GB Piston Accumulator

Model Explanation

1. Product code: HXQ stands for GB (Chinese National Standard) piston accumulator
2. Nominal inner diameter in mm
3. Nominal volume in L
4. Nominal pressure in Mpa
5. Connection type: M for metric thread, G for BSP thread, S for SAE thread, N for NPT thread, F for flange
6. Typical fluid: Y for hydraulic oil, R for emulsion, and H for water

For example, if a GB piston accumulator has inner diameter of 210mm, nominal pressure of 20Mpa, nominal volume of 10L, connection type of G2″ thread and working medium of hydraulic oil, it should be named as HXQ210-10/20-G32-Y.

Note:
1. The above products are usually manufactured in accordance with our enterprise standard (Q/BA 04-2009), while they could also be fabricated according to ASME and/or PED standards.
2. For piston accumulators whose nominal pressure is 20Mpa or lower, ASME standard inflation valve is applied, while ASME heavy type inflation valve is adopted for products whose nominal pressure is over 20Mpa.
3. The bold letters of line D in the above table indicate fluid port connection type.
4. Other special specifications could be negotiated.
