A modulator valve assembly ( 10 ) includes a valve seat ( 32 ) assembled as part of a housing ( 12 ), and the valve seat ( 32 ) defines inlet and outlet ports to allow fluid to flow between an inlet passage ( 28 ) and an outlet passage ( 30 ) along a fluid flow path. The modulator valve assembly ( 10 ) also includes a movable valve member ( 62 ) that is threaded to a rod ( 56 ) that extends through the valve seat ( 32 ), and as the rod ( 56 ) rotates, the movable valve member ( 62 ) moves axially along the rod ( 56 ). A pin ( 72 ) extends from the housing ( 12 ) to engage the movable valve member ( 62 ) to prevent the movable valve member ( 62 ) from rotating with the rod ( 56 ). The movable valve member ( 62 ) slides along the rod ( 56 ) into the fluid flow path and blocks the fluid from entering the housing ( 12 ).
