Safety Warning

Item Information

Parker counterbalance valves series ZNS in sandwich design control the actuator movement at overrunning loads via a leak-free poppet valve. Thereby they enable a reliable operation and a linear lowering speed of the cylinder.

The return flow from the actuator is piloted and controlled by the inlet flow to the actuator, ensuring a cavitation-free lowering of the load. The counter balance valve operates as a pressure relief valve. The setting pressure is lowered by the pressure in the inlet line.

Markets:
• Industrial
• Machine tools

Features/Benefits:
• Compact, proven design that represents our long-term experience in hydraulics
• Controlled movement loads - prevents cavitation
• Load holding via leak-free poppet valve - ensures reliable operation
• Short delivery time - no warehousing necessary
• Available in two sizes:
    - ZNS*01 – NG06 (CETOP 03)
    - ZNS*02 – NG10 (CETOP 05)
• Secondary relief protection for the actuator

Applications:
• Suitable for general hydraulic applications
• Machine tools

Please note:
To ensure safe load holding the setting pressure should be approximately 30 % higher than the max. load pressure.
