China Gate Valve Model Specification Description

China gate valve manufacturers today will focus on the gate valve models, gate valve specifications, gate valve model descriptions, and gate valve model representations.

1 China gate valve model preparation method standard

The gate valve model preparation method adopts the recommended national standard "GB/T 32808-2016 valve model preparation method"

2 China gate valve model preparation method

The type of gate valve consists of 7 units, which are valve type, drive method, connection type, structure type, sealing surface material or lining material type, pressure code or working pressure at working temperature, and valve body material. The model is represented as follows:

I (Unit 1) II (Unit 2) III (Unit 3) IV (Unit 4) V (Unit 5) - Unit VI (Unit 6) VII (Unit 7)

I (Unit 1): Valve Type Code

II (Unit 2): Drive Method Code

III (3 units): Connection form code

IV (4 units): Structure type code

V (Unit 5): Seat seal face material or liner material designator

VI (Unit 6): Nominal pressure code or operating pressure code at operating temperature

VII (Unit 7): Body Material Code
