Sub-Categories
  • Plast-O-Matic ABR Series Pneumatic Actuators Plast-O-Matic ABR Series Pneumatic Actuators
    Models & Types:
    Series ABRA is a double-acting actuator for 1-1/4", 1-1/2" and 2" ball valves; it uses air pressure to open and air pressure to close. Manual override is standard. Requires 30 to 50 PSI compressed air.
    Series ABRS is a fail-safe actuator for 1-1/4", 1-1/2" and 2" ball valves; it uses a spring return for either normally closed or normally open operation. Converts easily from normally closed to normally open. Requires 60 to 80 PSI compressed air.
    Series ABMS is the same fail-safe actuator as ABRS, except that it has the added convenience of manual override. Requires 60 to 80 PSI compressed air. Designed for 1-1/4", 1-1/2" and 2" ball valves.

    Actuator Features:
    • Compact design -- very small footprint.
    • Plastic construction is ideal for corrosive atmospheres; successfully used in battery filling plants, printed circuit board fabs, electroplating shops and other harsh environments.
    • Light-weight assembly -- less piping stresses and lower shipping costs.
    • Long cycle life -- tested for millions of cycles.
    • Quick and easy attachment to valve body mounting lugs.
    • Can also be hydraulically actuated.
    • Designed for low maintenance.

    True Blue Ball Valve Features:
    • Long cycle life with Trunnion design -- valve mounts in either direction with no danger of ball "blow out."
    • Dual shaft seals eliminate leakage.
    • Reinforced actuating shaft (or stem).
    • True union ends -- socket or threaded. Flanges, metric & BSP ends optional.
    • Self-compensating PTFE seats.
    • Perfectly round and highly polished ball.
    • Rugged construction, known as "The Engineered Ball Valve."

    Plast-O-Matic ABR Series Pneumatic Actuators

  • Plast-O-Matic ABV Series Pneumatic Actuators Plast-O-Matic ABV Series Pneumatic Actuators
    The ABVA requires a 4-way air solenoid valve (Part # 8345G1), and ABVS requires a 3-way air solenoid valve (Part # 8320G13) to control actuation. Compressed air should be filtered and lubricated. The hex nuts used to mount the actuator are tapped to facilitate piping support.

    Manual Override
    Series ABVA and ABVS have direct override to the ball valve shaft. Series ABVS requires simple loosening of the spring prior to manual override.

    Materials of Construction
    Actuator is constructed of corrosion resistant thermoplastics. Seals are Buna-N. For optional materials, please consult factory.

  • Plast-O-Matic EBV Series Electric Actuators Plast-O-Matic EBV Series Electric Actuators
    Series EBV Actuators have many clear and important advantages:

    •  Manual override is direct to valve -- not through a gear train -- to eliminate potentially hazardous conditions. Do not consider a valve actuator without manual override unless you have a convenient and regularly tested shutoff capability as backup.
    •  Many "discount" actuators are not thermally protected. They could potentially run and run until overheating leads to failure or even fire.
    •  Series EBV position indicator is mechanically attached to the valve shaft and the running lights are wired to the motor. Indicator lights on most low cost actuators are electrically wired to your supplied signal. If the valve is jammed, if the motor burns out, if the gear box strips -- the light will not indicate the position of the valve -- it simply indicates your electrical signal.

  • Plast-O-Matic Limit Stops Plast-O-Matic Limit Stops
    A True Blue air actuated ball valve with a limit stop can maintain any desired set flow from virtually closed up to full capacity of the valve. Two types are available, one for air x air actuators (Actuators ABVA & ABRA) and one for air x spring "fail safe" actuators (ABVS & ABRS). A simple stainless steel adjusting screw is used to limit the stroke of the air actuator position. Turning the adjusting screw clockwise limits the opening of the ball valve. The limits stops can also be used with limit switches for throttling.

  • Plast-O-Matic Limit Switches Plast-O-Matic Limit Switches
    Series SW signals the open or closed valve position for computer verification or to actuate other equipment based on the valve position. Body material is PVC, seals are BUNA-N, and the assembly fasteners are stainless steel and can be shielded from the atmosphere if necessary. Of course none of these materials in the Limit Switch are in contact with the process liquid. The Limit Switch has a camshaft and two single-pole double throw switches. A signal line is wired "through" the switch to the equipment or computer being signaled. A 1/2" NPT conduit fitting seals the wiring connection. AC resistive load rating is 10 amps for each contact. DC loads are rated for 60W (5A at 12 VDC, 2.5A at 24 VDC). The switches make contact when the valve is either open or closed. The open position of the True Blue ball valve is adjustable for throttling by using the optional Series LS Limit Stop. Series SW Limit Switch is also adjustable to accommodate the throttle open position.
