Yarway Series 711/721 Repairable Drip and Tracer Steam Traps

Yarway™ series 711/721 Unibody Plus disc trap is designed for light load applications such as steam tracing, steam line drip, and turbine drain. These traps are fully renewable in-line, energy efficient and easy to check.

The 711 is a simple straightway body. The 721 is a straightway body and has an integral wye strainer and blowoff valve. Both bodies accept the same renewal capsules without removing the bodies from the line. The standard capsule performs best when applied in service up to 450 psig. The HP capsule has been designed for 150-650 psig service to handle low load superheat service conditions.
