In a vacuum system, this type of vacuum control is accomplished by installing a throttle valve which works by throttling the pressure between the vacuum pump and the process in order to control the vacuum level. Sometimes, the use of a throttle valve is referred to as downstream control. This type of control helps extend the life of your vacuum pump.
When using a throttling valve to regulate the vacuum level, the valve is a restriction between the two pieces of equipment. It creates a pressure drop between the two, thereby allowing the process to operate at a set pressure while another area’s pressure varies based on loading. Valve selection is critical if this type of control is to be practical. This type of vacuum control can be used over a wide range of vacuum pressure.
