SH25S News | Fits everywhere!
These separators are composed by an inlet plate with a propeller blade design which promotes high speed centrifugal motion and allows removal of up to 99% of water droplets and solid entrained particles from the medium. The unit has no moving parts and does not require any maintenance. It’s one of the simplest ways to improve steam quality and heat transfer efficiency on your steam system, in main lines or at the point of use.
MAIN FEATURES
Sizes: 1/2” to 6”; DN 15 to DN 150
Material: Carbon steel
Connections: Flanged EN 1092-1 PN 16 or PN 40 / Flanged ASME B16.5 Class 150 or 300

The new TDS blowdown control valve
When a steam boiler is in operation there is continuous evaporation of boiler water wich causes an undesirable increase in TDS (Total Dissolved Solids) concentration. A typical problem that results from this is water foaming, which leads to reduce boiler performance and wet steam. Furthermore, dissolved and suspended solids will carry over into the steam lines, contaminating valves, tubes, heat exchangers and steam traps, leading to corrosion, scaling and erosion. For these reasons, a certaing amount of boiler water must be discharged continuously or periodically to ensure TDS concentration is kept within the recommended parameters.
The ADCATrol VPC26 is a control valve specially designed for this purpose and features a multi-stage trim to progressively reduce the energy of the fluid. This makes it ideal for discharge of boiler blowdown at high differential pressures where flashing is a concern.
The valve is suitable for both continuous and on/off TDS control via a PA series reverse action pneumatic actuator or AV saeries fail-safe spring return actuator.

The new automatic pump trap: PPT14
The equipment combines the features of a float steam trap and a pressure operated pump, in one single unit. Whenever the steam trap function is incapable of draining condensate, the pump function is activated (using external steam pressure).
The pump replaces the necessary positive pressure to lift the condensate to the return system, before water logging occurs, avoiding water hammer and consequent noise, equipment damage, corrosion, unstable temperature control, etc.
MAIN FEATURES
- Compact design
- No electric requirements
- No NPSH issues
- Operation under vacuum conditions
- No motive or flash steam is lost
- Low filling head for minimal installation space requirements
