Representation method of electric gate valve model

Representation method of electric gate valve model; model name modification method; code name modification method
The electric gate valve is composed of an electric actuator and a gate valve body. The gate plate is controlled by the

power supply pressure to perform up and down linear operation to connect or close the fluid medium in the pipeline. The applicable pressure, temperature and caliber range are large, and it is especially suitable for Medium and large diameter pipes. Electric gate valves can be divided into various series. The actuators have on-off type and intelligent type, and the structure is very changeable. When selecting the type, the user should be familiar with the electric gate valve model preparation instructions to avoid selecting the wrong model, placing the wrong order and technology Unknown parameters caused problems such as exchange and return.
Electric gate valve model preparation instructions are mainly for the detailed explanation of the additional conditions of the gate valve, drive mode, connection form, structural feature, sealing material, pressure level and valve body material. Other customized or special product models are not applicable to this method. , Additional explanation is required.
The method of preparing the model of the electric gate valve:
Additional code for gate valve: WZ means bellows gate valve, DZ cryogenic gate valve, NKZ vacuum gate valve, PZ knife gate valve;
Type of gate valve: Z;
Drive mode: manual without code (usually omitted according to regulations), 2 electro-hydraulic, 3 worm gear, 5-bevel gear transmission, 6 pneumatic, 9-electric;
Connection mode: 4 flange connection, 6 welding, 7 pair clip type;
Structural form: 0 elastic gate, 1 open-rod wedge-type single gate, 2-open-rod wedge-type double gate, 3-open-pole parallel single gate, 4-open-pole parallel double gate, 5 concealed Rod wedge single gate, 6 concealed rod wedge double ram, 7 concealed rod parallel single ram, 9 concealed rod parallel double ram;
Sealing material: W valve body is directly processed, T alloy, X rubber, F fluoroplastic, H-Cr stainless steel, Y cemented carbide, M Monel alloy;
Pressure rating: PN1.0-32Mpa, 16=1.6MPA means the pressure is 16 kg, 150LB-1500LB means the American

standard pound pressure, 5-63K means the Japanese pressure;
Valve body material: Z-gray cast iron, Q ductile iron, T alloy, C carbon steel, P stainless steel 304, R stainless steel 316, V chromium molybdenum vanadium steel.
