Purpose and Features of PVC Valves
Posted: Apr 18, 2016
Over the years, PVC (polyvinyl chloride) valves have infiltrated both domestic and commercial niches. PVC valves composed with proper additives that offer the required chemical and physical compatibility. Though they’ve restricted utilization in high temperature applications, improvements in PVC technology have allowed making of the valves with genuine forbearance to medium range heats.
Purpose of PVC valves:
One most common reason for the collapse of traditional metal-based valve is decomposition. Decomposition affects industries like nuclear power creation, chemical processing, onshore & offshore oil & gas, water treatment, underground pipeline, highway maintenance and a lot more. Moreover, choices for a preventive action are restricted. The pervasive character of decay in certain ventures forced them to seek alternative choice, such as PVC valves as they were practically unaffected by acidic surroundings. In addition, flat surfaces are defiant to scaling and permit superior flow rates, whereas outer surfaces need no supplementary coating to safeguard the shell from ecological injury. PVC ball valves turn away any natural growth, making it appropriate for refined applications like semiconductor fabrication & manufacturing of polymers. Such features made it enviable to most of the industries.
Features of PVC valves:
As mentioned earlier, PVC valves provide non-corrosive, non-polluting, and gentle surface for processing fluids. Besides these attributes, they’re light in weight in comparison to mental valves of identical dimensions. They provide resistance to acid alongside decay and they resist any development of scale over the surface due to their softness. In comparison to metal valves, assimilation with plastic pipes & fixtures are effortless with PVC valves and fittings.
According to the life span evaluation of PVC custom-made by the European Commission, the standard lifespan of PVC water pipes varies anywhere amid 40 & 80 years and thus a conformist estimation of the PVC valves' life span is close to 10 to 20 years. This compares positively to other options due to their usage of lesser non-renewable supplies, i.e. 57 percent of PVC is resultant from salt & the remaining 43 percent is acquired from oil & gas. Most PVC valves can manage pressure of about 150 lbs/sq.in, which is lower for most piping sizes in the schedule 80 threaded piping systems.
Because of the existence of more than 50% chlorine in the PVC, PVC valves are fire-defiant. Even when the valves are burned, they release hydrogen chloride gas that stops oxygen from reaching the surface and thus prevents quicker reaction. The valves present outstanding chemical compatibility with salts, alkalis, oxidizing agents, and acids. In addition, they offer reasonable compatibility with natural solvents. Since PVC has simple processing character, the preferred measurement for the valves can be accomplished.
