Fisher™ V270 Full-Bore Ball Control Valve

The Fisher V270 is a three piece, trunnion mounted,
full-bore control valve designed from the ground up
with features for optimized pressure, flow and process
control.

The V270 full-bore ball valve is designed for
automated control in bypass, batch, monitor, and
emergency shutoff service applications, and it
presents little or no restriction to flow.

The V270 full-bore ball valve is available with
composition seals, and process type live-loaded shaft
packing for improved service life and lower emissions.

Unless otherwise noted, all NACE references are to
NACE MR0175/ ISO 15156.

Features

n Excellent Flow Control—Shaft and trunnion guiding

provides improved dynamic control.

n Sour Service and Sour Crude Oil Capability—

Standard construction materials comply with NACE
Standard MR0175 / ISO 15156.

n Tight Shutoff—Self-adjusting seals that are pressure

assisted provide Class VI shutoff for long reliable
service. The design incorporates a heavy duty
S31600 stainless steel carrier that retains the
composition seal.

n Free Standing Design—Comes standard with a base

bracket allowing the valve to sit upright.
