What are High-Performance Butterfly Valves?

A double offset butterfly valve is an HPBFV rated for ANSI (285 @ 100F or 100 psig @ 400F for 150# ANSI) rated applications. For this type of valve, the disc and stem are double offset, (set back behind the disc and to the side) causing the disc to rotate into place upon closure without significant seat contact. Different from an RSBFV, the stem is located behind the disc, which enables the disc to “rub” over the seat in the last 10% of travel, during the 90-degree rotation.

This seat usually is some type of Reinforced Teflon or for high temperatures above 450F, the seat can be metal, usually a hardened metal, like Stellite. The most user-friendly allow removal/replacement of the stem, disc, and seat without welding

A HPBFV is a reliable valve for handling high temperature and high-pressure situations, and when superior adjustable stem packing is needed to control stem leakage or emissions. These are for temperatures of up to 1200 degrees F and pressures of up to 1440 psig(150-600# ANSI).

 

Applications:

 

Double offset butterfly valves are best used for:

  • Oil and gas
  • Pulp and paper
  • Power generation
  • HVAC
  • Chemical
  • Shipbuilding
  • Water/wastewater treatment

The valves are used for higher pressure than zero offset butterfly valves (ANSI Rated), and offer adjustable packing on the stem thus lower emissions and stem leakage.
