Vickers 2W NC Valve/SV3 12 C A12T 24DG

For refuse hauler applications, the pressure rating on this valve is solid. It handles up to 350 bar, which works out to 5000 psi, and flow goes up to 114 litres per minute. The body is hardened and ground steel, so it holds up in heavy-use environments where wear is a real concern. It's a 2-way, 2-position normally closed design, meaning the valve stays shut until the solenoid energizes it, which is generally what you want for that kind of application.
