A double solenoid valve especially for anti-lock braking (ABS) applications has a normally open conduit for connection to a first port fluidically in series with a normally closed conduit between second and third ports. A slow two-way path continuously connects the second port. The double valve when used in ABS can handle incipient locking, actual locking, quick releasing to normal after emergency anti-lock action, and purge modes.

A valve assembly for use in a vehicle anti-lock braking system (ABS) comprising: (a) a valve body having aligned portions of differing cross-sections adapted for connecting in a multi-ported common recess in a receptacle and having, (i) a first cross-section having an inlet port formed therein in a direction transverse to the direction of insertion into said recess, (ii) a second cross-section having a dump port provided therein in a direction transverse to the direction of insertion into said recess, said dump port being spaced from said inlet port, (iii) a sigal or service port disposed in said portions in a direction common with said direction of insertion; (b) means defining a fluid pressure tight valving chamber; (c) a first normally open electrically actuated valve means disposed for controlling flow between said inlet port and said valving chamber and operative upon electrical actuation to isolate said chamber from said inlet port; (d) a second normally closed electrically actuated valve means disposed for controlling flow between said valving chamber and said dump port and operative upon electrical actuation to enable fluid flow from said chamber to said dump port; and, (e) means defining a continuously open passage between said valving chamber and said service port.
