1. A pulsator, comprising: a first valve chamber;a first electrically powered coil at least partially surrounding the first valve chamber and operable to generate a first magnetic flux;a first magnetic pole piece arranged in the valve chamber and having a metal surface;a first armature arranged in the valve chamber and having a first end nearest the magnetic pole piece and a second end, wherein the first end of the first armature has a metal surface and the second end has a first sealing surface and a second sealing surface, wherein the first sealing surface of the first armature is a separate component from the second sealing surface of the first armature;a first input port configured to admit atmospheric air to the first valve chamber;a second valve chamber;a second electrically powered coil at least partially surrounding the second valve chamber and operable to generate a second magnetic flux;a second magnetic pole piece arranged in the second valve chamber and having a metal surface;a second armature arranged in the second valve chamber and having a first end nearest the second magnetic pole piece and a second end, wherein the first end of the second armature has a metal surface and the second end has a first sealing surface and a second sealing surface;a second input port configured to admit atmospheric air to the second valve chamber; anda third input port coupled to a vacuum line. 2. The pulsator of claim 1, further comprising: a first input port admitting atmospheric air;a second input port coupled to a vacuum line;a first air chamber at one end of the first valve chamber and operable to receive vacuum pressure from the third input port in a first mode of operation and operable to receive atmospheric air pressure from the first input port in a second mode of operation; anda first output port coupled to the first air chamber and operable to output atmospheric air pressure or vacuum pressure based on the mode of operation. 3. The pulsator of claim 2, wherein: in the first mode of operation, the first coil activates to generate a first magnetic flux which causes the first armature to move into a first position in the first valve chamber in response to a magnetic attraction between the metal surface of the first pole piece and the metal surface of the first armature, wherein the first sealing surface of the first armature creates a seal in the first air chamber to block the atmospheric air admitted by the first input port; andin a second mode of operation, the first coil deactivates such that the first armature moves into a second position in the first valve chamber, wherein the second sealing surface of the first armature creates a seal in the first air chamber to block the vacuum pressure from the third input port. 4. The pulsator of claim 3, wherein the first sealing surface of the first armature creates the seal with a chamfered surface of the first air chamber in the first mode of operation. 5. The pulsator of claim 2, further comprising: a base structure that includes the third input port and the first output port; anda cover structure that includes the first input port. 6. The pulsator of claim 5, wherein the first output port is arranged at an approximately forty-five degree angle to the base. 7. The pulsator of claim 6, wherein: the base structure comprises a base lip along a perimeter of the base structure; andthe cover structure comprises a cover lip along a perimeter of the cover structure, the cover lip mating with the base lip by overhanging and partially extending around the cover lip. 8. The pulsator of claim 2, wherein the third input port comprises a first mating feature and the base structure comprises a second mating feature, wherein the first and second mating feature are shaped such that the orientation of the first mating feature is locked with respect to the second mating feature. 9. The pulsator of claim 1, wherein the first sealing surface of the first armature comprises a rubber o-ring encircling the first armature. 10. The pulsator of claim 1, wherein the second sealing surface of the first armature comprises a rubber cap positioned at the second end of the first armature. 11. The pulsator of claim 1, further comprising: a second air chamber at one end of the second valve chamber and operable to receive vacuum pressure from the third input port in a first mode of operation of the second valve chamber and operable to receive atmospheric air pressure from the second input port in a second mode of operation of the second valve chamber; anda second output port coupled to the second air chamber and operable to output atmospheric air pressure or vacuum pressure based on the mode of operation of the second valve chamber. 12. The pulsator of claim 11, wherein: in the first mode of operation of the second valve chamber, the second coil activates to generate a second magnetic flux which causes the second armature to move into a first position in the second valve chamber in response to a magnetic attraction between the metal surface of the second pole piece and the metal surface of the second armature, wherein the first sealing surface of the second armature creates a seal in the second air chamber to block the atmospheric air admitted by the second input port; andin a second mode of operation of the second valve chamber, the second coil deactivates such that the second armature moves into a second position in the second valve chamber, wherein the second sealing surface of the second armature creates a seal in the second air chamber to block the vacuum pressure from the third input port. 13. The pulsator of claim 11, wherein the first valve chamber and the second valve chamber operate independently and generally alternately with each other with some overlap in operation. 14. The pulsator of claim 1, wherein the first valve chamber and the second valve chamber reside in a common housing that includes a base structure and a cover structure. 15. The pulsator of claim 14, further comprising a single nut and bolt assembly arranged between the first valve chamber and the second valve chamber and that couples the base structure and the cover structure. 16. The pulsator of claim 1, further comprising an air baffle to at least partially separate the first air chamber from the second air chamber. 17. A pulsator, comprising: a valve chamber;an electrically powered coil at least partially surrounding the valve chamber and operable to generate a magnetic flux;a magnetic pole piece arranged in the valve chamber and having a metal surface; andan armature arranged in the valve chamber and having a first end nearest the magnetic pole piece and a second end, wherein the first end of the armature has a metal surface and the second end has a first sealing surface and a second sealing surface, wherein the first sealing surface of the armature is a separate component from the second sealing surface of the armature;wherein: in a first mode of operation, the coil activates to generate a magnetic flux which causes the armature to move into a first position in the valve chamber in response to a magnetic attraction between the metal surface of the pole piece and the metal surface of the armature, wherein the first sealing surface of the armature creates a seal; andin a second mode of operation, the coil deactivates such that the armature moves into a second position in the valve chamber, wherein the second sealing surface of the armature creates a seal. 18. The pulsator of claim 17, further comprising: a first input port admitting atmospheric air;a second input port coupled to a vacuum line;an air chamber at one end of the valve chamber and operable to receive vacuum pressure from the second input port in the first mode of operation and operable to receive atmospheric air pressure from the first input port in the second mode of operation; andan output port coupled to the air chamber and operable to output atmospheric air pressure or vacuum pressure based on the mode of operation.
