Butterfly Valve Buying Guide

Butterfly valves are critical for managing fluid flow in various systems. Selecting the right valve can greatly impact system efficiency.

Consider the following when choosing a butterfly valve:

  • Identify the maximum operating pressure and temperature to ensure the valve's material and design can handle the requirements.
  • Determine the type of connection needed, such as wafer, lug, or flanged, based on installation needs and system compatibility.
  • Assess the required sealing performance and select between resilient-seated or metal-seated valves accordingly.
  • Evaluate the fluid characteristics, including chemical composition and viscosity, to choose appropriate materials and coatings for durability.

Frequently Asked Questions

What are the common types of butterfly valves?
