This product is a one-way flow valve with a working pressure range of -- / 16 bar, an environmental temperature range of minimum / maximum -20°C / +120°C, and a minimum / maximum media temperature of -20°C / +120°C. The materials used are outer shell: stainless steel, acid-resistant, and sealing: fluoro-rubber.
This guide describes the Series 344 unidirectional throttle valve, a corrosion‑resistant pneumatic flow control product. It operates at pressures up to 16 bar and temperatures from –20 °C to +120 °C, suitable for compressed air and oil media. The valve body is made of stainless steel with a fluorine‑rubber seal.
The document includes detailed flow‑rate tables (Qn 0.65–16 000 l/min) for various connection sizes (G 1/8 to G 1), material codes, and weight data. Contact information for Bosch Rexroth offices worldwide is provided at the end of the manual. This manual is written in Chinese.
