Model: ER/V The ER/V type PROTEGO valve is a highly developed emergency pressure relief valve with high flow capacity. It is primarily used as a safety device for emergency pressure relief for storage tanks, containers, silos, and process engineering equipment; it offers reliable protection against overpressure and prevents impermissible product vapour loss close to the set pressure. It is designed to relief particularly large amounts to prevent the vessel from rupturing in an emergency case. |

Model: ER/VH The ER/VH type PROTEGO valve is a highly developed emergency pressure relief valve with high flow capacity. It is primarily used as a safety device for emergency pressure relief for storage tanks, containers, silos, and process engineering equipment; it offers reliable protection against overpressure and prevents impermissible product vapour loss close to the set pressure. It is designed to discharge particularly large amounts to prevent the vessel from rupturing in an emergency case. Higher set pressures are achieved by a lever with lockable weight loading. The position of the weight is factory-marked. Starting at DN 500, the devices can also be used as manhole covers. |

Model: ER/V-F The ER/V-F type PROTEGO valve is a highly developed emergency pressure relief valve with high flow capacity. It is primarily used as a safety device for emergency pressure relief for storage tanks, containers, silos, and process engineering equipment; it offers reliable protection against overpressure and prevents impermissible product vapour loss close to the set pressure. It is designed to discharge particularly large amounts to prevent the vessel from rupturing in an emergency case. The spring-loading allows for higher set pressures than those with the ER/V or ER/VH. |

Vacuum Relief Valves, weight pallet type
Model: SV/E-1-0 The SV/E-1-0 type PROTEGO valve is a highly developed vacuum relief valve with excellent flow performance. It is primarily used as a safety device for relieving vacuum in tanks, containers and process engineering equipment. The valve offers reliable protection against vacuum, and prevents inbreathing of air close to the set pressure. |

Model: SV/T-0-H The SV/T-0-H type PROTEGO® valve is a highly developed vacuum relief valve with a valve housing that comes with a heating jacket down to the flange. It is primarily used as a safety device for inbreathing to tanks, containers, and process engineering equipment under difficult operating conditions. This includes extreme weather conditions or products that tend to form polymers at certain temperatures, adhere, or form deposits that negatively influence function (such as bitumen, tar, dust). The valve offers reliable protection against vacuum and prevents the intake of air close to the set vacuum. |

Model: V/KSM The PROTEGO® valve V/KSM is a state-of-the-art vacuum relief valve with excellent flow performance made of high grade synthetic material. It is used as a safety device to relieve vacuum in tanks, containers, and process engineering equipment; it prevents the inbreathing of air until reaching the set vacuum. The valve is a perfect solution for corrosive, polymerising or sticky media. |

Pressure and Vacuum Relief Valves, weight pallet type
Model: PV/EL The PV/EL type PROTEGO valve is a highly developed combined pressure and vacuum relief valve. It is primarily used as a safety device for relieving pressure and vacuum in tanks, containers and process engineering equipment. The valve offers reliable protection against overpressure and excessive vacuum. It also prevents the impermissible loss of product vapours close to the set pressure as well as the intake of air on the vacuum side close to set vacuum. |

Pressure Relief and Vacuum Valve, pilot-operated
Model: PM/(D)S The PM/(D)S type pilot-controlled PROTEGO diaphragm valve is a highly developed valve for pressure and vacuum relief. It is primarily used as a safety device for outbreathing in tanks, containers, and process engineering equipment and it also offers reliable protection from vacuum and overpressure. It prevents the intake of air and unacceptable product vapour loss up to the set point. The valve can also be used as inbreathing valve. The main valve is directly controlled when it is exposed to a vacuum; i.e., it functions as a weight-loaded diaphragm valve. This valve is highly suitable under atmospheric conditions and for use in cryogenic service. |
