      Valve interlock system is used for realize safety operation sequence in process requirement,
      
reduce manual error operation, ensure life property safety. General application such as: Receive
      
and launch system of long-distance oil and gas pipeline, replace safety valve, load and unload
      
hose of oil tank truck.
      

      
When valve located in risk region、or region which space is limited, or place which emit toxic and harmful gas, our valve remote transmission facility could operate valve remotely, ensure safety and 
      
convenience for operation person, valve which is big torque and number of turns is more in petrochemical industry, our portable valve actuator could open and close valve quickly, enhance work efficiency, save cost, reduce labor force.

      PSV system interlock application
      
		  
      PSV system maintenance operation in operation equipment, whether on land or at sea, to ensure pressure relief channel is unblocked during any time scope in work period. General pipe equipment has release system, maintenance operation at same time maintain continuous production.
      
Pipe system which has two or more safety relief valve generally there is break valve in up and down end for every safety relief valve. Must ensure shut off valve which in spare pipeline open, then could close shut off valve on pressure relief valve in operation pipe line. Special when distance between pressure relief and shut off valve is far or couldn’t see mutual, sequence problem for safety operation will become more acute，Various API and ASME specification all acknowledge 
      
this harmful thing, and suggest to use valve safety interlock to eliminate producing harm.
      

      
		
      
	         
	   
	    
      
		
      
		  
      Interlock application for transceiver in pigging station
      
		  
      With more and more pipe construction project, long-distance pipeline construction、operation and management will become one of importance works for domestic oil company.
      
long-distance pipeline general load high pressure or toxic and harmful substance according to different conveying medium. During pipe pigging, pig assembly and remove must intervention operation manual, and this process must correct isolation through receiver and launcher, pressure release and discharge operation, working personnel could safely open blind plate.
      

      
		
      
	         
	   
	    
      
		
      
		  
      Interlock application for electric valve
      
		  
      Safety mechanical interlock combined device is used for MOV electric valve.
      

      
These MOV valves usually assembly to blind plate launcher/ receiver system、pigging station. These electric execute facility valve combine interlock program for manual operation, open and close valve.
      

      
MOV valve interlock system must ensure valve locked in complete open and/or complete close position, interlock electric、hydraulic pressure or air pressure operation mode and manual control. Still maintain interlock program normal operation even if in power failure situation.
