Import Diff Pressure Switch Cs-V — Buy in wholesale FOB from Supplier in China

The Diff Pressure Switch CS-V is a mechanical pressure-sensing device designed for industrial power plant applications, specifically monitoring differential pressure across filters, ducts, or fluid systems. It operates within a range of 20 to 180 PSI, with a mechanical dial interface and robust construction suitable for high-vibration environments. This model is manufactured to replace original equipment in turbine and boiler control systems, with direct compatibility to existing piping and mounting standards used in Chinese and international power generation units.

The switch housing is constructed from cast aluminum with a sealed IP65 rating, and internal components include a stainless steel diaphragm and bimetallic sensing elements. The contact mechanism is rated for 10A at 250V AC, with normally open and normally closed options. These are typical specifications for industrial differential pressure switches in power generation, where reliability under thermal cycling and dust exposure is critical. The unit does not include electronic components, making it resistant to electromagnetic interference common near transformers and control panels.

This switch is primarily purchased by maintenance departments at coal-fired and combined-cycle power plants in Asia and Eastern Europe, often as a direct replacement for obsolete or damaged units. Buyers typically require batch quantities of 5 to 50 units per order, with delivery via sea freight under FOB Qingdao terms. Packaging is in corrugated cardboard with foam inserts, and each unit is labeled with a serial number traceable to the manufacturer's production batch. Lead time is typically 2 to 4 weeks after confirmation of order details.

Dongfang Yoyik Engnieering Co., Ltd. is based in Deyang, Sichuan, China, and operates as a manufacturer of spare parts for power generation equipment. The company supplies components including LVDT sensors, RTDs, pressure switches, and temperature gauges to repair and maintenance teams in the energy sector. Its listing shows no claims regarding company size, years in operation, or export history. The supplier has a harbor trust tier, indicating verified business registration and physical address, but no response rate or average reply time is recorded, suggesting limited active communication on the platform.

The supplier does not state whether it holds ISO certification, maintains a quality control lab, or performs end-of-line testing on pressure switches. It does not list any international clients or certifications such as CE or UL. The product range suggests in-house machining and assembly capability, but no details are provided on calibration procedures or traceability systems. Buyers should treat this as a sourcing option for mechanical replacements, not as a certified OEM supplier.
