the generic term for the assembly that rests on the valve seat. is guided within the housing Gehäuse A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. . This protects internal components from environmental exposure and supports consistent operation.
The valve design allows for straightforward maintenance Instandhaltung Combination of all technical and administrative actions, including supervision actions, intended to maintain or restore a unit in working order. , supporting long-term operation.
The valves are suitable for use in explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. hazardous areas, supporting installation in regulated environments.
