Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves.
Gear pumps use intermeshing gears to pump various types of liquids. Typically, one gear is the driver and the other is free wheeling. The gears have very tight tolerances so that the fluid being pumped cannot pass through them. Common uses for gear pumps include high pressure, metering, and flow control applications.
Hydraulic valves contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems. They range from simple shutoff valves to precision control valves.
Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement).
Joystick controllers use potentiometric, inductive or photoelectric sensing systems and/or switches to translate joystick motion into an output signal.
Signal amplifiers accept signals from sensors and other devices and amplify them to levels suitable for further processing or digitization by computer elements.
Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards.
