mikec Posted August 20, 2014 Share Posted August 20, 2014 Hi guys asked this question on another forum but got a limited response so thought I'd ask here to. Would a cetop 5 solenoid valve be ok to run a mike marker using a pto pump? Or is it a bit excessive? Cheers mike Quote Link to comment Share on other sites More sharing options...
aniesigh Posted August 20, 2014 Share Posted August 20, 2014 Been wondering this myself. Figured that it's bête to go bigger knowing it's not limiting the system even slightly. When there's lots of fluid flowing, if it is restricting it then it will be heating the fluid and slowing the winch so a double neg. Still not sure it's not overkill though. My setup has 2 pumps so in a high speed low pressure scenario it'll be flowing a fair bit Quote Link to comment Share on other sites More sharing options...
Anderzander Posted August 20, 2014 Share Posted August 20, 2014 Excuse my ignorance - but are the Type R solenoids Cetop ? Quote Link to comment Share on other sites More sharing options...
nickwilliams Posted August 20, 2014 Share Posted August 20, 2014 In answer to the OP, CETOP 5 is a bit overkill, but it won't do any harm (other than weigh you down a bit!) In answer to Anderzander, I'm not sure what you mean by a 'type R' solenoid but CETOP is a standard for the port dimensions and layout for hydraulic valves and so far as I am aware there is no standardisation between solenoids.

Anderzander Posted August 20, 2014 Share Posted August 20, 2014 Thanks Nick. I was referring to the milemarker winch set up that firstfour sell - which uses this solenoid: http://m.firstfour.co.uk/item/2129361/hydraulic-control-valve-12vdc Quote Link to comment Share on other sites More sharing options...
nickwilliams Posted August 20, 2014 Share Posted August 20, 2014 The pictures on that site don't look like CETOP valves to me, although they may be CETOP valves with a sub-plate to provide the interface to the incoming/outgoing hydraulic pipework.

mikec Posted August 20, 2014 Author Share Posted August 20, 2014 Is a cetop 5 physically a big unit then? Never seen one in the flesh Quote Link to comment Share on other sites More sharing options...
nickwilliams Posted August 20, 2014 Share Posted August 20, 2014 Not really. Typical dimensions here:http://www.hasmak.com.tr/parkervalf/Parker%20NFPA%20D05,%20CETOP%205%20Directional%20Control%20Valves.pdfFor comparison, CETOP 3 is probably a more normal size for winches etc: http://www.hasmak.com.tr/parkervalf/Parker%20NFPA%20D03,%20CETOP%203%20Directional%20Control%20Valves.pdf So, a typical CETOP 3 12V 3 position valve is 244 mm overall length where as a CETOP 5 one is 299 Quote Link to comment Share on other sites More sharing options...
mikec Posted August 20, 2014 Author Share Posted August 20, 2014 Ok cheers nick, it's just I've found a twin spool cetop 5 for a decent price and I've been looking for ages to find 12v one. Might as well chance it and hope it's all ok Quote Link to comment Share on other sites More sharing options...
nickwilliams Posted August 20, 2014 Share Posted August 20, 2014 Make sure it has the correct port configuration - you will need open which has an open centre position (i.e. routes the pressure (P) line back to tank (T)) unless you are going to do clever things with additional valves.

Could you have a look on the valve please nick just to see if it is I can never make sense of those diagrams thanks Quote Link to comment Share on other sites More sharing options...
nickwilliams Posted August 20, 2014 Share Posted August 20, 2014 Yes, that's the kiddie. The critical bit is the line which goes between the 'P' and the 'T' in the middle diagram (between the two lower mounting holes). Quote Link to comment Share on other sites More sharing options...
Wingnut Posted August 21, 2014 Share Posted August 21, 2014 ".........I've been looking for ages to find 12v one." Dosen't it say 24v on the valves ? Peter. Quote Link to comment Share on other sites More sharing options...

Mmmm valve came today and I see what you mean about the weight!!!! ".........I've been looking for ages to find 12v one." Dosen't it say 24v on the valves ? Peter. Yeah but he had 12v in to So all in all I'm not sure now where it could go, as it sure as hell ain't fitting under the wing top lol. Thinking of mounting near the tank in the back and just running motor hoses to the front Quote Link to comment Share on other sites More sharing options...
steve b Posted August 29, 2014 Share Posted August 29, 2014 ..no space under the bonnet? The coil is removable so you could swap for 12v easily , remove the nut on the end of the coil and slide it off. With 12v going into a 24v coil you may find it's not fully opening.... cheers Steveb Quote Link to comment Share on other sites More sharing options...
mikec Posted August 29, 2014 Author Share Posted August 29, 2014 Sorry misunderstanding there this one is 12v, not really room under the bonnet it's roughly 12"x7"x8" in size! Quote Link to comment Share on other sites More sharing options...
steve b Posted August 29, 2014 Share Posted August 29, 2014 Ah ok , in the back sounds like the place for it . Are you putting a lockout/overcentre valve on the winch motor? ....if you want a MM for the back I have a couple of spare ones MM on a pto pump will pull at a good speed and load in 5th . With the std motor you probably don't want to be ay higher than 180bar on your prv . cheers Steveb Quote Link to comment Share on other sites More sharing options...
mikec Posted August 29, 2014 Author Share Posted August 29, 2014 Had thought about the over centre valve but may do without for a bit depending how much etc. I don't have a prv yet I'm hoping I can fit one to the manifold somehow. How much are you selling your other mm for? Quote Link to comment Share on other sites More sharing options...
steve b Posted August 29, 2014 Share Posted August 29, 2014 just looked at the pics again , and yeah no prv , that's an expensive 12v spool with no prv . Iirc the last prv block I bought was about £50 , so not too expensive . will pm to talk about MM's cheers Steveb Quote Link to comment Share on other sites More sharing options...
Team Idris Posted August 29, 2014 Share Posted August 29, 2014 Over-run valve is supposed to be important, so the winch doesn't runaway once cavitated. I haven't run without one to find out Quote Link to comment Share on other sites More sharing options...
mikec Posted August 29, 2014 Author Share Posted August 29, 2014 I'll probably take the chance without one to be honest and see how I go it's not used as a comp motor cheers mike Quote Link to comment Share on other sites More sharing options...
steve b Posted August 29, 2014 Share Posted August 29, 2014 the o/c valve is effectively the brake as it locks the flow in and out of the ports on the motor based on pressure differential between load and return lines if I understand it correctly . My rear MM has no o/c valve and does stop under winch out under load using just the spool but does creep a bit cheers Steveb Quote Link to comment Share on other sites More sharing options...

Or is it oressure that matters here? Quote Link to comment Share on other sites More sharing options...
steve b Posted August 29, 2014 Share Posted August 29, 2014 it's more about having the hyd lock as close to , or preferred bolted directly to the device you need to lock I think , and it's opened when the delivery pressure exceeds the pressure on the locked side of the circuit cheers Steveb Quote Link to comment Share on other sites More sharing options...
aniesigh Posted August 29, 2014 Share Posted August 29, 2014 Also if you were winching up a bank or something and a hose split, with no OCV there's only one direction you're going! 1 Quote Link to comment Share on other sites More sharing options...
