PRODUCT TITLE:
DUAL-FUNCTION COMPOSITE EXHAUST VALVE (CARX SERIES)
Product Overview & Applications
Advanced Air/Gas Management for Fluid Systems
- Purpose: A multi-functional valve designed to automatically exhaust air/gas during system filling and intake air during pipeline draining, preventing vacuum damage. Ideal for balancing pressure in fluid networks.
- Key Applications:
- Water Supply Systems: Pump stations, reservoirs, irrigation pipelines.
- Fire Protection: Sprinkler systems, fire hydrant networks.
- Industrial Processes: Cooling loops, boiler feeds, chemical transfer lines.
- Building Services: HVAC chillers, condensate removal in air conditioning.
