Ventil se samodejno odpre, ko tlak dose\u017ee kriti\u010dno raven, sprosti odve\u010dni tlak in s tem za\u0161\u010diti kotel in cevovode pred po\u0161kodbami.<\/li>\n<li><strong>Samodejna sprostitev tlaka<\/strong>: Takoj, ko sistemski tlak prese\u017ee nastavljeno vrednost, se odpre varnostni ventil, ki omogo\u010di izstop odve\u010dne hladilne teko\u010dine iz sistema. Ko tlak pade na varno raven, se ventil samodejno zapre.<\/li>\n<li><strong>Prepre\u010devanje v sili<\/strong>: Uporaba varnostnega ventila prepre\u010duje izredne razmere, kot so eksplozije ali pu\u0161\u010danje hladilne teko\u010dine, do katerih lahko pride zaradi pregrevanja ali okvar v sistemu.<\/li>\n<li><strong>Namestitev in konfiguracija<\/strong>: Varnostni ventili so name\u0161\u010deni na kotlih, ceveh in drugih kriti\u010dnih mestih ogrevalnega sistema.
