1 D and DA control ValvesFisher D and DA single port, high pressure Valves arewidely used in oil and gas production industries. Thesevalves are especially useful for either throttling oron/off control of liquids or gases which are gritty,sticky, or which have a tendency to build up on internalvalve parts. The DA valve is also useful in angle pipingor other applications where a self draining valve otherwise noted, all NACE references are toNACE MR0175 Heavy Duty Construction Massive guiding (figure1) positively aligns the valve plug in the seat ring forhigh pressure drop applications. The screwed inseat ring completely encloses the seat ring Easy Maintenance Screwed bonnet/body jointallows repair or maintenance with a minimum Severe Service Capability Valve is available withVTC (ceramic) trim for service in very erosiveapplications. The valve plug is also available with atungsten carbide tip and the seat ring can be fittedwith a full bore tungsten carbide insert for Meets Variety of Specifications Valve body and endconnection constructions are available for API aswell as ASME 1 Fisher D Valve with 657 Actuatorn NACE Trim Standard NACE trim and boltingmaterials are standard for all applications.
