    TECH TIPS: POPPETS VS. SPOOL VALVES - WHY VALVE TYPE MATTERS


    When selecting 2-Way and 3-Way valves for your pneumatic circuit, be sure to take the internal design of the valve into consideration. Though the function is overall the same, use of a poppet or a spool valve can impact your you application in unforeseen ways.

    Both valve types boast their own advantages. Poppet valves provide faster response times and a higher flow rate. Spool valves can be used in a vacuum and are not affected by pressure, requiring less force to actuate the valve. Pneumadyne manufactures a variety of of poppet and spool valves to accomodate your application needs.

  • Flow Control Valves
    TECH TIPS: THE DIFFERENCE BETWEEN A FLOW CONTROL AND A NEEDLE VALVE IS EXPLAINED

    Flow controls and needle valves are both used in reducing the rate of flow in a leg of a pneumatic circuit, and the terms are often used interchangeably, but there are a few key differences between the two products.

    Flow controls control media flow in only one direction, allowing free flow in the opposing direction, while needle valves control media flow in both directions. Both feature finely threaded stems to allow gradual adjustment of the flow.

    Additionally, there are two separate kinds of flow controls: media-in and media-out. Media-in restricts the influx flow to an actuator, while media-out restricts the exhaust flow.

  • Pressure Regulators

    The primary purpose of pressure regulators is to control pressure with close tolerances to ensure that compressed air in a pneumatic system is not wasted. Pressure regulating valves accomplish this by maintaining constant output pressure under various input pressures and output flows. Pressure regulators are used for various home, medical and industrial applications such as home furnaces, tanks for oxygen and anesthesia gases, and pneumatic automation systems.

    Installing a pressure regulator that is too large for your system will increase air usage and waste energy. Therefore, properly sizing and setting your pressure regulator is crucial for efficient air consumption. Additional considerations for selecting a pressure regular for your pneumatic vale system include

    • Operating pressure for outlet and inlet
    • Maximum flow requirements for your pneumatic system
    • Requirement of additional pneumatic valve accessories
    • Material compatibility with the fluids or gases used in your application
    • Features such as port type and knob style

    Pressure Regulator Functions and Features

    Pressure regulators are manufactured for a range of fluid, gas and air applications. They are offered in numerous configurations, but all typically contain the same three functional elements: a valve that reduces or restricts pressure, a component that senses pressure and a control element that reduces or restricts pressure.

    To meet the needs of your pneumatic application, Pneumadyne manufactures relieving pressure regulators, and miniature precision pressure regulators. A variety of porting options are also available for plumbing convenience.

    • Relieving Pressure Regulators are engineered to maintain a constant, preset downstream pressure.
    • Miniature Precision Pressure Regulators provide highly accurate pressure control in a compact package.

    Pneumatic pressure regulators from Pneumadyne provide a range of features and benefits including:

    • Numerous sizes & styles available to meet your needs
    • Swivel ports for critical alignment
    • Anodized & plated for corrosion resistance
    • Direct gauge mount to output (11 Series)
    • Mounting versatility

  • Quick Exhaust Valves
    PRODUCT SPOTLIGHT: QUICK EXHAUST VALVES

    Commonly referred to as QEV valves, or quick dump valves, Quick Exhaust Valves are designed to increase the cycle speed of a cylinder in a pneumatic system. Depending upon your actuation requirements, installing a pneumatic Quick Exhaust Valve at the blind end or rod end of your cylinder will result in rapid detraction or rapid extension. When pressure is removed from the valve's input port, backflow at the output port will unseat the internal components, relieving large amounts of flow in a minimal amount of time.

    To meet the unique plumbing needs of your application, Pneumadyne manufactures a wide variety of QEV valves with threaded or push-to-connect ports.

  • Shuttle Valves

    Installing a pneumatic Shuttle Valve quickly and easily allows the actuation of a cylinder or control valve from two or more locations. Also known as "OR" valves, Shuttle Valves automatically select the higher of two pressures allowing flow from one input to the output port. Simply connect your control valves to the shuttle's input ports and actuate either valve to shift the metal core and block the opposite input port. The internal design of Pneumadyne’s Shuttle Valves provides a low cracking pressure, allowing media to quickly flow through the output port to the cylinder or valve at the end of your circuit.

    Pneumadyne manufactures a wide variety of pneumatic Shuttle Valves which feature:

    • Threaded, barbed and push-to-connect ports for plumbing convenience
    • Low cracking pressure to quickly allow flow to the output port
    • Electroless nickel plated & black anodized body for corrosion resistance
    • Swivel ports for critical alignment
    • Compact size for limited space applications
