Ball valves provide tight shut-off and characterizable control. They have high rangeability due to the design of the regulating element, without the complications of side loads typical of butterfly or globe valves.
Butterfly valves control flow through a circular disc or vane by turning the valve's pivot axis at right angles to the direction of flow in the pipe. They are normally used as throttling valves to control flow.
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. 
Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system.
Data acquisition is the digitizing and processing of multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes. Signal conditioning includes the amplification, filtering, converting, and other processes required to make sensor output suitable for rereading by computer boards.
Data loggers and data recorders acquire digital data from sensors and other signals. They are primarily used to store data for subsequent downloads to a host PC, but may also include real-time features such as monitors and alarms.
Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.
Industrial filtration equipment is used to filter, thicken or clarify a mixture of different elements.
Industrial valves are classified in many different ways. They can be distinguished by material of construction, media handled, and/or application.
Level controllers monitor, regulate, and control liquid or solid levels in a process.
Liquid flow meters are used for measuring the flow or quantity of a moving fluid.
Volumetric liquid flow switches are devices with a switch output used for measuring the flow or quantity of a moving fluid in terms of a unit of volume per unit time, such as liters per minute. 
Manifolds and manifold systems are fluid-distribution devices. They range from simple supply chambers with several outlets to multi-chambered flow control units including integral valves and interfaces to electronic networks.
Mixing valves combine the flow of two or more inlets into a single outlet for applications such as temperature and concentration control.
Pressure regulators are used to maintain a constant outlet pressure or flow.
Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line.
Sanitary valves are designed for applications requiring clean or sterile processing. 
Sight flow indicators provide a quick, reliable and economical way to verify the flow of fluids through industrial process lines.
Solenoid valves are devices that use a solenoid to control valve activation.
Steam traps are automatic valves that release condensate from a steam space while preventing the loss of live steam. They also remove air and noncondensables from the steam space.
Steam valves are used to control the flow and pressure level of steam and heated water vapor.
Strainers are placed in-line with process piping to remove large solid contaminants from the flow.  Strainers can be cleaned and reused.
Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source.
