D Series | Diaphragm Steam Traps
Steam Traps D Series | Diaphragm Steam Traps
DV1
December 2, 2024 : New size for DV1, size 1" was released.
Features/Applications
Features
Built-in high-volume bypass
No bypass pipe is necessary, thus enabling a large reduction in product and pipe installation costs.
Enables reduced startup time, scale elimination, and urgent handling in the event of abnormal temperatures.Compact design
Can be installed in small spaces.
Stainless steel
Highly resistant to corrosion.
No steam leaks
Operates below saturation temperature, resulting in no steam leaks and great energy saving performance.
Easy maintenance
Less components make maintenance and inspection easy.
Typical applications
Suitable for foodstuff devices, bio devices, compact heat exchangers, tank heating, main heat pipes, steam tracing, cleaning devices, and other such applications.
