Overview Details for D/DA

Fisher™ D & 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 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.

Massive guiding 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.
Screwed bonnet/body joint allows repair or maintenance with a minimum of tools.
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.
Valve body and end connection constructions are available for API; as well as ASME standards.
NACE trim and bolting materials are standard for all applications. These materials comply with the requirements of NACE MR0175-2002.
