Diaphragm-type steam trap "DX1 model"
Dedicated to sanitary piping! Easy to attach and detach with a Heller connection.
The Diaphragm Steam Trap operates by using the temperature difference between steam and condensate entering the trap to open and close the valve. [Features] 1. Sanitary Design for High Hygiene Standards Crafted from corrosion-resistant SUS316 with a wetted surface roughness of Ra 1.6 μm. Ferrule connections enable quick assembly, cleaning, and maintenance—ideal for pharmaceutical and food lines. 2. Ultra-Compact Design (30 mm Face-to-Face, 0.18 kg) With an industry-leading height of just 30 mm, it fits seamlessly into tight spaces and complex layouts, significantly increasing machine design flexibility. 3. Strict Temperature Control with Open Temp at "Saturated Temp −5°C" Responds quickly to discharge condensate, preventing heat loss. Ensures consistent quality and energy savings in high-temp steam applications like SIP (Steam-in-Place) and autoclaves. 4. Zero Residual Water Option: Model DX1R (With Orifice) Eliminates condensate buildup inside the trap even when steam supply stops, removing the risk of bacterial growth and liquid pooling. Meets the highest hygiene standards for biopharma processes. 5. Backflow Prevention & Easy Maintenance with Dedicated Check Valve Pairs with the optional sanitary check valve (CX1) to prevent backflow and simplify piping installation. The separate structure allows independent inspection and replacement of each component.
