Industrial control valves are <i>very</i> expensive so I opted for hardware store components, but I have a leak so perhaps need to look at other options.salsahttps://www.blogger.com/profile/03691727863273668045noreply@blogger.comtag:blogger.com,1999:blog-4029477663972602198.post-59252575971096202892009-07-22T00:09:19.118-07:002009-07-22T00:09:19.118-07:00More complex control systems using valves requirin...More complex control systems using valves requiring automatic control based on an external input require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.industrial equipmenthttp://www.meaincorporated.com/noreply@blogger.com
