Description du produit<\/h2>\n

This pneumatically actuated 3-way ball valve automates the diversion or mixing of fluids. The 316 stainless steel three-way body is paired with a rack-and-pinion air actuator (double acting or spring return) that rotates the ball 90\u00b0 on a signal from your PLC or remote switch. The body uses a high-platform ISO 5211 pad<\/strong>, so the actuator bolts straight onto the valve \u2014 no bracket, no coupling, no alignment work.<\/p>\n

Threaded PT, NPT or PF ends and a 1000 WOG rated body make this a drop-in automation upgrade for industrial piping. For hygienic lines, see our sanitary pneumatic 3-way ball valve<\/a>. If you operate the valve by hand, see the vanne \u00e0 bille manuelle \u00e0 3 voies<\/a>.<\/p>\n

L-Port or T-Port \u2014 Which One Do You Need?<\/h2>\n

This is the first decision to make, and it is the one buyers most often get wrong. The two ports look identical from the outside; the difference is the shape of the hole through the ball.<\/p>\n

    \n
  • L-Port (Diverter) :<\/strong> the bore is bent 90\u00b0, connecting the inlet to one<\/em> of two outlets at a time. Use it to switch flow from a common line to either of two destinations \u2014 for example, alternating between two storage tanks or two filter banks.<\/li>\n
  • T-Port (Mixing \/ Diverting):<\/strong> the bore is T-shaped, so it can connect the inlet to either outlet, or join two ports together. Use it to mix two streams into one, or to divert while keeping a branch live.<\/li>\n<\/ul>\n

    If you only need to send flow one way or the other, choose L-port. If you need to combine streams, choose T-port. Tell us the flow paths you need when you request a quote and we will confirm the port type.<\/p>\n

    Which Actuator Do You Need? \u2014 Selection Table<\/h2>\n

    The actuator size depends on the valve size and on whether you choose double acting or spring return. Spring return units are always one size larger<\/strong> than double acting, because part of the air pressure is used to compress the spring.<\/p>\n

    Avantages et b\u00e9n\u00e9fices<\/h2>\n
      \n
    • One valve replaces three:<\/strong> a single 3-way body does the work of two or three 2-way valves plus the fittings between them \u2014 fewer joints, fewer leak points, less space in the skid.<\/li>\n
    • Direct mount, no bracket:<\/strong> the high-platform ISO 5211 pad takes the actuator directly. Nothing to machine, nothing to align.<\/li>\n
    • Spring return on air loss:<\/strong> SR units return to their preset position automatically when the air supply is lost. Tell us which position you need and we will build it that way.<\/li>\n
    • 316 stainless throughout:<\/strong> the molybdenum in 316 resists pitting from chloride-bearing media \u2014 the usual reason 304 fails in coastal or brine service.<\/li>\n<\/ul>\n

      Applications<\/h2>\n
        \n
      • Chemical batching:<\/strong> switching automatically between ingredient lines.<\/li>\n
      • Temperature control:<\/strong> diverting fluid through a heat exchanger or around it, on a sensor signal.<\/li>\n
      • Water treatment:<\/strong> alternating between filtration banks without stopping the line.<\/li>\n<\/ul>\n

        FAQ<\/h2>\n

        Can I add an actuator to a manual 3-way ball valve later?<\/h3>\n

        Yes. The body has a high-platform ISO 5211 mounting pad, so the same valve can be supplied with a lever today and fitted with a pneumatic actuator later \u2014 no bracket, no coupling, no re-piping. Give us the ISO flange code from the table above (F03 to F07) and we will match the actuator.<\/p>\n

        What is the difference between an L-port and a T-port 3-way ball valve?<\/h3>\n

        An L-port bore is bent 90\u00b0 and connects the inlet to one of two outlets at a time \u2014 it diverts. A T-port bore is T-shaped and can connect the inlet to either outlet or join two ports together \u2014 it can mix as well as divert. Choose L-port for switching, T-port for mixing.<\/p>\n

        Which actuator size do I need for my valve?<\/h3>\n

        For double acting: 1\/4\u2033\u20133\/4\u2033 uses T50, 1\u2033\u20131-1\/4\u2033 uses T63, 1-1\/2\u2033 uses T75, 2\u2033 uses T88. For spring return, go one size larger in each case. The full selection table is above.<\/p>\n

        Is a 3-way pneumatic ball valve the same as a solenoid valve?<\/h3>\n

        No. A solenoid valve is operated directly by an electrical coil and is normally used on small, clean lines. This valve is a full-bore ball valve turned by an air actuator \u2014 it handles higher pressure, larger sizes and dirtier media. A solenoid valve is often used with<\/em> it, as the pilot that switches the air supply to the actuator.<\/p>\n

        Double effet ou retour par ressort : lequel choisir ?<\/h3>\n

        Double acting uses air to open and air to close, and holds its last position if air is lost. Spring return uses air one way and a spring the other, so it returns to its preset position when air is lost. Choose spring return when the line must not be left in an unknown state; choose double acting when you want the valve to hold position.<\/p>\n

        What thread types are available?<\/h3>\n

        PT (BSPT), NPT and PF (G) threads are available. Tell us which standard your piping uses when you request a quote.<\/p>","protected":false},"excerpt":{"rendered":"
