Design D and DA Control Valves

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 ANSI standards.
NACE Trim Standard — NACE trim and bolting materials are standard for all applications.
These constructions comply with the recommendations of the National Association of Corrosion Engineers
