YT-520 Snap Acting Relay

Brand: Rotork YTC
The YT-520 Series is a snap-acting relay that senses supply pressure and changes the direction of the supply air flow when the supply pressure level is lower than the set pressure level.

By using a snap-acting relay, the valve system can “fail freeze” as the supply pressure fails.
Features
  • Switches pressure flows when abnormal pressure detected 
  • Stem can be extended and connected 
  • Able to lock actuator in its position 
  • Responses to very small changes to supply pressure with high accuracy 
  • Enhanced versatility by having different material for body and options 
  • Internal 100-mesh screen filters small dust entering into the product
