Gaoshan Valve —Shijiazhuang Sales Center

A41H offering listed separately from the other safety-valve models.
The A41H safety valve is a distinct model reference in the sales center’s own catalog. Buyers should use that reference together with the intended service conditions, rather than assume that another Gaoshan safety-valve model has the same construction. Connection dimensions, pressure setting and documented relieving performance should be agreed for the actual unit being quoted.
