NELES SERIES GM CONTROL VALVES GLOBE-OMEGA, MULTI-PATH & MULTI-STAGE TRIM

Metso's series GM, Omega trim valves are most suitable for high pressure drop applications of both compressible and uncompressible fluids as it enables the flow velocity to be controlled through the multistage Omega trim. Also, series GM range of valves combines high integrity features, such as 2 or 3 dimensional flow path multistage trim, a high flow capacity and a wide range of 'OMEGA' trim designs. This means it is ideally suited to meet the various severe service process control requirements that are demanded from a wide range of industry related applications. The 'OMEGA' trim design is a multipassage, multiturn disk stack trim. There are 2~32 turns designs available depending on pressure drop and potential for cavitation. The fluid passes through the flow passage generated by the Omega multistage trim. The pressure drop is staged across the stacks so that the pressure drop progressively reduces as it passes through the steps of the trim. This gives excellent resistance to cavitation on high pressure drop applications. For very high pressure drop applications the Omega trim, plug and seat insert would be standard manufactured from hardened stainless steel, stellite stainless steel, and optionally solid tungsten carbide or glass metallic. Standard valves are equipped with VD spring diaphragm actuators or VC Cylinder actuators with ND9000® intelligent valve controllers for precise flow control, extended operational life and performance monitoring on-line
