Butterfly Valves
(1,259 companies)
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.
Ball Valves
(2,082 companies)
Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve gets its name from the ball that rotates to open and close the valve. Ball valves are used in situations where tight shut-off is required. They are wide duty valves, able to transfer gases, liquids and liquids with suspended solids (slurries). Ball valves provide tight shut-off and characterizable control. They have high rangeability due to the design of the regulating element and few complications from side loads typical of butterfly or globe valves.
Control Valves
(1,613 companies)
Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system.
Air Valves
(758 companies)
Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices.
Solenoid Valves
(986 companies)
Solenoid valves are devices that use a solenoid to control valve activation.
Gate Valves
(1,145 companies)
Gate valves and knife valves are linear motion valves in which a flat closure element slides into the media stream to shut off flow.
Double Sided and Transfer Tapes
(220 companies)
Double sided tapes are coated with adhesive on both sides of the backing or carrier. Transfer tapes consist of a thin adhesive film without a carrier or backing.
Mechanical Vacuum Pumps and Systems
(245 companies)
...to reciprocating pistons, but are not articulated. These pistons "rock" with eccentric motion of drive. Rotary piston - Rotary pistons or cams rotate eccentrically and evacuate air through a check valve on the "compression" or evacuation stroke...
Valve Actuators
(863 companies)
Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source.
Flame Detectors
(179 companies)
Flame detectors monitor and analyze incoming radiation at selected wavelengths.
HPLC Detectors
(49 companies)
High performance liquid chromatograph (HPLC) detectors pass a beam of light through a column effluent as the fluid passes through a low-volume flow cell. Variations in light intensity are recorded and a chromatograph is generated.
Current Testers and Detectors
(45 companies)
Current testers and detectors check for the presence of current flow in electrical circuits. They are also used to locate current in hidden wires and cables
Water Valves
(575 companies)
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.
Industrial Valves
(2,968 companies)
Valves are mechanical devices that control the flow and pressure of liquids, gases, and slurries within a system. They are also known as regulators and are used in a wide variety of applications. Valves vary greatly in size, design, function, and operation.
RF Phase Detectors and Comparators
(42 companies)
RF phase detectors and comparators are circuits or instruments that provide a DC output voltage proportional to the difference in phase between two RF signals.
