Venn VD-1H type vacuum adjustment valve
Manufacturer: Venn Co., Ltd.
Model: VD-1H
Features
- When the negative pressure drops below the set value, the valve opens.
- As a result, it draws in air and prevents piping and equipment from becoming vacuumed.
- In addition, when installed on a steam pipe with a silencer, it prevents water from being drawn in after the steam stops.
