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.
|
|
Gate valves and knife valves are linear motion valves in which a flat closure element slides into the media stream to shut off flow.
|
|
Globe valves are linear motion valves with rounded bodies, from which their name is derived. They are widely used in industry to regulate fluid flow in both on/off and throttling service.
|
|
Industrial valves are classified in many different ways. They can be distinguished by material of construction, media handled, and/or application.
|
|
Limit switches are electromechanical or solid state devices that require the physical contact of an object with the switch’s actuator to make the contacts change state.
|
|
Pinch valves include any valve with a flexible elastomer body that can be pinched closed, cutting off flow, using a mechanism or fluid pressure.
|
|
Pressure regulators are used to maintain a constant outlet pressure or flow.
|
|
Rotary limit switches use physically-actuated levers to rotate a shaft and operate the contacts in a switch, making them change state.
|
|
Sanitary valves are designed for applications requiring clean or sterile processing.
|
|
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.
|
|
Valve positioners compare a control signal to a valve actuator’s position and move the actuator accordingly. They are used with both linear valves and rotary valves.
|
|
Water valves are designed to handle and control hot water, cold water, ground water, potable water, salt water and/or wastewater. They are made from metal or plastic.
