AIL Cast Steel Angle Globe Valves are tight sealing, easy-to-operate regulation valves for liquid and gaseous fluids over a wide range of line pressures and temperatures.
Angle Globe Valves operate in a manner similar to that of a globe valve. However, the 900 angle between the inlet and outlet pipes greatly reduces the pressure drop across the valve as compared to a conventional globe valve. These valves are used for flow control especially in systems where valve geometry or pressure drop is a concern.
The flow to the body outlet is streamlined by the smooth curvature of the inner surface which minimises the pressure drop across the flow path. The bonnet is fitted with a bonnet bush to guide the stem and provide for back seating when the valve is open and under pressure.
The disc provides a fine bearing on a taper seal for tight sealing over a wide range of differential. pressures. As the seating between disc and body seat ring is a narrow line contact, tight sealing can be achieved even if any foreign particle gets stuck to the seating area. The disc and stem are held together by a disc nut with allowance for the disc to swivel. The disc has internal threads to receive the disc nut which retains the stem with the disc. A stem thrust plate is provided between the stem and the disc.
A forged shoulder type body seat ring has threaded engagement with the body and a widetapered seating area. The body seat ring is tack welded to the body to prevent loosening. The seating surfaces are ground and lapped.
