Zhejiang Dongri Valve Expands Global Supply of High-Performance Ball Valves for Oil, Gas and Industrial Applications

Located in the Puyi Industrial Zone, Oubei Town, Yongjia County — widely known as the "Hometown of Pumps and Valves in China" — Dongri Valve integrates R&D, design, manufacturing and sales under one roof. With nearly three decades of industry experience and a registered trademark (CNDR, Class 7), the company has built a solid reputation for quality and reliability, serving customers across domestic and international markets.

A Comprehensive Ball Valve Portfolio

Dongri Valve's leading product is the Ball Valve, offered in one of the industry's most complete series to meet diverse operating conditions:

• API Ball Valve — manufactured to American Petroleum Institute standards, ideal for oil and gas, pipeline and high-pressure industrial service;
• Floating Ball Valve — a cost-effective, widely applied design where the ball floats between seats, delivering reliable shutoff for medium- and low-pressure systems;
• Trunnion Mounted Ball Valve — a fixed-ball design with upper and lower trunnion support, engineered for large-diameter, high-pressure applications where floating designs are unsuitable;
• Metal Hard Sealed Ball Valve — featuring metal-to-metal seating for extreme high-temperature, abrasive and corrosive environments where soft-seated valves cannot survive;
• Forged Steel Ball Valve — produced from forged billets for superior mechanical integrity, suited for high-pressure, high-temperature and critical-service applications.

All products comply with international and national standards including GB, JB, HG, ISO, API, ANSI, BS, DIN, NF and JIS, and non-standard specifications can be custom-manufactured to meet specific customer requirements.

Advanced Materials and Wide Technical Range

Dongri Valve selects body materials precisely to match each application, offering carbon steel (WCB, WCC, A105), low-temperature steel (LCB, LCC, LC6, LC9, LF1, LF2, LF3), high-temperature steel (WC6, WC9, C5, CA12, CA15, F11, F22, F5), austenitic stainless steel (CF8, CF8M, CF3, CF3M, F304, F316, F304L, F316L, F347), duplex stainless steel (4A, 5A, F51, F55) and other special alloy materials.

Valve sizes range from DN15 to DN1000 (1/2" to 40"), with working pressures from PN1.6 MPa to 42.0 MPa (150 Lb to 2500 Lb) and operating temperatures from -196°C to 800°C. Operation modes include manual, worm gear, electric, pneumatic and hydraulic actuation — enabling Dongri to supply a complete Ball Valve solution for virtually any flow-control scenario.

"Customer First, Quality Foremost is the philosophy that has guided Dongri Valve for nearly 30 years," said Mr. Wang Zhixiang, founder and legal representative of the company. "Whether a customer needs a standard API Ball Valve, a compact Floating Ball Valve, a large-bore Trunnion Mounted Ball Valve, an abrasion-resistant Metal Hard Sealed Ball Valve, or a high-integrity Forged Steel Ball Valve, every unit is engineered and inspected to deliver dependable performance under the most demanding conditions."

Proven Across Industries

Dongri Valve products are widely deployed across petroleum, natural gas, chemical, energy, pharmaceutical, metallurgy and papermaking sectors, where reliable flow control is critical to safe and efficient operations. The company's ability to combine broad material selection, wide pressure-temperature ranges and multiple actuation options makes it a preferred partner for engineering contractors, distributors and end-users worldwide.

Looking Ahead

As global demand for high-performance, application-specific valves continues to grow, Zhejiang Dongri Valve remains committed to advancing product design, expanding its manufacturing capacity and strengthening quality control. The company warmly welcomes global purchasers, EPC contractors and distributors for technical consultation, sample evaluation and long-term win-win cooperation.
