Dual port high pressure UHP cylinder valve - D349
D349 valve for UHP gases is designed for keeping the highest level of purity of the gas. Easy withdrawal of liquefied gas thanks to the dual port technology. The D349 allows a high flow value at high pressure with its 6mm orifice size.
Key advantages
- Tied diaphragm design with minimal gas wetted volume
- Dual port design to withdraw liquid, vapor
- Easy withdrawal of liquified gas by pressurizing through vapor port
- Quick filling of liquified gas by releasing cylinder head pressure through additional vapor port
- Optional pressure relief device (PRD)
