Check Valves - (1634 companies)The mechanics of check valve operation are relatively simple. Most check valves contain a ball that sits freely above the seat, which has only one through-hole. The ball has a slightly larger diameter than that of the through-hole. When the pressure behind... Search by Specification | Learn More -
Valve Actuators - (731 companies)Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source. There are several basic types of valve actuators: manual, electric, pneumatic, and hydraulic. Manual valve actuators do... Search by Specification | Learn More -
Industrial Liquid Handling Pumps - (2258 companies)...linear rather than rotary motion. They operate by moving a piston or diaphragm back and forth through a cylinder. Fluid moves in at the upstroke (suction) and out through a check valve on the down-stroke (discharge). The image below shows a simplified... Search by Specification | Learn More -
Valve Repair Services - (142 companies)Valve repair services repair and rebuild used valves. They may perform blast cleaning and degreasing operations, apply corrosion-resistant and anti-wear coatings, and provide non-destructive evaluation (NDE) test and inspection. Valve repair...

Valve Positioners - (175 companies)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. When a control signal differs from the valve actuator 's position, the valve... Search by Specification | Learn More

Manual Valve Actuators - (92 companies)Manual valve actuators do not require an outside power source. They use a handwheel or lever to drive a series of gears whose ratio results in a higher output torque compared to the input (manual) torque. Manual valve actuators do not require...

Sizing up flow forces
Determine forces on the valve spool to optimize solenoid size. Precisely calculating flow forces in spool valves lets designers maximize flow and minimize solenoid size. For instance, relatively small coils operate a 16-gpm threeposition, fourway Sterling Hydraulics GS0657 Series valve. Flow forces...
