Import Differential Pressure Switch Cms — Buy in wholesale FOB from Supplier in China

The Differential Pressure Switch CMS from Dongfang Yoyik Engnieering Co., Ltd. is a mechanical switching device designed for monitoring pressure differentials in industrial fluid systems, particularly in power plant turbine and generator auxiliary circuits. It operates within a range of 0 to 100 kPa, with a switch point accuracy of ±1.5% of full scale and a hysteresis of 2% to 5%, matching typical industrial-grade thresholds. The unit features a stainless steel diaphragm and brass housing, with IP65 protection rating, and connects via M20 x 1.5 threaded ports as standard.

This switch is built for environments with moderate vibration and humidity, common in power generation facilities. The internal mechanism uses a calibrated spring-loaded diaphragm with a microswitch actuator, typical for analog differential pressure control in steam and hydraulic systems. It does not include electronic output signals; it is purely mechanical, making it suitable for fail-safe applications where power loss must not disable the pressure monitoring function. Variants may include adjustable set points, though the base model is factory-set at 15 kPa differential.

Buyers in power plant maintenance, industrial automation, and HVAC system integration commonly source this switch for boiler feedwater lines, air compressor circuits, and filtration system monitoring. It is supplied in bulk packaging of 5 to 10 units per carton, with foam inserts to prevent diaphragm damage. Lead times are typically 4 to 6 weeks ex-factory, and trade terms are FOB Qingdao or CIF, depending on buyer arrangement. Verification of pressure calibration certificates is recommended prior to installation.

Dongfang Yoyik Engnieering Co., Ltd. is based in Deyang, Sichuan Province, China, and operates as a manufacturer and trader of industrial spare parts, with a focus on turbine and generator components. The company supplies filters, valves, sensors, and control devices used in power generation systems. Its trust tier is listed as harbor, indicating verified export documentation and shipping compliance, though no certifications such as ISO or CE are claimed in the listing. Response rate and average response time are not available, suggesting limited real-time buyer engagement.

The company does not publish its history, employee count, or annual turnover. Its product range is defined by the spare parts listed, including LVDT sensors, RTDs, pressure transmitters, and mechanical switches like the CMS model. There is no evidence of in-house R&D or custom engineering capabilities. The listing confirms no direct client names or project references. Buyers should treat this supplier as a component distributor with manufacturing ties, not a system integrator.
