TAV THERMOSTATIC

AIR VENT

- 352 -

Thermal actuator is filled at it’s free length with a
liquid having a lower boiling point than water. As
assembled, valve is normally open. On startup, air
passes through vent.As air is eliminated, hot steam
reaches vent and the thermal actuator fill vaporizes
to a pressure higher than line pressure. This forces

valve into seat orifice to prevent any further flow. Should
more air collect, it takes heat from the actuator, lowering
internal pressure. Line pressure will then compress thermal
actuator to open valve and discharge air. Valve lift auto­matically adjusts to variations.

THERMOSTATIC AIR VENT

Pressures To 650 PSIG (44.8 barg)

Temperatures to 750°F (400°C)

Sealed Stainless Steel Body — Lightweight, compact and

corrosion resistant. No bolts or gaskets. Eliminates body
leaks.

Self Centering Valve — Leak tight shutoff. Improved

energy savings. Assembly of actuator and valve to
impingement plate allows valve to self-align with center of
valve seat orifice. Provides long lasting valve and seat.

Temperature Sensitive Actuators — One moving part.

Stainless Steel, fail open, welded actuator for maximum
corrosion, thermal and hydraulic shock resistance.

Thermal and Hydraulic Shock Resistant — Impingement

plate plus welded construction prevent damage to actuator.

Hardened Stainless Steel Valve and Seat — Long life.

Lapped as a matched set for steam tight seal.

Inexpensive — Low initial cost.
Maintenance Free — Sealed unit. Replacement traps cost

less than repair of more expensive in-line repairable vents.

Directional Discharge — Pipe thread erosion prevented

by directing discharge to center of pipe.

Guaranteed — Guaranteed for 3 years against defects in

materials or workmanship.
