Future Belongs to Smart Valves
This issue is the driving force behind the development of smart valves – the biggest prospect in manufacturing control valves and shutoff valves, required by the modern automatic process control systems. The use of smart valves (i.e. the use of valves with a wide range of electronic control and diagnostics functions) will ensure extensive... »
PF5 and PF6 series of piston actuated valves
Piston actuated valves. Spirax Sarco’s PF5 and PF6 series of piston actuated valves provide a competitive solution for on/off control in a wide range of industrial applications. The robust and compact valves provide tight shut-off by utilising a PTFE plug seal, while the valve stem sealing is achieved through self-aligning PTFE chevrons to maximise sealing... »

HAWE Hydraulik SE, Munich, has developed additional versions of its intermediate plate, type NZP, with the hole pattern NG 6, thereby pursuing its strategy of offering components with tried and tested HAWE technology and hole patterns that conform with industry standards. Newly added are versions for pressure control valves of the types CDK and CLK.... »
Proportional High Flow Pressure Control Valve Offers High Flow
Diversified industrial manufacturer Eaton Corporation today announced the introduction of a new high-flow, proportional pressure relief valve with integrated control electronics. It is a genuine ‘plug-and-play’ unit with industry standard 7-pin connector hook-up. The new valve designated KBCG5-3, complements Eaton’s known KB proportional valve series by extending flow capability up 40 litre/ min whilst offering... »
FISHER HANDBOOK Valve Type And Characterization Sizing
in this chapter can have a dramatic impact on the economic results of an operating plant. More and more control valve users focus on dynamic performance parameters such as dead band, response times, and installed gain (under actual process load conditions) as a means to improve processloop performance. Although it is possible to measure... »
Control Valve Performance FISHER HANDBOOK
In today’s dynamic business environment, manufacturers are under extreme economic pressures. Market globalization is resulting in intense pressures to reduce manufacturing costs to compete with lower wages and raw material costs of emerging countries. Competition exists between international companies to provide the highest quality products and to maximize plant throughputs with fewer resources, although... »

Mechanical Seal Installation Check
Face the facts, seals fail. They do not wear out. Most often something comes along to disturb the smooth running of the pump and BLAM you are facing a steady leak which has already destroyed your seal by damaging the seal faces. But there is another case. The seal that leaks on startup after... »

Butterfly valves From FISHER HANDBOOK
For butterfly valves where the seat is mounted in the valve body, four basic types of seat exist: 1. Boot seats are the traditional seat style. This type of seat is a separate component which typically has a “U” shaped cross section and completely lines the ID of the valve body. They are retained in... »
Butterfly valves
Within the quarter turn family of valves, ball valves are dominant in the sub-2 inch size category. Above 2 inches in size, butterfly valves become much more prevalent primarily for economic reasons. Butterfly valves exhibit a number of characteristics which make them especially well suited to use in general service type applications. Those characteristics include:... »
Butterfly valves in control valves applications
Butterfly valves are commonly used as control valves in applications where the pressure drops required of the valves are relatively low. Butterfly valves can be used in applications as either shutoff valves (on/off service) or as throttling valves (for flow or pressure control). As shutoff valves, butterfly valves offer excellent performance within the range... »
