I just finished testing the new clippard solenoid .I is part #mme 2pds wo12.It works well on 6 volts even better o 7.2. It has the same flow rate as a mav 2 weights much less than a kip and costs 19.95. I am switchin to this valve on al my ships. I forgot it is rated for 180 psi.
I went on their site, and did not find that part # you listed, can you give a link also for it? Never mind I had to add the dashes into the part number. That part # you listed is for 12 volts, how well does it work when its got 150 psi on it, does it open when the 6 volts is applied.
The guys around me have been running/switching to these, I have them installed in the new VDT and they worked fine when I tested them on 6V and 7.2V but I dont think I had pressure on them since I was out of gas. I'll try and remember to hook them up and test them tonight since I just got a new tank. I was going to get a chance to battle test them this weekend but that will have to wait for a few weeks, still some of the guys around here will still be using them so they will probably still get battle tested, I'll try and get results from that when I get back to town at the end of next week. Only thing about them so far that is really different is that the ports are 1/8" npt, you need a reducer on the out side but for the in port I just soldered a 1/8"npt fitting to my expansion tanks and screwed them directly into the solenoid. Again I'll try and get some pics when i get home this evening.
I'm going to these on the Richelieu ... ordered them yesterday. I have one right now for testing purposes, but it hasn't had gas in it to see if 6v is enough to actuate it. It does work on 6v, just don't know yet if it'll do it with pressure. There is another valve by Clippard that may show promise. Found by the guys up in the Dayton area, it is the MME-31NES-W012. It's a 3-way valve, so you would have to put a muffler on the exhaust port. The nice thing about this valve is it's 27cfm flow rate ... way more than the KIP. The Clippard catalog gives a maxinum usable pressure as 120 psi, but thier web site says it will handle 180 psi. It comes in 10-32 ports, and runs around $25 each. Kudos to the guys that found it.
Here are the pics as promised. They worked with both 6V and 7.2V under pressure. I cant give them the battle tested seal of approval yet but so far everything looks good.
Well thats nice, $20 is alot better than $50+ now for a Kips. [] Mike when I tried those high flow pressure actuated poppets, they spurted, and were uncontrollable, as soon as I tighted the barrel down. That one you listed will do about 40 cfm at 150 psi. Let me know how it works.
These are what I use on the NJ... Never trusted them w/o a watertight box. I see you in your ship, however, they're naked, how are they holding up?
I don't think that ship's been in the water for combat... no drive gears But I'd be interested to hear how it goes!
Right on Tug. Actually you cant see it from that view but it doesnt have sides yet either, thats the last big thing I have to do before I start taking her out on the water and doing some testing. I dont see why you would need to waterproof the solenoids they look just as sealed up as the KIPs and Ive never had a problem with them getting wet. If it turns out to be a big deal i'll just coat all the "seams" with scotchkote. Since the coils are already encapsualted you really only have the valve body, piston, and spring to worry about. The body is AL and Plastic so im not to concerned there, the piston and spring appear to be stainless steel but thats just I remeber from looking at them, if you think its an issue I could always get a magnet out and test them this evening. What prompted you to put them in a watertight box?, why dont you trust them outside of one?
The 3-way valve is a spool type valve vs the poppet type KIP and the Clippard 2-way valves. I'm curious if the spool valve would work fast and positive enough for our cannon systems. I won't be able to buy and test the 3-way until probably next month. There is just too much going on at work and during the weekends in April to spent time checking it out.
