摘要:
Cycling, self-checking block valve system that continuously cycles such that the user of the block valve system can determine if the system is operational at all times. A dual port block valve body contains two block valves which alternate between open and closed. The open and closing cycle is monitored for any changes, and the operator is alerted if one of the valves is not operating properly.
