ABSTRACT:
A dual motion valve (A) includes two dual motion valve assemblies (10, 12) having a rotary input which allows the benefits of applying both rotary and axial motion to a rotary sealing element (24) having a plurality of ports (43). The motion of the rotary sealing element during actuation provides axial engagement of the rotary sealing element with a stationary valve plate (22) which also has ports (38). Fluid passages are created through the valve when the ports of the rotary sealing element are aligned with the ports of the stationary valve plate. Alignment is achieved through rotation of the rotary sealing element with respect to the stationary valve plate. The fluid passages provide direct paths which minimize fluid turbulence created in the fluid as it passes through the valve (A).
