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
