Conbraco 19-KDDA-150 Valve
The Conbraco 19-KDDA-150 Valve is a high-capacity, ASME Section I steam relief valve engineered for critical overpressure protection in industrial steam boilers, sterilizers, and pressure piping systems. This 3/4" MNPT x 3/4" FNPT safety relief valve is factory-set at 150 PSI and features a National Board certified relieving capacity of 929 pounds per hour. Constructed with a rugged bronze body and brass trim, it utilizes a Teflon PFA seat to ensure a positive seal while resisting corrosive boiler chemicals and excessive mechanical vibration. The unit includes a stainless steel spring and a two-control-ring design, allowing for precise adjustment and a "tuned" blowdown that minimizes steam loss during discharge. Professionals prefer this model for its top-guided alignment and integrated tapped body drain, which facilitates the safe removal of condensate from the valve body.
- ASME Section I Certified: National Board capacity certified for high-pressure steam safety valve applications.
- Durable Seating: Teflon PFA soft seat provides superior chemical resistance and reliable shut-off compared to metal-to-metal alternatives.
- High Relieving Capacity: Delivers a 929 PPH flow rate at a 150 PSIG set point for robust system protection.
- Installation Efficiency: Features a wide wrenching hex on the base to simplify mounting in tight boiler manifolds.
- Corrosion Protection: Equipped with stainless steel springs as standard to maintain set-pressure integrity over time.
Common Questions
What is the maximum temperature rating for this valve?
This 19 Series model with brass trim and a Teflon seat is rated for a maximum operating temperature of 406°F.
Can this valve be mounted horizontally?
No. To ensure proper drainage and mechanical operation, the Conbraco 19-KDDA-150 must be installed in a vertical upright position directly on the pressure vessel or piping.
How do I handle condensate buildup in the valve?
The valve features a 1/8" NPT tapped body drain. Install a drain line to this port to prevent water from accumulating on the seat, which can cause scaling and premature failure.
