Experts in oil and gas safety since 1999. WUXI NOVA Petroleum has specialized in the oil and gas industries since we first opened for business in 1999. In the nearly 26 years since then, we’ve developed solutions for refineries and petrochemical tanks, drilling, and production facilities worldwide.

Upstream equipment, midstream transportation, or downstream processing — no matter your industry, we have expertly engineered and tested safety products to protect every segment of your facility.

At WUXI NOVA Petroleum Valves, we recognize the value in protecting the environment to improve the standard of life for all. We are committed to proactively advancing the oil, gas, water, and wastewater industry to ensure long-term environmental solutions.

Complying with legal measures and conducting business ethically and transparently, we maintain and practice sustainable development for our employees, suppliers, customers, and community as a reliable partner, protecting the health and safety.

The valves find widespread applications across various industries, including: Oil & Gas, Chemical and Petrochemical Plants, Power Plants, LNG (Liquefied Natural Gas) Plants.

Valve Types We Supply

Comprehensive range of industrial valves engineered for performance and reliability

Ball Valve

Quarter-turn, full-bore, tight shut-off for on/off isolation

Control Valve

Precise flow regulation with linear, equal percentage, or quick-opening characteristics

Butterfly Valve

Compact, lightweight, high-flow capacity for throttling and isolation

Cast Steel Gate, Globe, Check Valve

Heavy-duty, high-pressure, durable for severe service

Forged Steel Gate, Globe, Check Valve

Compact, high-strength, ideal for critical high-pressure applications

On/Off Valves

Pneumatic, Electric, Hydraulic actuation for fast, reliable shut-off

Automatic Recirculation Valve

Self-actuating pump protection, prevents cavitation and overheating

Plug Valve

Quarter-turn, lubricated or sleeved, excellent for slurries and abrasive media

Special Alloy Valve

Inconel, Hastelloy, Monel, Titanium — for extreme corrosion, temperature, and pressure

Construction of Control Valve

Engineered components for precise flow control and long-term reliability

Control valves typically consist of several main components:

  • Valve Body – Primary structure housing internals and piping connections
  • Actuator – Pneumatic, hydraulic, electric, or electro-pneumatic for movement
  • Valve Trim – Plug, seat, stem — controls flow and withstands fluid conditions
  • Bonnet – Encloses stem, prevents leakage
  • Positioner – Enhances accuracy by adjusting valve position per signal
