Function and Description

Combined Pressure and Vacuum Relief Valve

The Deflagration-Proof and Endurance-Burning-Proof PV/EBR-E type PROTEGO® valve is a highly developed combined pressure/ vacuum relief valve Válvula de vacío A vacuum relief valve is used to ventilate a part of the system and protects it from impermissible underpressure. for high fl ow capacities with an integrated Flame Arrester Apagallamas 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. that is specially used for applications handling ethanol. It is primarily used as a device Bastidor A device is a pipe component that influences the media flow by opening, closing, or partially shutting off the flow channel or by dividing or mixing the media flow. for flame transmission proof outbreathing on tanks, containers and process engineering apparatus. The valve offers reliable protection against excess pressure and vacuum Vacío Vacuum is the pressure in an enclosed space that is lower than the ambient pressure. , prevents the inbreathing of air and product Product Includes equipment, protective systems, devices, components and combinations of these. losses almost up to the set pressure Presión de reacción Set pressure is the gauge pressure at the device inlet at which the relief device is set to start opening under service conditions. and also protects against atmospheric defl agration as well as endurance burning Endurance burning Stabilized burning for an unlimited time. if stabilized burning Stabilized burning Steady burning of a flame stabilized at, or close to the flame arrester element. occurs.

For Explosion Group IIB3

The PROTEGO® Flame Arrester Unit is designed to achieve minimum pressure drop with maximum safety. The PROTEGO® PV/EBR-E valve is available for substances of explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. group IIB3 (MESG ≥ 0,65 mm) and provides specific protection against defl agration and endurance burning of alcohol/air mixtures (such as Ethanol/air). The valve functions proportional, so the set pressures should be selected in relation to the proportional behaviour (such as a 10%, 40%, or 100% overpressure Presión excesiva Overpressure refers to an increase in pressure in a system or vessel above the normal operating pressure. from the set pressure to the relieving pressure Presión de apertura The relieving pressure is the vacuum or overpressure at which the valve reaches the lift required for the mass flow to be discharged. at which the required flow performance is reached).

Advanced Manufacturing Technology

The tank pressure Presión del tanque Tank pressure is the pressure within a tank. is maintained up to the set pressure with a tightness that is far superior to the conventional standard due to our state of the art manufacturing technology. This feature is ensured by the valve seats made of high quality stainless steel and with individually lapped valve pallets (1) or with an air cushion seal Sello 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. (2) in conjunction with high quality FEP diaphragm Membrana A diaphragm is a thin layer of material, which has a large surface area. . The valve pallets are also available with a PTFE seal to prevent the valve pallets from sticking when sticky products are used and to enable the use corrosive fluids. After the excess pressure is discharged, the valve reseats and provides a tight seal.

Main Component – PROTEGO® Flame Arrester Unit

If the set pressure is exceeded, explosive gas/product-vapour air mixtures are released to the atmosphere. If this mixture ignites, the integrated PROTEGO® Flame Arrester Unit (3) prevents flame transmission into the tank. If additional mixture continues to flow and stabilized burning occurs, the integrated Flame Arrester Unit prevents flashback Flashback Phenomenon occurring in a flammable mixture of air and gas when the local velocity of the combustible mixture becomes less than the flame velocity, causing the flame to travel back to the point of mixture. as a result from endurance burning. The valve is protected and also fulfils its function under this severe service conditions. The spring Amortiguador A spring is a spiral of wire which returns to its original shape after it is pressed or pulled. loaded weather hood Cubierta de protección contra la intemperie A weather hood is a cover to protect the internal components of a device from environmental influences. opens as soon as the fusible element (4) melts.

Many Individual Certifications

The valve can be used up to an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. of +60°C / 140°F and meets the requirements of European Tank Design Standard EN 14015 – Appendix L and ISO 28300 (API 2000). EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
