A liquid flow path assembly is removably secured to the mount and has an inlet configured to receive liquid, an outlet configured to dispense liquid and a passageway fluidly coupling the inlet to the outlet. A third aperture apart from the inlet and the outlet is fluidly coupled to the passageway and forming a valve guide. The liquid flow path assembly is disposed on the mount to align the third aperture with the mount aperture. An elongated valve has a valve stem guided by the valve guide and extends through the third aperture and the mount aperture. A latch assembly secures the liquid flow path assembly to the mount. ## Claims ### Claim 1 A flowable material dispenser, comprising: a mount having a mount aperture; a flow path assembly removably secured to the mount, the flow path assembly having inlet configured to receive and an outlet configured to dispense and a passageway fluidly coupling the inlet to the outlet, the flow path assembly including a third aperture apart from the inlet and the outlet fluidly coupled to the passageway and forming a valve guide, the flow path assembly disposed on the mount to align the third aperture with the mount aperture; a elongated valve having a valve stem guided by the valve guide and extending through the third aperture and the mount aperture; and a latch assembly configured to secure the flow path assembly to the mount, the latch assembly mounted on one component comprising the mount or the flow path assembly, the latch assembly having a movable latch member to releasably engage a securing member on a second component of the mount or the flow path assembly. ### Claim 2 (depends on 1) The dispenser dispenser of claim 1 wherein the latch assembly is secured to the mount and the securing member is disposed on the flow path assembly. ### Claim 3 (depends on 1) The dispenser of claim 1 wherein the securing member is detachably coupled to the mount or the flow path assembly. ### Claim 4 (depends on 1) The dispenser of claim 1 wherein the flow path assembly comprises two separable and mateable portions. ### Claim 5 (depends on 4) The dispenser of claim 4 wherein a first mateable portion includes the inlet and a second mateable portion includes the outlet. ### Claim 6 (depends on 5) The dispenser of claim 5 wherein the first mateable portion and the second mateable portion are joined together to form a portion of the passageway into which the valve stem extends. ### Claim 7 (depends on 4) The dispenser of claim 4 wherein the securing member is disposed on the second mateable portion. ### Claim 8 (depends on 7) The dispenser of claim 7 wherein the securing member includes an elongated portion forming a shield covering at least a portion of the flow path assembly. ### Claim 9 (depends on 1) The dispenser of claim 1 wherein the passageway comprises a first portion through which the valve stem extends and a second portion fluidly coupled directly to the first portion and extending away from the first portion toward the inlet, wherein a second longitudinal axis along which material flows toward the first portion forms an oblique angle with a longitudinal axis of the valve stem. ### Claim 10 (depends on 9) The dispenser of claim 9 wherein the oblique angle is an acute angle in a range of about 40 to 85 degrees. ### Claim 11 (depends on 9) The dispenser of claim 9 wherein the oblique angle is an acute angle in a range of about 40 to 60 degrees. ### Claim 12 (depends on 9) The dispenser of claim 9 wherein second longitudinal axis extends though the inlet. ### Claim 13 (depends on 1) The dispenser of claim 1 and an actuator coupled to the valve stem to axially displace the valve stem along a longitudinal valve stem axis in at least one direction. ### Claim 14 (depends on 1) The dispenser of claim 1 wherein the mount includes detachable portions proximate the inlet. ### Claim 15 (depends on 14) The dispenser of claim 14 wherein the detachable portions form an aperture configured to receive the inlet and engage portions of the flow path assembly proximate the inlet. ### Claim 16 (depends on 15) The dispenser of claim 15 and at least one displacement assembly to control movement of at least one of the detachable portions of the mount toward and away from the other detachable portion. ### Claim 17 (depends on 16) The dispenser of claim 16 wherein the displacement assembly includes an elongated rod joined to one of the detachable portions. ### Claim 18 (depends on 17) The dispenser of claim 17 wherein the displacement assembly includes a pivoting lever to control movement of the elongated rod. ### Claim 19 (depends on 16) The dispenser of claim 16 and further comprising a second displacement assembly disposed on the mount on an opposite side of the inlet from the displacement assembly.
