Function and Description

Highly Developed Vacuum Relief Valve
The PROTEGO® valve V/KSM is a state-of-the-art
vacuum relief valve
Vacuum relief valve
A vacuum relief valve is used to ventilate a part of the system and protects it from impermissible underpressure.

Device
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.

Vacuum
Vacuum is the pressure in an enclosed space that is lower than the ambient pressure.

Equipment
Machines, appliances, fixed or mobile devices, control parts and accessories, and warning and prevention systems, whether separate or combined, intended for the generation, transfer, storage, measurement, control, and conversion of energy, and for the processing of materials, which have their own potential source of ignition and may cause an explosion.
. It prevents the in-breathing of air until reaching the set pressure. The valve is a perfect solution for corrosive, polymerizing, or sticky substances.

Full Lift Technology
The device will start to open as soon as the set pressure is reached and is fully open within 10% pressure increase. 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 vacuum (MAWV) of the tank and still safely vent the required mass flow.
Advanced manufacturing technology
Due to our highly developed manufacturing technology, the

Seal
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.
that is far superior to the conventional standard. This feature is achieved by valve seats made of high-performance plastics and a high grade PTFE seal. After the vacuum is released, the valve re-seats and provides a tight seal.
The optimized fluid dynamic design of the valve body and valve pallet is a result of many years of research, resulting in stable operation of the valve pallet, optimized performance, and reduced product losses.
