Abstract: A vapor control valve (12) and system therefor for controlling fuel tank (14) pressure and for purging hydrocarbons from a storage canister (16) comprising a single electrical coil (44) responsive to control signals, wound about a carrier or bobbin (34) including a central passage (36) and means for dividing said central passage into first (40) and second (42) axially aligned portions; a first piston (60) slidably received within said central passage at said first portion (40); a second piston (80) slidably received within said central passage at said first portion (42); a first valve seat (132) for receiving said first piston; a second valve seat (106) for receiving said second piston, a first spring (66) for biasing said first piston into said first valve seat; a second spring (90) for biasing said second piston into said second valve seat, wherein the spring constant of said first spring is less than the spring constant of said second spring.
