The National Fluid Power Association (NFPA) published a new ISO
standard --ISO 5781:2000--that addresses the interchangeability of valves in
hydraulic systems. Valves covered in the new standard include pressure-reducing
valves, sequence valves, unloading valves, throttle valves, and check valves.
The standard applies to valves used in industrial equipment such
as machine tools and packaging equipment. It specifies dimensions and other
characteristics of the surfaces on which the valves are mounted.
NFPA is making the documents available for $43 for NFPA members.

Design collaboration now includes the entire value chain. From suppliers to customers, purchasing to outside experts, the collaborative design team includes internal and external groups. The design process now stretches across the globe in multiple software formats.
A new high-pressure injection-molding technology produces near-net shape parts with 2-inch-thick walls from high-performance materials like PEEK, PAI, and carbon-filled polymers. Parts show no voids, sinks, or porosity, have more consistent mechanical properties, and are stronger.
