Valve model discussion
Thread Content
There are several valve models that are relatively rare in the unit. Please discuss the meaning and related standards: Z2Z41H, Z2 imitation 41H 41Y-2.5PⅢ, and what is the service temperature of the valve body material P? This post was last edited by bingyu252 on 2009-2-9 14:57 ]
P is the valve body material 304/0Gr19Ni9. The applicable temperature is roughly between -40 and 200 degrees. When selecting the upper temperature limit, the pressure level of the valve must be considered. Different manufacturers have different situations.

The Z2 on the front seems to be a valve with two purge holes, but I don’t know how to explain it.
Take a photo or take out the instructions for these types of valves from your company and look at them. I haven’t seen any other codes added to explain them before!
P is generally for stainless steel, the temperature is generally within 200
H material is made of alloy steel, Y is made of hard alloy steel, P material is boronized, and the imitation is made with venting.
No one knows what the valve body 41Y-2.5PⅢ represents.
The valve body material code p represents the material of chromium nickel titanium steel, represented as 1Cr18Ni9Ti, ZG1Cr18Ni9Ti 2.5 represents the nominal pressure PN0.25MPa 41Y-2.5PⅢ indicates that the connection type is flange connection, the structure is an open-stem wedge-type single gate valve, the sealing surface or lining is carbide, the nominal pressure is PN0.25MPa, and the valve body material is chromium-nickel-titanium steel. The operating temperature is not indicated, and the applicable temperature should be between -40 and 200 degrees. Other valve body material code Valve body material code Gray cast iron Z 1Cr5Mo, ZG1Cr5Mo I Malleable cast iron K 1Cr18Ni9Ti, ZG1Cr18Ni9Ti P Ductile iron Q 1Cr18Ni12Mo2Ti, ZG1Cr18Ni12MoTi R Copper and copper alloy T 12CrMoV V Carbon steel C ZG12CrMoV V
41Y-2.5PⅢ indicates that the connection type is flange connection, the structure is a rising stem wedge single gate valve, the sealing surface or lining is carbide, the nominal pressure is PN0.25MPa, and the valve body material is chromium nickel titanium steel. The current standard 2.5 should refer to 2.5MPa. P represents that the valve body material is chromium nickel titanium steel, but what does the III behind it represent?
