1. Valves for Petroleum Plants

(1) Oil Refining Units: Mainly gate, globe, check, safety, ball, butterfly valves and steam traps. Gate valves account for 80% of total valves (3%-5% of unit investment).
(2) Chemical Fiber Units: Ball valves and jacketed valves (ball, gate, globe types).
(3) Acrylonitrile Units: Gate, globe, check, ball, steam trap, needle globe and cock valves. Gate valves make up 75% of total valves.
(4) Ammonia Synthesis Units: Gate, globe, check, steam trap, butterfly, ball, diaphragm, control, needle, safety, high & low temperature valves.

2. Valves for Hydropower Stations
Large-diameter, high-pressure safety, pressure reducing, gate, butterfly, emergency shut-off, flow control and spherical seal instrument globe valves.

3. Valves for Metallurgical Applications
Alumina: Wear-resistant slurry and regulating steam trap valves. Steelmaking: Metal-sealed ball, butterfly, oxidation ball, globe and four-way reversing valves.

4. Valves for Marine Applications
Shut-off ball, check and multi-way valves for offshore platforms.

5. Valves for Food and Pharmaceutical Applications
Stainless steel ball, non-toxic all-plastic ball and butterfly valves. General valves are in high demand.

6. Valves for Urban Construction
Low-pressure valves: Balance, soft-sealed gate and butterfly valves (eco-friendly and energy-saving types).

7. Valves for Urban Heating
Metal-sealed butterfly, horizontal balance and direct-buried ball valves (energy-saving, hydraulic balance).

8. Valves for Environmental Protection
Water supply: Center-line butterfly, soft-sealed gate, ball and air release valves. Sewage treatment: Soft-sealed gate and butterfly valves.

9. Valves for Gas Applications
Ball, cock, pressure reducing and safety valves.

10. Valves for Pipeline Applications
Forged steel full-bore ball, sulfur-resistant slab gate, safety and check valves for long-distance pipelines.
