Fisher D & DA High Pressure Globe Valve – Sliding Stem Valves

Fisher D & DA High Pressure Globe Valve with single port is part of the sliding stem valve that are are used in oil and gas production industries 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.

The Fisher D & DA body and end connection constructions are available for API as well as ASME standards. Trim and bolting materials are available for applications handling sour fluids and gases.

Product Features

Heavy-Duty Construction—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.
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.
NACE Trim Standard—NACE trim and bolting materials are standard for all applications. These materials comply with the requirements of NACE MR0175-2002
