In cases where flange connections are required, this valve offers the same technical features as the 630 version of the overflow valve. The robust all-metal design makes these overflow valves ideal for harsh operating and environmental conditions when sensitive control is required. The set pressure can easily be read off the (optional) pressure gauge.

The valve is used to protect pumps in closed circuits against overloading as well as for control purposes in pressure systems for air, neutral/non-neutral gases and technical vapours.
