Thermoplastic valves made of materials such as Polyvinyl chloride (PVC), Acrylonitrile-Butadiene-Styrene (ABS), Glass Fibre Polypropylene (GRPP), Anti-Static Polypropylene (ASPP), and Polyvinylidene fluoride (PVDF) are becoming the material of choice for more and more chemical process applications. These valves are used in industrial and commercial applications due to reasons such as chemical resistance; high purity standards; abrasion resistance; lighter weight; lower cost; and ease of installation.
Careful actuator selection is required when plastic valves are specified. While the mechanics in applying pneumatic actuators to plastic quarter-turn valves is no different than metallic valves.
The rotary vane actuators manufactured by Kinetrol meet these requirements as standard. Engineered specifically for high-cycle, dirty, and corrosive applications, these very hardy, compact actuators come with an epoxy stove enamel finish, stainless steel internal and external hardware, with spring units that are totally sealed from the atmospheric contaminants. For applications requiring greater corrosion resistance, such as caustic wash-down or salt-laden environments, an optional Blueline coating can be applied.
