An apparatus is provided to test valves. The apparatus includes a base and an actuation mechanism with an actuator having a first end coupled to the base and a second end retractably extends from the base. The apparatus further includes a common platform with a first surface and a second surface. The first surface coupled to the second end of the actuator and moves from the base, based on an extension of the actuator. The apparatus further includes a plurality of engagement members each of which includes a first portion coupled to the first surface and a second portion coupled to the second surface. The apparatus further includes a plurality of sensors coupled to the plurality of engagement members such that each sensor of the plurality of sensors is coupled to corresponding member of the plurality of engagement members and coupled with a valve associated with a machine.
