631 Overflow and pressure control valves made of gunmetal, straightway form, with flange connections
In cases where flange connections are required, this valve offers the same features as the 630 version.
The robust all-metal design makes this valve ideal for heavy-duty operational and environmental conditions when sensitive control is required. The set pressure is easy to read on the (optional) pressure gauge.
For the protection of:
- Pumps against overload in closed circuits for neutral/non-neutral and non-adhesive liquids
For the control of:
- Systems under pressure for air, neutral/non-neutral gases, and vapors
- Industrial installations
- Power plant technology
- Pump stations
- Machine engineering
