Valve manufacturer recommendations based on application scenarios: For oil, gas, and LNG, look to Neway (a global leader); for nuclear power, consider CNNC Suvalve or Jiangsu Shentong; for municipal pipeline networks, look at Shanghai Guanlong or Tianjin Gaotong; and for budget-conscious projects, consider Yuanda or Lianggong. First, determine the valve type and pressure rating, then select the appropriate manufacturer.
I.
Oil, Gas, and Globalization: Neway Valve
Neway Valve (Suzhou 603699): A world-renowned industrial valve manufacturer with 2025 revenue of approximately RMB 7.768 billion;
ranks first in China for valve export volume for consecutive years, with products sold in over 60 countries. Offers a full product spectrum including ball, butterfly, gate, globe, check, nuclear, control, subsea, and safety valves; holds approximately 40% of the global market share for LNG marine valves (industry data); features API 6D/API 607 fire-safe certifications and double/triple-offset butterfly valves (with wear-resistant Stellite metal seals)—the top choice for large-scale projects in oil & gas, offshore engineering, LNG, and nuclear power. CNNC Suvalve: A benchmark for nuclear-grade valves (holding over 40% domestic market share for isolation valves and gate valves used in Generation III nuclear power units)—key projects in nuclear power and petrochemicals. Jiangsu Shentong: Specializes in hard-sealed valves for metallurgy and nuclear power (blast furnace operations, coal chemicals); owns the “Dieqiu” (Butterfly-Ball) trademark—a Well-Known Trademark in China—and holds API/BV certifications; suitable for demanding operating conditions in metallurgy and chemical industries.
II. Municipal & General-Purpose: Guanlong, Gaotong, Sanhua
Shanghai Guanlong: A benchmark in municipal water utilities (large-diameter water supply/drainage, smart water management, and sewage treatment); Tianjin Gaotong: A comprehensive manufacturer based in North China (CE certification, 9 patents, pressure ratings from PN16 to PN420, full product range, customization available, and ample stock); Sanhua: Control valves/regulating valves (temperature and fluid control)—selection based on application scenarios for municipal networks and automation (electric/pneumatic butterfly valves with actuators).
III.
Specialty & Cost-Effective Options: Jiute, Chaoda, Yuanda
Jiute Valve (Wenzhou High-Tech Enterprise): Specialist in hard-sealed butterfly valves—bi-directional pressure hard-sealed and triple-offset butterfly valves (suitable for district heating, gas, small-to-medium chemical processing, and bi-directional pressure applications; non-standard customization supported); Zhejiang Chaoda / Beijing Valve General Factory: Specialty valves and mid-to-high-end products; Yuanda Valve / Lianggong: Budget-friendly general-purpose valves (competitive pricing for high-volume orders)—choose Jiute for hard-sealed and bi-directional pressure requirements, and choose Yuanda or Lianggong for budget-conscious projects.
IV. Five Key Factors for Selection
1. Determine Valve Type: Ball valve (rapid opening/closing/shut-off), butterfly valve (large bore/flow regulation), gate valve (full open/close), globe valve (throttling), control valve (process control), safety valve (pressure relief)—function dictates the type; 2. Determine Pressure Rating: PN16–PN420 or Class 150–600, based on system pressure; 3. Determine Material: Carbon steel, stainless steel, duplex steel, or low-temperature steel (e.g., LNG at -196°C); 4. Determine Sealing: Soft seal (zero leakage/low pressure) vs. hard seal (wear-resistant/high temperature/bidirectional pressure); 5. Determine Actuator: Manual, electric, or pneumatic (with positioner)—selected based on automation requirements.

Key Procurement Points for Overseas Buyers
1. Certifications: API 6D/API 607, CE, ISO 9001, explosion-proof (ATEX for actuators); 2. Standards: ASME/DIN/GB standards and flange connections; 3. Quality Assurance: Valve body warranty period and leakage class (ISO 5208/ANSI FCI 70-2); 4. Spare Parts: Availability of seals and valve stems; 5. Payment Terms: 30% deposit, with the balance paid after acceptance. Industry insight: The “best” valve depends on the application scenario and pressure—Neway (Oil & Gas);
CNNC Suvalve/Shentong (Nuclear Power); Guanlong/Gaotong (Municipal); Jiute (Hard Seal); Yuanda Lianggong (Budget-friendly).
Match the valve type, pressure, and material requirements first before discussing price.
