Pressure relief valves for sanitary applications
Pressure relief valves improve productivity when compared to rupture discs.
Rupture discs require shutdowns after an overpressure event to replace disc elements. Product losses and downtime can be costly. Shutdown is needed to process the replacement after each rupture occurrence. This can be time-consuming and cost valuable time and money.
With the Clean Service series, LESER offers safety valves that reseat after an overpressure event and meet the high requirements of the biotech, pharmaceutical and food and beverage industry. The low dead space and the gap-free internal construction guarantee a high degree of cleanliness.
