Benefits

• Adjustment range 4 to 200 bar for circuits in the 200 bar class
• Discharge flow up to 400 l/min at 350 bar permitted operating pressure
• Poppet seat design with low leakage when closed
• Internal hexagon with protective cap secures the set value

• 5.9 kg weight, NBR seals, connection diagram ISO 6264-08-13

Application

Machine tools, clamping hydraulics and conveying equipment often run at 200 bar nominal pressure. A matching limit avoids oversizing the safety stage. Through the subplate interface a change to another pressure step of the range stays possible at any time.
