A 150 PSI butterfly valve is a lightweight, low-pressure quarter-turn rotary valve engineered to provide dependable flow regulation and tight isolation in piping networks rated up to 150 PSI (Class 150 LB / PN10-PN16 working pressure). It features an internal disc that rotates 90 degrees within the stream, compressing against a resilient elastomeric seat (such as EPDM or Viton) to deliver a bubble-tight seal with minimal operating torque. Its compact wafer, lug, or flanged profile requires negligible mounting space and drastically lowers structural support weight compared to traditional gate or globe designs. Procurement networks and mechanical contractors can lower pipeline layout costs and simplify installation logistics by importing premium 150 PSI butterfly valves directly from certified manufacturers in China through our B2B commercial platform.
