The valve type description:
1. Type: according to the piping system design needs and all kinds of valve installation and use of their own features and factors such as decided to use what kind of valve.
2. Drive mode: according to the valves parameters, function, operation requirements and field conditions and choose the valve drive way. Our company can provide users with, manual, electric, pneumatic, hydraulic, electromagnetic, automatic, and other types of valve, can also according to the user.
3. Valve material: valve on the materials used in the use of common condition (medium, temperature, pressure, etc.) to decide.
4. Nominal pressure: valve specified temperature of work pressure, is for reference use round numerical, divided into different levels, with PN said, according to GB/T1048-1990 regulations, GB valve unit for MPa, LB valve with LB said.
5. Connection mode: according to the valve use condition and installation requirements choose different mode of connection, generally have threaded connection, flange connection, butt welding, the clamp connection, etc.
6. Structure length: the user does not have the special requirements, according to the valve executive design standards (GB, API, ANSI, BS, etc.) the provisions of manufacturing.
7. Structure: according to conditions (pressure, medium, temperature, installation position, etc.) and all kinds of valve structure characteristics, enhances strong points and avoid weaknesses to choose.
8. Nominal diameter: according to the provisions of GB/T1047 to selected to DN said, the unit is mm, lb valve with NPS said, the unit is (in).
9. According to the above several basically can determine a specific type of valve, the valve type of establishment sees the next day, for special, non-standard and lb valve type, reference JB/T308-1975 wrote by the enterprise.
The valve in the selection, still should according to different material conditions with reference to the pressure temperature rating of the valve material and determine the type.
11. Order:
A, to meet the performance parameters of sample a few specifications of the valve according to the user in the sample list of model selection. If you have special requirements (such as size, material, transmission device, connection size, structure, etc.) should add details.
B, electric valves denso accessories electric cabinet and automatic control valve of the servo amplifier, control box, pneumatic valve electromagnetic directional valve are by the customer from the match. Can also be made by our company and we provide supporting, but the price other meter. Construction, municipal, water supply and drainage, etc with valve, please refer to this company product sample A book.
