NEW BRITAIN, CT, February 12, 2010 – Peter Paul Electronics, Co., Inc, explains why in rugged, dirty, corrosive application one is better served by a plastic valve with an encapsulated coil over a metal valve. The points of differentiation follow:
- The initial cost savings of a plastic valve over metal is obvious, but additional cost savings are incurred with lower costs to install, reduced freight, maintenance costs and a longer service life of the valves. Plastic valves, on average, out-perform metal valves and have maintenance free service.
- Installation is easier due to lighter weight of ½ to 1/3 of metal which in turn reduces material handling of labor, freight and installation costs.
- A plastic valve can handle high temperatures or has low thermal conductivity and corrosive chemicals. The coil encapsulation technique is used to segregate the winding from the outside world and receives the hazardous location ratings. The “high end engineering grade polymer” used for the “Encapsulated Type Coils”, is a polyamide, a very tough material that is glass reinforced. This polymer is perfect for high heat applications with a UL Class H 180°C rating. It can withstand severe thermal Cycling without cracking.
- Plastic valves can be regarded as “greener” because of the lower amount of energy it takes to produce than a metal valve.
- The interior lining of a plastic valve is very smooth creating a high flow coefficient that will not rust, corrode or pit like metal. Resulting in an even flow rates over time.
- The conduit Boss is made of Stainless Steel with an electrolysis nickel coating, making it very durable. These units are therefore comparable to the Potted, Stainless Steel version of the legacy counterpart.
