This 15mm check valve with isolator, designated model S15A1.0, is a component supplied by Deyang Dongfang Yoyik Engineering Co., Ltd. for power generation applications, including use at facilities like the Madura power plant. The valve features a 15mm nominal bore, which is a standard metric size for small-bore piping systems, and is designed to prevent backflow while allowing an isolation function for maintenance. Its construction is suited to the high-pressure, high-temperature environments found in thermal power stations.
The unit is part of a broader catalogue of power plant spare parts from this Deyang-based supplier, which includes globe valves, pressure relief valves, mechanical seals, and hydraulic components. Check valves of this type are typically manufactured from stainless steel or carbon steel alloys, with internal components like the disc and seat hardened for wear resistance. The isolator section allows the valve to be positively shut off, enabling safe servicing of downstream equipment without depressurising the entire line.
Buyers for this valve are typically power plant operators, maintenance contractors, and engineering procurement firms sourcing replacement parts for turbine lubrication, sealing oil, or hydraulic control systems. The supplier's listing indicates a focus on safety and reliability for harsh operating conditions. Specific trade terms, such as minimum order quantity, lead time, and exact pricing, are not provided in the listing and should be confirmed directly with Deyang Dongfang Yoyik Engineering Co., Ltd. to ensure they meet your project's requirements.

Before ordering the 15mm check valve with isolator S15A1.0 from Deyang Dongfang Yoyik Engineering, verify the exact technical specifications against your system requirements. Request the manufacturer's data sheet detailing the pressure-temperature rating, material certifications (ASTM grades), and connection dimensions. Confirm whether the valve is new, refurbished, or a compatible aftermarket part, as this affects warranty and reliability in critical power plant service.
Clarify all trade and logistics terms directly with the supplier. Confirm the minimum order quantity, unit price, and accepted payment methods. For shipping, determine if the price is quoted FOB (Free on Board) a Chinese port like Shanghai or CIF (Cost, Insurance, Freight) to your destination port. Get a firm production and delivery lead time commitment in writing, and discuss packaging requirements to protect the valve during transit.
Implement quality checks upon receipt. Inspect the valve for any visible damage from shipping. Verify the markings on the valve body match the S15A1.0 model and any provided documentation. If possible, have the valve's pressure integrity tested by a qualified workshop before installation, especially if it is for a safety-critical system. Maintain all received documentation, including material test reports and packing lists, for your plant's maintenance records.
