Electrical controlled valves are necessary in order to remote-control machines from the [[GVCS]]. However, the solenoid valves for the power level of interest cost about $200 per double-acting channel - see [[CEB Press v16.09]]. There is thus a strong case for open source solenoid valves, which we could produce for probably 1/5 of that cost.

			=Development Strategy=
			Based on the success with the double clamp design of clamp blocks in the [[3D Printer Design Evolution]] - and specifically [[3D_Printer_Log#Wed_Aug_17.2C_2016]] - we can add metal plates to the flat faces of 3D prints. Further, we can print thermoplastic elastomer planar or o-ring seals. ABS is 6000 PSI strong. Combined with 50 ksi metal plates, we should be able to achieve open source 3D printed solenoid valves for hydraulic applications at 2000 PSI. If not, then the least would be lower pressure applications. For the higher pressure applications, it may be necessary to do metal casting, such as lost PLA casting.

	~~#redirect~~ [[~~Electronic Valve Engine~~]]		Electrical controlled valves are necessary in order to remote-control machines from the [[GVCS]]. However, the solenoid valves for the power level of interest cost about $300 per double-acting channel. There is thus A strong case for open source solenoid valves, which we could produce for probably 1/5 of that cost.

			==Requirements==
			30 gallon per min (~115 l/min) hydraulic flow at 3000 psi (~200 bar) pressure.

			==How does it usually work==
			All solenoid valves I saw till now work similar.

			{{YoutubePopup\|eKqfP2F_Pl0}}

			I spool is centered inside of the body with springs. On both sides of the body are electromagnets that can push a shaft that presses the spool towards the other side. Therefore you can realize three different states of operation.

			==Ideas for simplification==
			As I see it the most difficult part to produce is the body as there are very complex geometries inside that can only be formed by casting or 3D-printing.
			For that reason I concentrated on simplifying the geometry of the body.

			==Possible solutions==
			[[File:Solenoid_Valve_01.jpg\|thumb\|alt=Alt text\|Body with spool 01]]

			The body is a simple metal block with only ordinary drill-holes and threads, easy and cheap to manufacture. The outputs 1 and 2, and 3 and 4 have to be connected width hoses to allow double-acting. Connecting them outside of the block with possibly quite cheap hoses might make the whole thing cheaper than produce the complex forms necessary to work otherwise.

			==Possible issues==
			*The form of spool shown above will most probably form turbulences that might be a problem.
			*All surfaces have to be very accurately to enable leak tightness.
