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 harsh operating- and environmental conditions, when sensitive control is required.
The set pressure can easily be read-off the (optional) pressure gauge.
