Floating Ball Valve
SS Double Floating Pneumatic Actuated Ball Valve
Features & Benefits
1. Fully captured spiral-wound graphite filled body gasket on split body designs.
2. Locking lever or gear operator standard.
3. Blowout-proof stem
4. Full and standard port available
5. Low Emissions: API 622 certified graphite-based packing for fire-safe designs.
6. PTFE stem seal as well as dual packing configurations are available.
7. Integral ISO mounting pad on cast valves for ease of automation without bracket or separate coupler.
8. Internal and external stem bearings to prevent “side loads” that can cause leakage in the field.
SW Super Duplex Ball Valve
Features & Benefits
1. A patent-pending seat design provides automatic cavity relief without requiring a vented ball or external relief valve. API Spec 6D monogram is available upon request.
2. A variety of actuator types, including pneumatic, hydraulic, diaphragm, vane, electromechanical, and electrohydraulic, can be easily installed.
3. The inline valve stem packing options consist of PTFE or graphite. The packing is field adjustable and virtually never requires lubrication.
4. Didtek Ball Valves cana be supplied and certified to meet the requirements of fugitive emissions (FE) as regulated by ISO and API.
5. The stem is positively retained and cannot be removed with the valve in service.
Corrosion Resistant PEEK 317 Ball Valve
Features & Benefits
1. Didtek Ball Valve Stem head design provides mounting of the lever handle always in parallel to the flow passage. Misalignment of the handle is thus prevented.
2. The lower end of the stem is designed with an integral collar to be blowout-proof. It also functions as the backseat for assured stem sealing.
3. An antistatic feature is provided to ensure electrical continuity between ball, stem, and body.
4. Facility for mounting a locking device for prevention of accidental valve operation is provided.
5. Plant fires are a serious concern for soft-seated ball valves because of possible fluid leakage and consequent increase of the fire magnitude caused by deterioration of resilient sealing materials.
6. Didtek ball valves are engineered for fires safety and successfully fire tested to minimize both external and internal fluid leakage after plant fires.
ATEX Electric Actuated Motor Ball Valve
Features & Benefits
1. Didtek Ball Valve can be quickly opened and closed with a quarter turn movement
2. Ensure a very tight seal without the need for high torque forces
3. have a compact design (this is the main difference between a ball valve and a gate valve – which are both on/off devices).
4. In a floating valve, the ball is suspended in the flowing fluid and is kept in position by the compression of two elastomeric seats against it.
5. Plant fires are a serious concern for soft-seated ball valves because of possible fluid leakage and consequent increase of the fire magnitude caused by deterioration of resilient sealing materials.
6. The “Full port” (FB) type features a bore size (the hole of the ball) matching the bore size of the connected piping. Full port ball valves minimize the pressure drop that is generated by reduced port valves but they are of course more bulky, heavy and expensive. FB ball valves are better suited, than RB ball valves, for throttling applications.
Automation Electric Motor Operator DBB Ball Valve
Features & Benefits
1. This safe and efficient operation single piece floating ball valve is non-directional and can be installed in either end of the pipeline.
2. This floating ball valve is designed and manufactured with ASME/API, ISO and JIS standards and can be made of stainless steel and carbon steel materials.
3. The 2-piece flanged end floating ball valve from Kinvalve is available in stainless steel and carbon steel bodies.
4. Available in sizes form 1/2″ – 12″, they come with an ISO 5211 mounting pad for automatic actuation.
5. Meeting all Class requirements, this ball valve is relatively affordable and offers excellent versatility in application.
6. Didtek’s full-port design, flanged end 3-piece floating ball valves are ideal for the safest inline maintenance.
7. The valves come with a blowout-proof stem design.
High Heat Temperature Pressure Metal To Metal Ball Valve
Features & Benefits
1. Employing the latest in processing technology and manufacturing automation, Chaoda offers high quality metal seated ball valves for service conditions where soft seats will simply not perform. Whether it is temperature or abrasion driven, Chaoda offers a broad range of hard coatings designed for optimal performance.
2. Minimal moving parts with flawless execution make our floating ball valves a more suitable choice for severe applications. Full rotational surface lapping of slurry resistant scraper seats makes our metal seat ball valves the most dependable sealing valves available – at an unparalleled price point.
3. In a floating ball valve, the seats hold the ball in place and it floats around in the valve body. Upstream pressure from liquid or gas pushes the ball up against the downstream seat. This helps form a leak tight seal.
1. Compact design
2. Cost-effectiveness
3. Customizable
4. Little flow resistance
5. Reliable sealing functions
6. Uncomplicated construction
How Do Floating Ball Valves Work?
Floating ball valves are operated by a shaft, or stem, attached to the top of the ball that turns it 90 degrees (a quarter turn). As the ball rotates, the port is covered or uncovered by the wall of the valve body, either releasing or halting the flow of media. The stem is attached loosely enough to the ball that, as the ball rotates on its axis, the pressure of the flow pushes the ball against its downstream seat, creating a tight seal.
What Is A Floating Ball Valve?
As the most common valve type in the piping industry, floating ball valves play an important role in regulating flow through pipelines and other piping systems in the gas, oil, water and other industries. They create a bi-directional seal, and can even be customized for high pressure operations, though normally they are only used in pipelines with low to medium pressure.
What Is A Floating Ball Valve Used For?
Floating ball valves provide an air-tight seal when completely closed, so offer a variety of industries a key method for regulating flow of liquids such as oil, natural gas, steam and water.
