Jamesbury 4-inch CL-150 Wafer-Sphere Butterfly Valve 815W-11-3600XZ-C with Pneumatic Actuator

The Jamesbury 815W-11-3600XZ-C is a high-performance wafer-style butterfly valve designed for demanding industrial applications, featuring a 4-inch nominal size and Class 150 pressure rating. Constructed from 316 stainless steel (316SS) for the body and disc, it offers excellent corrosion resistance and durability in harsh environments such as chemical processing, pharmaceuticals, and food/beverage industries. The valve incorporates Jamesbury's patented Wafer-Sphere design, which provides bubble-tight shutoff, low torque operation, and extended service life compared to traditional butterfly valves. It includes an Xtreme seat material for enhanced temperature and chemical resistance. This assembly comes equipped with a Jamesbury VPVL series pneumatic actuator (model VPVL350SR6BD), providing reliable automated control with spring-return functionality for fail-safe operation. Additional components include a Quartz limit switch for position monitoring and an ASCO solenoid valve for pneumatic control. Benefits include reduced maintenance costs, high flow capacity (Cv up to 550), and compatibility with ANSI flanges. Drawbacks may include higher initial cost versus standard valves and the need for compressed air supply for actuation. Ideal for on/off and throttling services in pipelines handling corrosive fluids, gases, or slurries, offering superior performance over competitors like Keystone or Bray in terms of seat longevity and torque efficiency.
