Do not use these roducts where ressures and temeratures can exceed those listed in Technical Data. Please consider the corresonding catalogue sheets. Before using these roducts with fluids other than those secified, for non-industrial alications, life-suort systems, or other alications not within ublished secification, lease consult NORGREN. Through misuse, age, or malfunction, comonents used in fluid ower systems can fall in various modes. The system designers are warned to consider the failure modes of all comonent arts used in fluid systems and to rovide adequate safeguards to revent ersonal injury or damage of equiment in the event of such failure. System designers have to rovide a warning to end users in the system instructional manual, if rotection against a failure mode cannot be adequately rovided. System designers and end users are cautioned to review warnings found in instruction sheet as acked and shied with these roducts. N/UK
