The Different Types of PVDF Ball Valves
PVDF (polyvinylidene fluoride) is a thermoplastic polymer that is highly non-reactive. It's a high-purity technical plastic that's resistant to acids, solvents, and hydrocarbons, and it's employed in a variety of industries and applications. Chemical processing, healthcare and pharmaceutics, biomedical research, ultra-pure applications, nuclear waste handling, petrochemical, and wastewater management are just a few of the applications. The construction and operation of these PVDF Ball valves differ to a lesser extent. The following are the most common valve types:
BallValves
One of the most common forms of control valves is the ball valve. These valves use a hollow ported ball spun by external handles to control flow. When the holes in the hollow ball align with the flow of the fluid, the medium flows through the valve, and when the solid section of the valve aligns with the flow, the medium stops flowing. Quarter-turn valves are ball valves. A quarter-turn valve requires the handle to be twisted 90 degrees to open or close the valve. Ball valves feature a straightforward and adaptable design and long service life. They can be utilized without needing repairs after multiple cycles if properly controlled (actuation). Valves can handle fluid pressures of up to 15,000 psi and temperatures of up to 752 degrees Fahrenheit, depending on the type and arrangement. Depending on the type of valve used, the body is also available in several construction materials.
A butterfly valve is a type of valve.
As the ball valve, the butterfly valve is a fast-acting valve that opens and closes using a quarter-turn mechanism. On the other hand, Butterfly valves control flow with a round disc affixed to a central rod in a design that resembles a stylized butterfly, hence the name. The fluid flow is stopped once the disc is spun and its cross-section is perpendicular to the flow route. When the disc is spun backwards, it is parallel to the fluid flow, allowing the fluid to flow freely. The disc can also be spun gradually to control the flow rate. The actuation of butterfly valves can be done in a variety of ways. In some areas, such as the petroleum industry, butterfly valves are more common than ball valves. Butterfly valves are less expensive to run and install than other valves.
Valvesin the shape of a globe
Straight flow, angle flow, cross-flow, and Y flow globevalves are some of the different types of globe valves that can be utilizedbased on the flow pattern. These valves are activated linearly. A disc element travels linearly in the upward direction proportional to the fluid flow through the valve as the handwheel is rotated to the open position. Because of the number of revolutions the fluid travels through the valve, there is energy loss and pressure drop in the valve. They are also extremely difficult to operate.
Needlevalves are a type of needle valve.
Needle valves feature a needle-shaped plunger implanted tocontrol the flow with a conical end known as the needle. They're employed inpipelines that transport extremely pure liquids and gases, like as propane. Though the needle valve can be used to turn on and off, it is best utilized to control the flow rate of fluid going through the pipe (especially in pipes with lower flow rates).
About Petron Thermoplast
We have a PVDF ballvalve series called the Dual Block Series. A Dual Block 2-Way Ball Valveuses two seating surfaces to lock off pressure from both ends of a PVDF DualBlock 2 – Way Ball Valve. Depending on your process and demands and industrial water application requirements, you can choose from a range of setups. When selecting a valve, the fluid properties, pressure, and temperature must be considered. On the other hand, the valve's intended function may be the most important aspect.
