An explosion occurs if a flamable gas/dust-air mixture gets in touch with oxygen and ignition source. RICO Sicherheitstechnik AG developes and designes since years efficient solutions to protect plants, employees and the environment from explosion damage. Those explosion decoupling actions have proven to be successful worldwide.
Functional principle VENTEX® ESI-P
The plant is equipped with sensors for pressure and flames. The system control sends a signal to activate the gas generator. The generated pressure moves the valve poppet in milliseconds to the gasket. The closed position of the poppet denies efficiently the propagation of flames and shock waves. The medium inside the pipes usually flows around the poppet in open position. When the poppet is in open position, it can be open and closed pneumatically.
Field of application
The explosion isolation valve VENTEX® ESI-P is installed within applications, where explosive metal dust, gas or hybrid mixtures occur:
- Pharmaceutical industry
- Chemical- / petrochemical industry
- Silos, mills, driers, separators
- Air filtering systems
