Druck IO-VAC-SYS - Vacuum System Check Valve Kit
The GE Druck Vacuum System Check Valve Kit allows exhaust pressure to bypass the vacuum pump to atmosphere, which improves control performance from any positive pressure downwards.
When pressure from a volume that is connected to PACE is venting, the gas flows through the negative source port. High pressure can overload a vacuum pump, the vacuum system check valve kit allows pressure to by-pass the vacuum pump and vent to atmosphere.
