Reduced maintenance: Over the extended life of the equipment, vacuum retrofits can reduce maintenance by as much as 60% according to a recent study comparing vacuum to air magnetic 15-kv breakers.
The TK-DL can test pressure vacuum breakers, reduced pressure backflow preventers or double check valve assemblies.
TK - DL可以检测压力真空断路阀，减压防回流阀或双止回阀总成。
