Design Features

• Cylindrical 3-channel automatic exhaust valve
• Ventilation outlet of the same nominal size (large opening cross section corresponding to flange size)
• Flange connection size according to EN1092-2 (DN50 with threaded connection option)
• High efficiency and high performance exhaust valve to protect the pipeline from damage caused by vacuum
• High-speed exhaust prevents premature closure of the valve, ensuring optimum gas effect in the process of filling the pipe or vessel
• Two-stage exhaust system provides effective protection. When the high-speed exhaust is exhausted, the small-port exhaust can effectively prevent vibration.
• Under normal working conditions, the air inlet can continuously and reliably inhale
• Compact structure, small size and light weight
• Safe and reliable, advanced technology
