Sanitary pressure relief valve Operating principles
●Pressure relief valve is closed normally
●Pressure is set by adjusting the spring
●When pressure in equipment exceeds the set pressure, the valve will open to let the medium pass through to relief the pressure in equipment
Sanitary pressure relief valve Technical features
●Non-retention
●No dead point
●Higher levels of safety
●Less downtime
●Higher yields
● Production process complies with 3A, DIN, ISO sanitary valve norms
