Zhengguang wins Donghua package covering four valve types
The award covers gate, butterfly, check and pneumatic on/off valves, without a disclosed value.
The story explained
East China Engineering Science and Technology announced on 11 November 2026 that Zhengguang Valve Group was the successful supplier for gate, butterfly, check and pneumatic on/off valves. The procurement reference is YY2023001-001-HW-588, package /01.
The four valve categories form one package procured through an open comparative process. They are therefore reported as one procurement event. The result identifies the selected supplier but does not state quantities, diameters, pressure classes or materials for individual items.
The public notice omits the project site, price and delivery schedule. The buyer’s contact address in Hefei does not establish the equipment destination. An award announcement also does not establish manufacturing completion, delivery or commissioning.
Why it matters
Editorial analysis: The package combines isolation, backflow prevention and automated switching duties; the valve categories do not imply identical service conditions or standards.
Relevant toProject owners, EPCs and flow-control suppliers
