一般描述
The simplest way to maintain vacuum control is through this cost-effective needle valve. Air is drawn in through a fine regulation valve and the resulting vacuum is set. A manometer displays the pressure. A Woulff bottle is recommended with this valve so that it can be a buffer vessel and condensate trap.
