Safety Valve SRV3 Type for Ammonia Freon Refrigeration Systems
The safety valve plays a safety protectian role in the system.When the system pressure exceeds the specified value,the safety valve opens,and a part of the gas/fluid in the system is discharged into the atmosphere/ outside of plpellne,so that the system pressure does not exceed the allowable value,so as to ensure that the system does not have an accident due to excessive pressure.

2、 说明 Instruction
安全阀在系统中起安全保护作用。当系统压力超过规定值时,安全阀打开,将系统中的一部分气体/流 体排入大气/管道外,使系统压力不超过允许值,从而保证系统不因压力过高而发生事故。
