Import Air Pressure Regulator 67cfr-225/Sb — Buy in wholesale FOB from Supplier in China

The 67CFR-225/SB is a filtered air pressure regulator designed for instrumentation and control systems in power generation and heavy industrial environments. Manufactured by Dongfang Yoyik Engnieering Co., Ltd. in Deyang, Sichuan Province, this unit handles instrument air supply with a 225 psig maximum inlet pressure rating and integral filtration. The SB suffix denotes a specific spring range and port configuration within the 67CFR series, a recognized Fisher legacy design pattern for pneumatic instrumentation. The supplier lists this part under stock code ZYR-DFYL-2025-2-6 alongside turbine and compressor spare parts, indicating its place within a broader power plant maintenance catalogue.

Construction follows standard cast aluminium body practice with nitrile diaphragm and seat materials typical for instrument air service. The filter element is commonly 40 micrometres nominal for this series, protecting downstream pneumatic positioners and converters from oil and particulate contamination. Spring ranges for the 225 variant usually span 0-30 psig or 0-60 psig output, though buyers should confirm the exact SB spring specification with the supplier. Differential pressure across the filter element should be monitored, replacement cartridges are standard industry consumables. The unit mounts directly on pipe stands or panel surfaces via standard bracket patterns.

Primary applications include instrument air supply to pneumatic valve positioners, I/P converters and actuator systems on steam turbines, gas turbines and auxiliary rotating machinery. Power plants, steel mills and petrochemical facilities maintain fleets of these regulators as maintenance spares. Buyers should verify port size (typically 1/4 inch NPT), filtration rating, spring range and whether the unit includes a pressure gauge. Dongfang Yoyik supplies this item alongside thermocouples, eddy current sensors and LVDT position sensors, suggesting technical familiarity with rotating machinery instrumentation. Confirm exact delivery terms, Incoterms and certificate of origin requirements directly with the supplier.

Dongfang Yoyik Engnieering Co., Ltd. operates from 4-3f, Building A, Huashan Platz in Deyang, Sichuan Province, China, postal code 618000. The company maintains a harbour trust tier on the platform with a recorded response rate of 0.00 percent and zero average response hours, which indicates no response history is available through this channel. Buyers should treat direct communication as essential rather than relying on platform-mediated response metrics. The supplier's address places it within Sichuan's heavy equipment manufacturing corridor, with proximity to Dongfang Electric Corporation's historical supply chain.

The supplier's product range centres on power plant and heavy industrial spare parts, including thermocouples, eddy current sensors, LVDT displacement transducers, vibration monitors and pneumatic instrumentation such as the 67CFR regulator series. The source description emphasises technical experience with thermal power plants, hydropower stations and metallurgical enterprises, though no specific verifications, certifications or client references are provided in the listing data. The company does not state its year of establishment, registered capital, employee count or revenue. Buyers should request business licence, ISO certification status and reference installations during initial qualification.
