ARCA steam-conditioning valves are customized in line with your specific operating conditions. A wide range of designs and materials – from cast globe-style housings to forged angle-style valves – are available to meet all pressure and temperature requirements.
ARCA control valves optimize efficiency and enable cost-effective operation in small plants and large-scale power-generation facilities. ARCA steam-conditioning valves integrate sound-reduction measures such as perforated plugs and seat rings with graduated control to minimize the impact of sound emissions on humans and the environment. We can even dimension a silencer system that encompasses the condenser of your plant.
OUR INNOVATION |
HOW YOU BENEFIT |
1. Modular system with standardized components |
· All nominal diameters · Fewer components · Only one special tool required |
2. Flow-optimized housings |
· Low noise emission · Optimized KV values for all nominal · diameters |
3. Optimized trim comprising plug and seat for all application areas |
· Adaptable to any requirements · High control accuracy · Wide control range · Low noise emission |
4. Standardized interface to valve actuator |
· All types of actuator can be used - pneumatic, electric, and hydraulic · Can be easily reconfigured later on |
5. Value trims can be completely removed |
· Maintenance work is fast and simple · All internal parts can be removed · No special machines required · All interior components are clamped or screwed (no welding) |
