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 device to relieve vacuum in tanks, containers, and process engineering equipment. It prevents the in-breathing of air until reaching the set pressure. The valve is a perfect solution for corrosive, polymerizing, or sticky substances.
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.
Due to our highly developed manufacturing technology, the tank pressure is maintained up to the set pressure with a seal 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 a stable operation of the valve pallet, optimized performance, and reduced product losses.
