The new range of three-port QL valves, manufactured by industrial process control company Spirax Sarco provides a wide range of applications for the control of water, oils and other industrial fluids used in controlling energy and fluid flows for manufacturing and other processes, reports the company.
The electrically actuated control valve options cover from PN25 up to PN40 pressure ratings, with materials in spheroidal graphite iron or cast steel up to 250 ºC.
Spirax Sarco reports that its valve body and electric actuator combinations provide reliable and competitive solutions to most fluid control problems.
The wide range of options provides one source to meet most plant standards and the enclosure of electronic components minimises maintenance problems in dirty environments.
There is provision for optional switches and potentiometers for control and management information feedback.
A plug-in positioner, for easy conversion, reduces spares stocking costs and the long-life valve components simplify and reduce maintenance requirements, as do the constant force stem seals that provide added control, accuracy and reduced valve maintenance, reports the company.
The user benefits of the three-port valve include constant force stem seals for added control, accuracy and reduced valve maintenance.
Other benefits of the control valve are its long-life valve components, which simplify and reduce maintenance requirements.
The plug-in positioner enables simplified conversion and reduced spares stocking costs, as well as provision for optional switches and potentiometers for control and management information feedback.
The enclosure of electronic components reduces maintenance problems in dirty environments, and the wide range of options provides one source to meet most plant standards, reports Spirax Sarco.
