GLobe-Cage Balanced Control Valve

Model Number

Series 4000

The series 4000 heavy duty cage guided balance valves indeally suited to high pressure drop compressible and uncompressible fluids as it enables the flow velocity to be controlled through the valve by the incorporation of an increased outlet and pressure drop elements in the outlet end.
Also, series 4000 range of valves combines high integrity features, such as ASME VIII body & bonnet bolting design, a high flow capacity and a wide range of trim designs. This means it is ideally suited to meet the various critical service process control requirements that are demanded from a wide range of industry related applications.

Performance

• Low-noise, anti-cavitation control and erosion resistant trims
• Streamline flow passages to secure capacity

Design Application Flexibility

• Various construction design available with a range of different end dtyles and connections
• Large variation of trim designs from single stage multi-hole cage to multi-stage low noise, anti-cavitation trim designs
• Wide range of applicable noise control components, silencers, baffle plates
• Inherently characterized trim offered in Equal Percentage, Modified %, Linear, and Semi Throttle
• All trim components removable from the top side for easy of maintenance
• Large range of CVs per body size allowing for wide applicable in process conditions
• Clamped cage for heavy duty guiding on severe service applications
• High integrity cage guiding system
• low emission packings available

Tendril(Multi-hole, Multi-stage) Trim
The trim design presented a multi-stage, multi-hole trim. There are 1~5 stage designs available depending on pressure drop and potential for cavitation. The fluid passes through the flow path generated by incorporating angled flats onto the surface of the plug, together with a cut out on the internal diameter of the seat. The pressure drop is apportioned across the stages of letdown so that the pressure drop progressively reduces as it passes through the stages of the trim. This gives excellent resistance to cavitation on high pressure drop applications. For very high pressure drop applications the plug and seat insert would be standard manufactured from hardened stainless steel, stellited stainless steel, and tungsten carbide or glass metallic optionally.
