Import Differential Pressure By-Pass Control Valve — Buy in Bulk from Supplier in China

The Differential Pressure By-pass Control Valve supplied by Zhejiang Banninger Fluild Control Co., Ltd. is a diaphragm‑type valve designed for automatic pressure regulation. It accommodates nominal diameters from DN50 to DN300 (2 in to 12 in) and is rated to PN 16. The valve maintains pressure‑difference precision within ±5 % and operates safely between - 5 °C and +85 °C. It conforms to BS EN 1092-2 flange standards and EN 558 Series 10 face‑to‑face dimensions.

The diaphragm construction provides zero‑friction movement, which yields rapid response to pressure changes. Sealing performance is verified at 1.1 × PN and the shell test at 1.5 × PN, typical for industrial control valves of this class. Common body materials for such valves are cast iron or carbon steel, and a standard ANSI‑B16.5 flange rating is often applied. Typical packaging includes a wooden crate with protective padding for sizes up to DN300.

This valve is suited for water, ethylene‑glycol and other non‑corrosive media in cooling‑water loops, heat‑exchanger bypasses and process‑control loops. Importers should request confirmation of the exact pressure‑range setting, minimum order quantity and preferred Incoterm from the supplier. The supplier indicates flexible packaging options and can arrange FOB or CIF shipment from the port of Shanghai, but exact lead times must be verified.
