Type 313

Overflow Trap

Deaerators, tanks with steam blankets, produce additional liquid as the steam condenses. The 313 Overflow Trap traps and relieves this condensate through its internal pilot without the steam blanket escaping. Buoyancy of its float ball provides force to actuate internal pilot operated single seat valve assembly to relieve condensate and overflow to drain. The overflow trap should be installed in an upright position.
