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.
FEATURES
1.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.
2.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. 3.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.
