Safety Warning

Full Product Description

Parker's direct operated pressure relief valve series EVSA is a flow compensated seated type valve for screw-in mounting and particularly suitable for the pressure relieving of hydraulic systems. Even at high flow rates the preset pressure remains virtually constant. It is available in two sizes (NG06 and NG10) and three pressure stages.

Markets:
• Industrial
• Machine tools

Features/Benefits:
• Robust valve design - minimized failure
• Almost constant pressure level even at high flow rates - improved process and product accuracy
• Short delivery time for most versions - no warehousing necessary
• 3 pressure stages - makes selection and adaption easy
• 2 adjustment modes:
    - screw with hexagon socket
    - cylinder lock

Applications:
• Suitable for general hydraulic applications
• Machine tools

Function:
When the pressure in port P exceeds the setting pressure the cone opens to port T and thus limits the pressure in port P to the adjusted level. The integrated damping spool prevents pressure fluctuations in the transition region. The pressure is set by the adjusting screw, which is locked by the clamping screw. The setting can optionally be secured by a cylinder lock.

Please note:
The spring must be unloaded when the EVSA is screwed out of the manifold.
