Is there any price difference between J41H-16 DN25 and J41H-16C DN25?
I don’t know which manufacturer’s model it is; it probably has nothing to do with the price. The price is determined by the material, the connection method, and the pressure requirements, and yours is more or less the same in those aspects.

Reply 1# w464706128: The designation J41H-16 is inappropriate; the correct format is J41H-16C.

Since the pressure of your stop valve does not exceed 2.5 MPa, it is not possible to omit the valve body material code C.
