Item Number CT300YS-3/4, Thermostatic Steam Trap Balanced Pressure Design

Features
• Compact "Y" pattern forged steel body.
• Thermostatic capsule immediately responds to changes in pressure and temperature.
• Can be installed in any position. Vertical installation ensures the unit to be freeze-proof when discharging to a gravity return or atmosphere.
• Integral strainer. "Y" pattern design allows for in-line replacing or cleaning of screen.
• In-line replaceable thermostatic capsule and seat.

Optional high and low temperature thermostatic capsules are available upon request.

Colton has a policy of continuous product research and improvement and reserves the right to change design and specifications without notice.
