Import Accumulator Oil-Return Globe Valve Shv20 — Buy in wholesale FOB from Supplier in China

The accumulator oil-return globe valve SHV20 is a hydraulic control component designed for power generation systems, manufactured by Deyang Dongfang Yoyik Engineering Co., Ltd. in Deyang, Sichuan Province, China. This valve regulates oil return flow from hydraulic accumulators to prevent system pressure loss and ensure controlled depressurisation. The SHV20 designation indicates a specific size and pressure rating within the manufacturer's hydraulic valve range, suitable for integration with bladder accumulator systems rated at 31.5 MPa working pressure. The valve body is constructed from carbon steel or stainless steel, with a globe-style seat design that provides positive shut-off and throttling capability for oil media in thermal power and hydropower applications.

Globe valves of this type typically feature a rising stem with handwheel or actuator operation, a renewable disc and seat ring, and flanged or threaded end connections. The SHV20 is compatible with mineral oil-based hydraulic fluids and fire-resistant phosphate ester fluids used in turbine electro-hydraulic (EH) control systems. Standard material grades for such valves include ASTM A216 WCB carbon steel or ASTM A351 CF8M stainless steel, with NBR or fluorocarbon (FKM) seals for oil compatibility at temperatures from -20°C to 120°C. The bellows seal option, referenced in related Yoyik products such as the DFJ65-1.6P, may be available for zero external leakage requirements. Pressure ratings typically follow GB or ASME standards, with nominal pressure PN16 to PN40 or Class 150 to Class 300 equivalents.

Primary applications include accumulator discharge lines in steam turbine hydraulic systems, emergency oil return circuits, and maintenance isolation points in power plant lubrication and control oil networks. The valve serves utilities, power generation contractors, and maintenance service providers conducting overhauls of 300MW and larger turbine-generator units. Buyers should verify the exact connection size, pressure rating, and seal material with Deyang Dongfang Yoyik Engineering Co., Ltd. before ordering, as the SHV20 may be configured for specific accumulator models such as the NXQL10/31.5 or NXQ-A-16/20-I-Y. The supplier maintains inventory of related hydraulic components including servo valves, pressure relief valves, and accumulator charging equipment.
