ABSTRACT:
There is provided a low profile valve assembly for controlling flow of air and the like. The valve assembly includes a housing defining inlet and outlet ports and a valve operator located within the housing. The operator includes a body portion seated in the housing with an axis of rotation and defining an internal passage with inlet and outlet ends. An actuator rotates the body portion a first predetermined distance to a fill position to allow flow through the internal passage and a second predetermined distance opposite the first direction to a vent position to allow flow to vent from the valve assembly through the outlet end. A spring extends from the valve operator adjacent the body portion between the axis of rotation and the valve housing. The spring extends partially about the axis of rotation to bias the body portion to an off position to substantially prohibit flow through the valve operator when the body portion is not being actuated to the fill and vent positions. The spring operates substantially within an internal space in the operator about the axis of rotation. The valve assembly includes an orifice to reduce volume flow through the valve assembly and an exhaust passage portion to reduce flow pressure between the inlet and outlet ends.
