Import Differential Pressure And Flow Regulators — Buy in Bulk from Supplier in China

The differential pressure and flow regulator is a control valve that maintains a preset pressure differential across a process line while optionally regulating flow rate. Shanghai Thinktank Process Management Co. Ltd. manufactures the unit in China and offers versions with internal excess‑pressure limiters to protect seats and plugs from over‑pressure. The regulator is supplied in cast iron for pressure class PN16 and in spheroidal graphite iron for PN25, with a stainless forged steel option (1.4571) for selected sizes. It accepts water as the working medium and is available with port sizes ranging from 1/2 inch to 12 inches.

Cast iron construction provides rigidity and wear resistance, while the spheroidal graphite variant improves crack resistance at higher pressures. The stainless forged steel version meets typical marine‑grade requirements and is often selected for corrosive environments. All models feature an adjustable seat temperature point, allowing fine‑tuning of sealing performance over the operating temperature range. The devices conform to ISO 9001 quality management practices as a standard in the valve industry.

These regulators are used in water treatment plants, petrochemical pipelines and industrial cooling systems where precise pressure control is critical. Shanghai Thinktank offers the units in bulk packaging, usually on wooden pallets with protective wraps, and can ship under FOB or CIF terms. Buyers should confirm the minimum order quantity, lead time and preferred Incoterm directly with the supplier, as the listing does not disclose those figures. Payment is typically arranged through a confirmed irrevocable letter of credit or telegraphic transfer after contract agreement.
