BPT13 Brass Balanced Pressure Thermostatic Steam Trap - Spirax Sarco
Spirax Sarco BPT13 brass thermostatic steam trap for condensate removal. PN16 rated, multiple configurations. Available at PC Engineering India.
Overview
The Spirax Sarco BPT13 is a balanced pressure thermostatic steam trap designed for efficient condensate drainage in steam systems. Built with a brass body conforming to BS EN 12165 CW 617N, this trap offers reliable performance in applications requiring compact, maintainable steam trapping solutions.
The BPT13 operates using a thermostatic capsule that responds to temperature changes relative to steam saturation. The capsule opens to discharge condensate when temperatures drop below the steam saturation point, then closes as live steam approaches. This balanced pressure design ensures energy-efficient operation by preventing steam loss while effectively removing condensate and non-condensable gases.
Available in multiple configurations including angled and straight connections, with optional union inlet and integrated strainer screen variants, the BPT13 adapts to diverse piping arrangements in industrial steam systems.
Key Features
- Brass body construction for corrosion resistance and durability
- Balanced pressure thermostatic operation for reliable condensate discharge
- Three capsule fill options: Standard (12°C subcool), Sub-cooled (24°C subcool), and NTS (4°C subcool) for critical applications
- Multiple body configurations: angled, straight, with/without union inlet
- Optional integrated strainer screen to protect internals from debris
- Readily maintainable design with field-replaceable capsule and seat assembly
- Compliant with European Pressure Equipment Directive 97/23/EC
- Stainless steel internals for extended service life
