Import Air Pressure Regulator 67cfr-600b — Buy in wholesale FOB from Supplier in China

The 67CFR-600B is a higher-pressure instrument air regulator from the same Fisher-heritage 67CFR family, distinguished by its 600 psig maximum inlet pressure rating and the B configuration suffix that typically indicates a specific porting, spring and body arrangement. Dongfang Yoyik Engnieering Co., Ltd. positions this unit within its power plant spare parts catalogue, stock code ZYR-DFYL-2025-literally-2025-2-6, alongside turbine bearings, compressor crossheads and sensor systems. The 600 series handles primary air supply reduction from plant compressors down to instrument air headers, rather than secondary distribution. Its cast aluminium construction with stainless steel trim is standard for this pressure class, though buyers must confirm exact wetted materials for sour gas or corrosive environments.

The B suffix generally denotes 1/2 inch NPT ports and a broader spring selection than lower-pressure variants, with output ranges commonly spanning 0-100 psig or 0-150 psig depending on spring selection. An integral filter with 5-micron element is more common in 600-series units given the higher velocity erosion risk from particulate at elevated pressures. Diaphragm construction shifts to reinforced nitrile or fabric-reinforced elastomer to withstand the greater pressure differential. The 600B serves as a pilot regulator or primary reducing station where 225-class units would be overwhelmed by header pressure. Dongfang Yoyik's application context, compressors, circulating compressors and steam turbine auxiliaries, suggests this unit is intended for upstream rather than final instrument service.

Industrial buyers for this regulator include power generation utilities, steel mill compressor stations, coking plants and oxygen plant instrument departments. The unit typically feeds air headers supplying multiple 67CFR-225 or similar second-stage regulators. Procurement should specify exact spring range, port size, filter micron rating and whether a pressure gauge is supplied. Given the 600 psig rating, relief venting and overpressure protection become critical safety considerations. Confirm with Dongfang Yoyik whether the unit includes internal relief, a separate external relief requirement, or a vented bonnet design. Material certificates, hydrostatic test records and calibration data should be requested for pressure-boundary components.

Dongfang Yoyik Engnieering Co., Ltd. is located at 4-3f, Building A, Huashan Platz, Deyang, Sichuan, 618000, China. The company holds a harbour trust tier on the trading platform with no recorded response activity, response rate 0.00 percent and zero average response hours. This absence of engagement metrics means buyers must initiate direct contact via the supplier's external channels to establish communication reliability. Deyang's industrial base includes significant power equipment manufacturing, providing plausible technical infrastructure for the spare parts catalogue described.

The supplier's stated specialisation covers generating unit accessories for power plants, steel mills, chemical systems, coking plants and non-ferrous metal processing facilities. Product categories include rolling mill components, compressor bearings, turbine parts and instrumentation such as the 67CFR regulators. The source description emphasises low-profit, user-satisfaction principles without substantiating manufacturing scope, quality certifications or client references. No information regarding establishment year, factory floor space, employee count, annual turnover or export licence is present in the listing. Buyers should conduct standard supplier due diligence including business registration verification, factory assessment and reference checks for comparable power plant supply contracts.
