Suggested Merger
[edit]I have suggested a merger with Hydraulic cylinder but it might be better to add a section on "technology of fluid power" to the Fluid power article. Biscuittin (talk) 19:21, 18 August 2010 (UTC)
- FWIW, I would rather see a separate article on hydraulic valves. Yes, many of the makers of cylinders make valves also. Yes, valves and cylinders are both required to make circuits. BUT the issues associated with controlling the flow of fluid (and controlling the control in the case of electric over hydraulic, or pneumatic over) are particular to the valve problem. — Preceding unsigned comment added by 173.76.32.188 (talk) 11:36, 13 May 2011 (UTC)
- I have to agree with the comment posted on 13 May 2011 suggesting that the two articles stay separate. Engineering a servo valve and engineering a hydraulic piston are two very different problems. And they don't always have to go together. 69.174.58.156 (talk) 18:24, 7 January 2013 (UTC)
High cost of Electrohydraulic servo valves?
[edit]I am doing some research to build my own semi-professional human-sized robot as a hobby project, and I am discovering that EHSV's are typically ridiculously expensive and far outside the range of noncommercial robot builders to afford.
Apparently the cost for a single EHSV is well over US$250 each (good luck nailing down specifics as most manufacturers will only "quote" prices), and they are more commonly used in manufacturing factories, or in industrial or military motion control applications. The high cost makes them unsuitable for amateur robot motion control unless the number of driven actuators is extremely limited.
It seems like this is information worth including in the article, as it may benefit others seeking to use EHSV's for precise motion control in their robot design projects, though I don't yet know if this can be cited. -- DMahalko (talk) 00:33, 19 February 2015 (UTC)
