Bieri Hydraulic Proportional Valves
Bieri PDV700 Proportional Pressure Relief Valve
Bieri's proportional valves offer pressure ranges of 400, 550 and 700 bar, controls pressure within precise limits. Available in direct-operated for low flow and pilot-operated for high flow applications. Works well for controlled decompression of large oil volumes as found in presses
and accumulators.
