Abstract: A modular fluid power valve assembly having a valve controlling fluid flow from an inlet to an outlet port. The valve can be positioned on a manifold that houses a control assembly used to selectively activate the valve. The control assembly includes a visual indicator to indicate the actuation of the valve. The visual indicator further includes a light source for emitting light. A light pipe is selectively removably attached to the control assembly and valve manifold to allow the light from the light source to be easily seen by the user. The light pipe can be made in a variety of shapes and colors and can be removed by hand for maintenance.

Abstract: A circuit board, which includes one or more sensors, is integrated in a fluid control device, such as a valve manifold and a base plate. The fluid control device selectively directs a fluid used to control pneumatic or hydraulic equipment. The sensors are used to measure physical characteristics of the fluid, such as flow rate, pressure, and temperature. A flow sensor includes a paddle and a support member. The paddle is disposed at least partially in an orifice and is displaced in response to fluid flow. The support member positions the paddle in the orifice and includes a plurality of strain gauges. The strain gauges are disposed on only one side of the support member and are mechanically stressed in response to the paddle being displaced by the fluid flow.

Abstract: A fluid power interlock system and method for providing same including a circuit having a first valve shiftable between a first and second state having an input and a pair of selectively operable first outputs. One of the first outputs is operatively connectable to a first actuator and the other of the first outputs is operatively connected to a second valve shiftable between a first and second state. The second valve has a pair of selectively operable outputs, one of the second valve outputs is operatively connectable to a second actuator, and the other of the second valve outputs is operatively connected to the first valve and provides a pilot signal thereto for permitting the first valve to shift from a first state to a second state. Shifting state of either of the first and second valves interrupts the pilot signal thereby preventing the non actuated valve from being actuated and shifting state. The system may also include a manifold, wherein the first and second valves are secured to the manifold.
