Selection Guide

What to Confirm for Plug Valves

For plug valves, review plug design, port arrangement, lubrication/sleeve, material, end connection and operating method. The final selection should match the piping class, service conditions and project specification.

Typical Applications

Where Plug Valves Are Used

Oil and gas, refinery, metering, transfer, chemical and wastewater systems. Confirm fluid, pressure, temperature, cycling frequency and shutoff requirements before quotation.
