A V port ball valve starts opening when the valve operator turns the handle or turns on the actuator for a quarter turn. Pressure: Medium Pressure. A V notch ball valve body is perfect for erosive and viscous fluids and slurries with entrained solids.
Many times, we discuss how advancing technology enables breakthrough innovations in Industrial Automation. Applications include the power industry, paper industry, sewage treatment plants, and petroleum refineries. 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. V-Ball valves are low cost comparable to valves of similar pressure drops and Cv's with low flow control (as low as 0. Each product is engineered and built fit-for-purpose. The notching of the ball or disk is a V-shaped aperture, and it can be made out of any material needed to support the application. At the same time, a large shear force will be generated between the segment ball and the seat during the movement. When the handle starts rotating, it simultaneously rotates the stem and the ball. The flow controlled by a V notch ball valve is almost linear. V notch ball valves work by turning the ball quarter turn to open or close the valve which takes a second. ACCESSORIES: Electro pneumatic positioner, AFR, SOV, MOR, Gear Box, Limit switch & Position indicator.
Its V-notch Ball design provides accurate and reliable control in a wide range of applications. Segment Ball Valve Basic Character: V port ball valve has either a 'v' shaped ball or a 'v' shaped seat. Features of a V port ball valve. The sand casting foundry occupis over 130. V-notch Ball Valve Factory 322 products found from 8. 7%Al2O3, SSIC, STC, Si3N4. Tight shut off leakage class VI. Our v notch ball control valves can be manually configured or actuated for automated handling and control.
V notch ball control valve balls machined to a super smooth surface, hard chrome plated and polished to increase ball seal life. V port ball valves provide bubble-tight shut-off. Troubleshooting V port ball valves. End connection: Tri clamp, SMS Coupling, SW, BW, NPT, BSP, Flanged. ANSI V port Ball Valve. The direct pattern provides increased media control and rapid response times to controller commands.
Increased Linear Response. We provide our customers with everything from simple on-off packages to throttling applications, high pressure gas systems, over pressure protection and emergency shutdown assemblies. V notch ball valves are used to control and modulate flow, and they offer a high level of stability in comparison with other valves. This non-clogging and high-capacity valve are mostly used in pharmaceutical, beverage and food industries, cosmetic industries, etc. Figure: Three piece V port ball valve. Shut Off Classification. This type of design requires a generally more robust construction due to higher velocities of the fluids, which might damage a standard valve. The v notch ball control valve is a low-maintenance valve with a tight bubble shut-off function. Most have direct mount actuator capabilities, some are available with appropriate actuators such as electric or pneumatic. Flow Characteristic.
Leakage through the V port ball valve. The rotation is also of a quarter turn or 90o angle. Disadvantages of V-port ball valves. Ball Valve Downloads. We are prestigious industrial V-Notch Ball Valve manufacturer and supplier of Industrial Casting Ball Valves in Wenzhou. Thus, gaseous velocities are maintained at reasonable values throughout the valve and high noise levels are simply not generated. It also can be retrofitted and installed into any existing Fisher Vee-ball valve. We can assemble all possible accessories to ceramic V ball valves per customer's requirements, such as pneumatic actuators, limit switch, electric-pneumatic petitioners, solenoid valves, filter and regulators, and smart electric actuators, etc. Especially if medium is both abrasive and corrosive, the only way is choosing a right material; there is no better way to solve this problems. Side entry V port ball valves are made from forge metallic material. Technical Specifications. Reduces the gaseous noise in control valves. A V-notch ball valve helps to produce an equal percentage of fluid flow characteristics for better fluid flow control.
A V-port ball valve has the advantage of being used as a control valve which is not common in most ball valves. 04 for flangeless, ASME-B-16. The resultant pressure recovery raises the fluid pressure back above the vapour pressure, causing the vapour bubbles to collapse or implode. This results in sticking and galling as dirt and other material become trapped between the sliding plug and the inside surface of the anti-cavitation device. Maximum Pressure - Temperature Ratings. A slotted ball and a V-Port ball with a small angle opening, such as a 15° ball, furnish a linear inherent flow characteristic. You can also connect and interact with other rotary valve experts in the Valves, Actuators & Regulators group in the Emerson Exchange 365 community. 104 Class V; soft seal V-shaped ball valve conforms to ANSI B16.
Especially suitable for control systems requiring large adjustment ratios and control of fluids containing fibers and slurries. Bubble Tight Shut-Off. V-Port Ball Valves for Recycle Reject Flow Control Applications 15. Annual output exceeds 10000 tons including all kinds of material like grey iron GG15, GG20, GG25, GG30, ductile iron GGG400-18, GGG500-7, GGG600-3, and GGG700-2, high-Chrome cast iron KmTBCr26, high-nickle casting iron D-5S, and also Austempered Nodular Iron. He describes the problems cavitation cause: Cavitation poses serious problems for control valves, especially in high-flow and high-pressure-drop applications. 309 Liuhe Road, Binjiang District, Hangzhou, 310053, China. 104 Class Ⅵ. Zhejiang SUPCON Fluid Technology Co., Ltd. V port ball valves need to be made of strong materials as they work on high-velocity fluids which can damage them unless they are strong enough. Performance advantages. Some of the actuators that can be used in a V port ball valve include a hydraulic actuator, pneumatic actuator, and electric actuator. Special care is given to the mechanical connection between shaft and ball, which is splined using precise EDM techniques for maximum grip to avoid any lost motion or dead band.

PTFE+ graphite v-shaped packing, flexible graphite ring packing, graphite +PTFE braided packing etc. Usage/Application: Industrial. A yoke with ISO 5211 mounting pad is provided along with bare stem ceramic V ball valves for easy installation. Stepped holes are used to ensure orifice type flow rather than tube type flow through the retainer; thus, the vena contracta is established externally rather than inside the retainer itself. Rating: 150# - 2500#.
Pressure Rating: PN10, PN16, PN25, PN40, CL150, CL300, JIS10K, JIS 20K. Motion for highly accurate positioning and. Ball valves are designed to be used in a variety of applications and markets, but a V-port ball valve offers the added ability to be used as a control valve where necessary. 5% as measured by the Benchmark Control Valve Diagnostics™ System.
