Pressure Reducing

Conventional method for pressure reducing & desuperheating of steam calls for pressure reducing valve followed with desuperheater.
Forbes Marshall Arca brings the most advanced method to reduce pressure & temperature of steam in a single unit called "Combined PRDS". During the process of pressure reduction in the valve water is being injected simultaneously into a highly turbulent zone called the "Vena Contract" zone. This causes instantaneous evaportation of water for complete desuperheating.

Control Valve

For over five decades Forbes Marshall has manufactured & provided advanced quality instrumentation products for various industries such as Power, Oil & Gas, Food & Beverages, Pharmaceuticals, Pulp & Paper, Chemicals & HVAC.

Forbes Marshall valves are modular in design & versatile in construction. They are designed and manufactured using advanced CNC machinery thus making them virtually trouble free to operate with minimum maintenance. Coupled with single spring and multi spring diaphragm actuators, control valve series 100, 140 and 160 provide complete control solutions to most critical service conditions.

Desuperheating

Forbes Marshall Arca, ranks amongst the world's leading suppliers of steam desuperheaters. Specializing in designing and manufacturing such equipment for power, process and co-generation plants.

Steam Desuperheatering:

The most practical way of reducing the superheat valve of steam is by the direct addition of water. To achieve temperature stability of the conditioned steam and prevent thermal shock in downstream pipes, the cooling water must be atomized. It is also necessary to have a correct mix of superheated steam and cooling water.
