NIPPON GEAR CO.,LTD - Products Guide:Valve Actuators/Limitorque

Used Actuators

Under license from Flowserve Limitorque USA who has more than 70 years of history and field experiences in valve actuators, Nippon Gear has been manufacturing actuators in Japan with high appraisal and deep reliance. We have adopted a torque motor having a large starting torque and small inertia, which is optimum for valve opening and closing operation, a faultless limit switches with wide applicability. These valve actuators find applications in a wide range of industrial environments, from petroleum, nuclear, and generating plants to water/sewer pipelines advanced. Further, we are undertaking improvement development of actuators with our own new technologies.

The applications for linear motors and linear actuators overlap, so maybe you can use a linear actuator
The latest issue of the catalog from American Science and Surplus, also found at , has a few linear actuators, but they are 12 volt, and cheap.
Similar, more expensive, units are found at the surplus giant Herbach and Rademan who have an online catalog
Personally, I would order by mail, rather than drive anywhere in S.F.
good luck

Your grid tie inverter

2006-11-07 17:40:58 by solarmandotorg

From what i gathered from google, your inverter probably does use MPPT (maximum power point tracking).. read your manual and make sure though.
like i said, seasonal tilt makes a huge difference. you have about 3 times the panels i do. i leave mine in place but i can move them in about 10 minutes and that includes dragging the ladder out.
you could even set up some linear actuators to move them up and down. these are the things that swung the huge satellite dishes back in the 70' and 80s.. little moter with a long bolt that spins a nut up and down a pipe.. a tiny motor can really move something like that
