Features & Benefits
Efficient 1/4-Turn Control Valves
A bubble-tight shutoff valve and precision control valve are combined into one compact solution. The introduction of characterized V-balls has expanded control applications, offering superior flow management in a smaller, lighter, and more cost-effective design compared to traditional valves. These valves provide fast response times, zero leakage, and easy maintenance, making them ideal for a wide range of applications.
Increased Linear Response
The straight-through design of characterized control ball valves allows fluid to flow without obstruction, creating a more efficient and streamlined flow path. This design minimizes pressure drop and turbulence, resulting in improved control and stability of the flow. The direct flow path enhances the valve’s ability to regulate fluid with greater accuracy, providing more precise adjustments in response to commands from the controller.
High Rangeability
The characterized ball in the valve allows for precise control of flow from almost closed to fully open. Although the type of port and valve size affect rangeability, these balls provide a minimum rangeability of 200:1, with the possibility of reaching up to 800:1. The flow rates stay consistent, especially within the usual 20% to 80% range of valve movement. This high rangeability ensures precise modulation even in applications with varying flow demands.
Exceptional Characterized Control
Characterized balls provide precise control of flow rates, similar to globe valves, but with the advantage of using smaller, lighter ball valves. They come in different types, like V-Port and Slotted Port, each offering specific flow patterns, from equal percentage to linear. These valves are versatile because you can change the ball to adjust the flow rate and control settings, making them suitable for various process requirements.
High Flow Capacity
Control ball valves are designed to offer excellent flow characteristics, often outperforming similarly sized globe valves. The way ball valves are built helps increase flow rates, sometimes even allowing the use of smaller valves than the pipeline size. Moreover, the ball’s ability to clean itself against the seat makes these valves ideal for handling slurry and high-fiber media.
High Pressure Drops
Built to manage high-pressure drops and deliver leak-free performance, the V-Control Series provides the precise control needed in today’s process industries. These valves can handle pressure drops of up to 500 psi for liquids and 300 psi for steam. For specific information on valve sizing and pressure drop limits, it’s recommended to contact the manufacturer or your distributor.
Bidirectional Bubble-Tight Shutoff
The V-Control Series ball valves provide bi-directional, bubble-tight shutoff that meets Class VI requirements in accordance with FCI 70-2 standards. These valves are designed for precise control in demanding applications, ensuring zero leakage in both directions.
V-PORT BALL CONTROL VALVES
V-Port Ball Valves are designed to provide the performance and reliability needed for improving process operations. These valves are adaptable, capable of handling fibrous suspensions, as well as managing clean, dirty, viscous, and corrosive liquids and gases. They are available in ASME Class 150 for sizes ranging from 1 to 20 inches and in ASME Class 300 for sizes from 1 to 12 inches.
With a one-piece body construction, these valves offer flanged or flangeless end connections. Meeting or exceeding North American and International Standards, the ball’s geometry allows for precise flow control. A secure ball-to-shaft connection ensures consistent operation, while bearings, covers, and fasteners are designed for durability.
Streamlined Flow Passages
V-Port Ball Valves feature a streamlined flow passage that optimizes the flow coefficient (Cv/Kv) for each valve size, ensuring maximum efficiency and accurate flow control. This design minimizes turbulence and pressure drops, allowing for smoother fluid movement through the valve. By reducing flow disruptions, the valve can handle higher flow rates with less wear on its internal components.
Durable Design
The heavy-duty cast body of the V-Port Ball Valve features a one-piece design, enhancing the integrity of the installed piping and reducing potential leak points. Made from stainless steel with drop-in seats and a splined shaft and ball connection, this valve is designed for easy maintenance.
V-Ball Design
The V-Ball is engineered for precise control in handling fibrous suspensions and various liquids and gases, with a straight-through flow passage that maximizes efficiency and resists erosion. The ball is available in high-alloy materials with a nickel overlay for added corrosion resistance, and options like 317 stainless steel with tungsten carbide or Hastelloy C with nickel are offered for more demanding applications.
Protected Bearings
The sealed-bearing option stops media from entering the bearing areas, which could interfere with valve operation. For bearings that require extra protection from scaling, plating, or abrasive and polymerizing media, PFA Fluoropolymer or FFKM Perfluoroelastomer seals are available.
Durable Bearings
The one-piece bearing offers strong radial support to the shaft, helping to reduce wear and prevent fatigue. Made from 317 stainless steel with reinforced PTFE, it has a low friction surface, which minimizes the effort needed to operate the valve and allows for smaller actuators. For more demanding conditions, a cobalt-chromium alloy bearing can be used, and a sealed-bearing option is also available for added protection.
Secure Shaft Connection
The splined shaft with a solid ball-to-shaft connection on V-Port Ball Valves offers a strong, reliable link that prevents any mechanical slippage. This design, featuring a locking torque screw, ensures precise positioning of the ball for accurate control. Additionally, the machined shaft diameter provides protection against blowouts.
Quick-Adjust Ball and Seat
The VPB valve’s self-aligning ball and seat design makes repairs and reassembly quicker by reducing setup time. Valves can be restored to like-new performance without needing complicated procedures. The spring-loaded metal seat also allows the ball and seat to automatically adjust for wear, ensuring continued reliable operation.
Applications
The V type ball valve is suitable for pipelines ranging from Class 150 to Class 300 and can be used for flow control or complete flow cut-off. It offers multiple operation modes, including manual, pneumatic, electric, and worm gear, depending on the specific application requirements. With the right materials, this valve can effectively handle various media such as water, steam, oil, liquefied gas, and more.
STRUCTURAL FEATURES
The V type ball valve adopts disc or cylindrical spring loaded moveable metal seat structure provided with compensation character, so no problems such as blocking or release of V type ball valve and seat will occur. The sealing is reliable and the service life is long.
Reliable Sealing
The V type ball valve features a disc or cylindrical spring-loaded movable metal seat structure, which automatically compensates for wear. This design prevents issues like blockage or release between the ball and seat, providing dependable sealing and a long service life.
Shearing Action
The V-shaped notch in the ball delivers a shearing action, making this valve ideal for handling high-viscosity media, such as those containing fibers, solid particles, slurry, and pulp. This feature allows for smooth operation even in challenging conditions.
Mayor durabilidad
Depending on the service conditions, the metal seat and ball surfaces can undergo advanced treatments, such as nickel-base alloy spray welding (HRC≥60) or tungsten cobalt alloy HVOF coating (HRC≥70). These treatments make the valve suitable for severe environments and enhance its durability.
Efficient Flow
When fully opened, the V type ball valve offers high flow rates with minimal pressure loss, and the media does not accumulate in the valve’s middle cavity. The valve has equal percentage flow characteristics, a wide adjustment range with a maximum ratio of 100:1, and provides precise control and reliable positioning.
Diseño compacto
The V type ball valve is compact and highly adaptable, offering excellent sealing performance. It can effectively replace other types of valves, such as gate valves, globe valves, and standard ball valves, in various applications.
