Product Overview

VFA valves sit between the station flanges as a wafer element, so they take almost no face-to-face length. That makes them a practical isolation point at regulator inlets and outlets, at filter bodies and on meter runs where space is tight.

Key Features

• Wafer flangeless design, DN50 to DN250, PN16 or ANSI CL150

• Maximum operating inlet pressure 16 bar PN16, 19 bar CL150

• Steel body, pressed steel disc, stainless steel shaft

• Replaceable NBR soft seat, FKM available on request, hermetic shutoff

• Lever VFA, gear VFA-MR and odorization VFA-MRO versions

Typical Applications

Isolation upstream and downstream of station regulators, filter and meter bypass lines, industrial and commercial gas supply headers, and low temperature service down to -20 C with the low temperature version.

Selection Guide

Size the valve on line velocity rather than flange size, and confirm the flange standard matches the mating pipe flanges since the wafer body relies on them for alignment. Use VFA-MR gear operation above DN150, and VFA-MRO where an odorization injection point is required.
