Fisherr D and DA Control Valves

Fisher D and DA single-port, high-pressure valves are
widely used in oil and gas production industries. These
valves are especially useful for either throttling or
on/off control of liquids or gases which are gritty,
sticky, or which have a tendency to build up on internal
valve parts. The DA valve is also useful in angle piping
or other applications where a self-draining valve is
desired.

Unless otherwise noted, all NACE references are to
NACE MR0175-2002.

Features

 Heavy-Duty Construction–Massive guiding (figure

1) positively aligns the valve plug in the seat ring for
high pressure drop applications. The screwed-in
seat ring completely encloses the seat ring gasket.

 Easy Maintenance–Screwed bonnet/body joint

allows repair or maintenance with a minimum of
tools.

 Severe Service Capability–Valve is available with

VTC (ceramic) trim for service in very erosive
applications. The valve plug is also available with a
tungsten carbide tip and the seat ring can be fitted
with a full-bore tungsten carbide insert for erosive
service.

 Meets Variety of Specifications–Valve body and end

connection constructions are available for API as
well as ASME standards.

Fisher D Valve with 657 Actuator

 NACE Trim Standard–NACE trim and bolting

materials are standard for all applications. These
materials comply with the requirements of NACE
MR0175-2002.
