Key features/benefits
This type Globe Valves are used for regulating and throttling at various pressures or flow rates and they can provide pressure and flow control as it can operate in semi-open positions. Control valves have a cage. It is a cylinder that is drilled and tightened between body and bonnet. Shape of the cage holes provide to control of pressure drop and noise.
Control Valves can be produced as balanced or unbalanced type. Balance is provided by holes on the disc. Vastas recommend unbalance type for 1” and 1 ½”.
Globe Type Control Valves are produced with steel body and API Trim No. 8 as standard, ends being flanged to ASME B16.5 or Buttwelding to ASME B16.25 and Face to Face Dimensions complying with ASME B16.10 standard. Mating Flanges (WN), Fasteners (2H & B7) and Gaskets (SWG) are supplied upon request. Vastas gaskets for sealing of flanged connections are made of non-asbestos materials and are fireproof even for 150 class, spiral wounded 316SS & Graphite or RJ type for higher classes.
