The ASCO? Series 641/6422/643 aluminum filter regulators maximize process efficiency by providing high flow rates and precise pressure regulation to downstream instruments. Robust media filtration prevents downstream process contamination, enhancing safety and reliability. The rugged, aluminum construction with specialized coating will stand up to harsh process environments.
Series 641/642/643 Series Aluminum Filter Regulator Features:
- High flow particulate filter regulators suitable for harsh process applications
- Robust metal construction of both internal and external components provides reliable service in harsh, corrosive environments
- Broad range of options including low-temperature and low-copper variants, as well as manual and automatic draining features
- Quick relief available, enhances safety by allowing downstream pressure in the actuator or other equipment to exhaust if supply pressure is lost
- Regulating adjustment with Screw / T-handle
- Built-in overpressure relieving function, non-relieving option available
- ATEX, Option: II 2G Ex h IIC T5 Gb / II 2D Ex h IIIC T100° C Db
- Optional CRN (Canadian Registration Number) certificate and UKCA (UK Conformity Assessed) certificates available
