PVDF (polyvinylidene fluoride) butterfly valve is a kind of valve made of PVDF material, which is mainly used for controlling the flow of corrosive medium.PVDF is a kind of high-performance fluoroplastic with excellent chemical resistance, high temperature resistance, UV resistance and mechanical strength, which is suitable for chemical, pharmaceutical, water treatment, electronic and other industries.
Strong corrosion resistance: PVDF materials have excellent chemical stability, good tolerance to most acids, alkalis, salts and other chemical substances, can resist the erosion of a variety of corrosive media, and are suitable for conveying corrosive liquids and gases.
Good high temperature resistance: It can be used for a long time at high temperatures, generally can withstand temperatures of about 100°C, and some specially formulated PPH materials can withstand higher temperatures and meet the needs of some high-temperature processes.
High mechanical strength: It has high tensile strength and impact resistance, can withstand certain pressure and external force impact, is not easy to break or damage, and ensures the safety and stability of the pipeline system.
Sanitary and non-toxic: PPH materials meet food hygiene standards, are non-toxic and harmless, and will not pollute the transported substances. They can be used in industries with strict hygiene requirements such as food, beverages, and pharmaceuticals.
Light weight: With low density, PVDF pipes, pipe fittings and valves are much lighter than metal pipes, which are easy to carry, install and maintain, and can reduce construction difficulty and cost.
Good insulation performance: It has good electrical insulation performance and can be used in electrical and electronic fields to prevent problems such as current leakage and short circuit.
Long service life: Under normal use conditions, PVDF pipes, fittings and valves have a long service life, which can reduce the frequency of replacement and repair and reduce long-term costs.
Butterfly valves are used in a variety of piping systems to regulate the flow of liquid or gas between two points.They provide efficient and reliable operation by allowing for quick on/off control, as well as precise regulation when necessary.
These valves are typically installed in pipelines that receive frequent use and must be trusted for reliable performance. Wafer butterfly valves consist of a disc mounted on the end of a stem connected to an actuator such as a hand wheel or motor.
When the valve is opened, the disc swings away from the line, creating an unrestricted path for the flow through the middle of the valve. When closed, the disc's edges come into contact with either side of the line, blocking it off completely. This design helps to ensure tight shut-off without having to install any additional seals or packing materials. The ease of installation and simple design make wafer butterfly valves a popular choice for many applications, providing cost savings over other control valves due to their shorter installation time and low maintenance requirements.
