This valve holds system pressure at the set value while discharging flows of up to 2000 l/min. The adjustment range runs from 3.9 to 315 bar and maximum operating pressure is 315 bar. The design is pilot-operated with a poppet seat.

Benefits

• Up to 2000 l/min flow, laid out for large power units
• Adjustment range 3.9 to 315 bar at a maximum operating pressure of 315 bar
• Size 52 with flange connection and three ports
• Internal hexagon with protective cap for the pressure setting
• 27.18 kg weight, NBR seals for HL hydraulic fluid

Application

It is used for pump protection and bypass circuits with very high throughput. Because the valve is pilot-operated, the pressure difference stays flat across the whole flow range. The seat design limits leakage in the closed state.
