What is V Notch Ball Valve?

The V–Notch Ball Valve gives non-clogging, high capacity, straight-through flow control of fluids containing pulp and paper stock or slurries and fluids containing suspended solids or fibrous materials.

V-Notch Ball Valve is a quarter turn valve with a segment Ball. The V-Ball creates a wedging and shearing effect to prevent the dragging of stock or slurry between the ball and its seal.

Applications of V Notch Ball Valve

V Notch Ball Valves – semiball valves are high-quality control valves for every type of process control application you may need. From the oil, gas, automotive, chemical, treatment, and power processing endeavors to the entire range of pharmaceutical, cosmetic, beverage, and food industries, there are ball valves available for your specific endeavor. Most are equipped with direct actuator mounts and pads for efficient automation and the variations of design and material ensure that your optimal performance standard is met.

V Notch Ball Valve – ball control valves are superior to competitors due to high-performance standards. Stainless steel ball valves, industrial or sanitary in design, are some of the many choices offered. Three-piece, flanged, double union, two-piece, three-way, grooved end, and high-pressure ball valves are perfect for the many ways ball valves are used in today’s market.

Most have direct mount actuator capabilities, some are available with appropriate actuators such as electric or pneumatic. This classic quarter turn style allows complete control over flow where the passageway needs to be completely closed. The ball valve can also provide a three-way option at points in the control loop requiring a T or L formation and the ability to shut off one or all of the connections.

V Notch Ball Valve – ball control valves work very well in situations where they are required to be idle for long periods of time, developing a few problems with inactivity. Whatever the flow requirement, there is a ball valve that can be considered appropriate for it, from the full port ball valve offering no flow restriction since the hole bored in the ball is the same size as the passage, to the standard port ball valve allowing a smaller flow with the bore in a ball the size of the passage itself, and including reduced port ball valves allowing significant flow restriction due to smaller bores in smaller balls. Any type of flow restriction can be completely shut off in high-pressure situations by actuating the rotation of the valve and sealing the passageway shut.

V Notch Ball Valve can help you determine the best valves for your facility. There are many types of valves, and the regulation of flow is inherently dependent upon the size and design of the control valves chosen for the system in place. The installed flow characteristic must be maintained at a sufficiently linear pace to stay within the specified parameters of the operating range of the system.

Features & Benefits of V Notch Ball Valve

• A bubble-tight shutoff valve and precision control valve combined in one
  • Standard round ported ball valves have been used, and continue to be used, for many control applications such as services involving moderate pressure drops. Now, with the development of Flow-Tek’s characterized V-balls, a full range of control applications is available with superior flow control. These 1/4-turn control ball valves are more compact, lighter-weight, and much less expensive than comparably sized globe valves and segmented control valves offered by other companies. Flow-Tek control valves offer fast response times to control signals due to advanced digital control of actuation and the inherent strengths of ball valves. These valves exceed Class VI offering bubble-tight shutoff with zero leakage. Other features include superior rangeability and repeatability, high flow capacity, the ability to function with fluids containing solids and fibers, ease of maintenance, and exceptional interface with PLCs and computer command signals. Flow-Tek high-quality pneumatic and electric control actuators are very durable and efficient.
• Increased Linear Response
  • Due to the in-line design inherent with characterized control ball valves, line media flows linearly through the piping system. The direct pattern provides increased media control and rapid response times to controller commands.
• Exceptional Characterized Control
  • Flow-Tek’s characterized balls provide predictable and accurate control of downstream flow rates. These precision-cut balls match the control performance of globe valves while offering the economy, features, and reduced size and weight of ball valves. Flow-Tek offers a wide range of V-Port and Slotted Port characterized balls. The standard characterized balls and an example of a custom ball are shown above. The 90° and 60° balls, like standard round hole balls, offer an equal percentage of inherent flow characteristics. A slotted ball and a V-Port ball with a small angle opening, such as a 15° ball, furnish a linear inherent flow characteristic. medium angle V-Port valves such as a 30° ball furnish a modified equal percentage inherent flow characteristic. Custom ports are also available to meet special control requirements. Designed with flexibility in process conditions in mind, the Cv and control characteristics are easily changed by simply changing the ball.
• High Rangeability
  • The characterized ball delivers controllable flow characteristics from the nearly closed to the fully open position of the valve. Though the port type and valve size affect the rangeability, Flow-Tek characterized balls have a minimum rangeability of 200:1 and can exceed 800:1. Flow rates are highly repeatable within the normal 20% – 80% range of travel.
• High Flow Capacity
  • Flow-Tek’s control ball valves have been designed to offer maximum flow characteristics that are substantially higher than comparably sized globe valves. The inherent flow pattern of ball valves increases flow rates and in many applications valves smaller than pipeline size can be used. The self-cleaning action of the ball against the seat makes the ball valve acceptable for slurry and high fiber media services.
• High-Pressure Drops
  • Engineered to withstand high-pressure drops while providing leak-free operation, the V-Control Series delivers the precision control required by today’s process industries. The δP limit for liquids is up to 500psi and steam is up to 300psi. Please consult the factory or your distributor for information on control valve sizing and pressure drop limitations.

CALCULATE V NOTCH VALVE SIZE

With the above information, the following steps are used to correctly size a valve in a piping system.

• Cv value is obtained by using the appropriate ANSI/ISA–75.01.01 flow sizing formula or computer-aided flow control sizing program that is based on these formulas.
• Cavitation is checked by using the FL value (Liquid Pressure Recovery Factor), and the expansion factor needed for compressible fluids is obtained using the values (Pressure Drop Ratio Factor). Both values are found in the Cv charts supplied on the following pages.
• Select a nominal valve size from the Cv charts based on the calculated Cv.
• V-Port Ball Valves: Select a valve that offers calculated Cv for the minimum and maximum flow between 20% to 80% of port opening.
• Round Port Ball Valves: Select a valve that offers calculated Cv for the minimum and maximum flow between 30% to 80% of port opening.
• Select the valve type (flanged, threaded, or welded) and materials of construction.
• Valtorc recommends RTFE valve seats for V-Ball Control Valve applications.
• Select the actuator – for Actuator Sizing please see our actuator product pages and IOM documents.
