Import Fire Protection Signal Feedback Butterfly Valve — Buy in Bulk from Supplier in China

The fire protection signal feedback butterfly valve offered by Zhejiang Banninger Fluild Control Co., Ltd. is designed with a wider EPDM seat that can be replaced and a streamlined SS304 disc. It conforms to BS5155, EN593 and API609 design standards and features an ISO5211 top flange that fits a range of flange types. Nominal diameters are supplied from DN50 to DN250 (2" to 10"), with a nominal pressure rating of PN16 and an operating temperature range of - 5 °C to +85 °C. The valve includes an eccentric pin on the stem that preserves stem integrity while providing a position indicator for signal feedback.

Material selection follows common industry practice for fire‑rated butterfly valves, where EPDM provides chemical resistance and SS304 offers corrosion resistance in the disc. The ISO5211 top flange and BS EN1092‑2 flange standards facilitate interchangeable installation across different plant layouts. Typical butterfly valves of this class are tested to a sealing pressure of 1.1 PN and a shell pressure of 1.5 PN, matching the specifications listed for this product. Standard testing procedures such as BS EN1074 and API598 are applied to verify leak tightness and mechanical strength.

The valve is suitable for water, ethylene glycol and other non‑corrosive media in fire protection loops, making it a common choice for petrochemical plants, power stations and large‑scale HVAC systems. Buyers such as engineering contractors and plant owners often request the position‑feedback feature to integrate with supervisory control systems.
