Plast-O-Matic Series CARD Combination Air Release & Degassing Valve
Plast-O-Matic Series CARD Combination Air Release & Degassing Valve
Features
- • Combines three functional valves within one valve enclosure: air release, continuous degassing and vacuum relief.
- • Air release function automatically releases trapped air during system start-up.
- • Degassing function provides continuous removal of accumulated air or gas during operation.
- • Vacuum relief function helps prevent pipeline vacuum conditions in case of leaks or siphoning.
- • Cost-effective design can replace the need for three separate venting valves.
- • Self-guided, high-buoyancy float with elastomeric sealed poppet provides dependable, leak-tight sealing with minimal process-fluid emissions.
- • Poppet design provides reliable sealing compared with conventional ball-type seats that may deform under load.
- • High-buoyancy float allows the valve to close tightly after air has been expelled while helping prevent liquid escape.
- • Thermoplastic and elastomer construction provides corrosion resistance for chemical applications.
- • No metal parts in the valve.
Description
The Plast-O-Matic Series CARD Combination Air Release and Degassing Valve combines air release, continuous degassing and vacuum relief functions within a single valve assembly. This multifunction design provides an efficient solution for managing trapped air, accumulated gases and vacuum conditions in piping systems.
During system start-up, the air release function allows unwanted air to escape from the pipeline. During normal operation, the degassing function continuously removes accumulated air or gas that may affect system performance. The vacuum relief function allows air into the piping system when negative pressure occurs, helping protect pipelines and equipment against vacuum conditions caused by leaks or siphoning.
The Series CARD uses a self-guided, high-buoyancy float together with an elastomeric sealed poppet to provide reliable sealing while minimising the escape of process fluid. Its thermoplastic construction contains no metal parts and provides corrosion resistance for chemical processing, water treatment and other demanding fluid-handling applications.
