  • Pneumatic Valve Actuators-Image
    Pneumatic Valve Actuators - (427 companies)
    Pneumatic valve actuators adjust valve position by converting air pressure into linear or rotary motion. There are two main forms: the piston actuators and diaphragm actuators. Piston actuators are used when the stroke of a diaphragm actuator would...

  • Air Valves-Image
    Air Valves - (799 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. Air valves allow metered flow of fluid in one or both...

  • Solenoid Valves-Image
    Solenoid Valves - (980 companies)
    Solenoid valves are devices that use a solenoid to control valve activation. They are considered electromechanical control devices used to control liquid or gas flow. An electrical current runs through a coil to control the valve by moving a plunger...

  • Check Valves-Image
    Check Valves - (1927 companies)
    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. Check valves are self-activating safety valves...

Flow specifications based on Japanese test standards tend to overstate performance. Vice President for Research & Development Most design engineers select pneumatic control valves based on performance data published by the valve manufacturer. Usually the key performance factor is how much air...

Show More

Look at flow coefficient, cylinder bore, and rod speed to best match pneumatic actuators and valves. In recent years, much discussion has centered on ratings (also known as capacity coefficients or flow factors) and whether or not American, European, and Japanese pneumatic-valve manufacturers rate...

Japanese test methods better predict pneumatic valve performance. SMC follows the latest ISO standards when rating pneumatic valve flow in terms of sonic conductance. Full stroke time of a pneumatic cylinder is inversely proportional to the maximum exhaust flow rate. represents the maximum constant...

Consider every system component to ensure top performance with minimal losses. I am disappointed every time I see the flow coefficient used to size a valve without consideration given to the other components in a pneumatic circuit. In the old days, a focus on the valve alone often worked because...

Most pneumatic system designers are familiar with the flow coefficient as a means of gauging flow through various fluid-power components. Unfortunately, there is a common misconception in the industrial community that doubling a valve's flow coefficient, or conductance, , cuts actuator stroke time...
