Spirax Sarco BT6 Horizontal Sanitary Balanced Pressure Thermostatic Steam Trap

Overview

The Spirax Sarco BT6 Horizontal Sanitary Steam Trap is a balanced pressure thermostatic trap engineered specifically for clean and pure steam applications in pharmaceutical, biotech, and food processing industries. This steam trap efficiently removes condensate with minimal retention while operating close to steam saturation temperature.

Constructed entirely from 316L stainless steel, the BT6 features a crevice-free body design with an angled seat that ensures complete self-draining capability. The trap is manufactured and packaged in an ISO Class 7 clean room environment with protective end caps and sealed packaging, making it ready for installation in hygienic process systems.

Designed in accordance with ASME BPE standards and compliant with PED requirements, this sanitary steam trap meets stringent regulatory requirements including FDA CFR Title 21, USP Class VI biological reactivity testing, and ADI-free certification for pharmaceutical-grade applications.

Key Features
