V-Port Ball Valves


Series VP V-Port Ball Valves

Features:Ball Valves

    • VALTORC "VP" Series V-Port Ball Valves are ideal for achieving more precise control with the simplicity and sealing features of a ball valve.
    • We offer V-Port Ball Valves 1/2" - 4" in a 3-piece design and 1/2”- 6" flanged.
    • The standard "V" notch options are 30, 60 & 90.
    • While they are available as manual valves, we specialize in automating them to suit your particular control requirements.
    • V-Port Ball Valves offer better and more consistent control than traditional round ported ball valves.
    • We offer this valve with the control port cast and machined into the ball, not in the seat.
    • This allows for much better flow characteristics and eliminates the need to replace seats.

        V-Seat, V-Slotted , V-Ball Characterized Seat Control Valves

        We have a complete line of V-Port Ball Valves, V-Ball, V-seat and slotted seat control valves providing precision throttling control for a wide range of applications. As with our standard ball valves, V-characterized seated valves offer equal
        percentage flow characteristics. The slotted seated valves have an inherent linear flow characteristic.

        • Simplicity - Very low maintenance costs compared to globe and segmented ball valves
        • Tight Shutoff - Exceeding Class VI and bubble-tight
        • High Rangeability - Repeatable control through 95% travel
        • Low Cost - Purchase price is substantially lower than competitive high pressure drop valve
        • Low weight - about 30% lighter than globe control valve
        • Compact Size - Leaves more room for additional field equipment
        • Shearing Action - Non-clogging control of fibers and solids
        • Low Flow Control - Cv as low as 0.07
        • Flexible CV -Interchangeable seat angles or slots
        • Erosion Resistant - Extra tough, hardened seat and ball
        • High Pressure Drop - Liquids up to 500 psi, steam up to 150 psi
        • High Temperature - Up to 1,000°F

        A typical comparison for a 1" V-Port Ball Valve

        The CV graph shows the range of flow for the standard port, 60°V and 30° V ball valves. The characterized V seats provide finer control than round port valves.
