The BWLX Series is a concentric wafer butterfly valve designed for industrial flow control, featuring a DN50 to DN150 nominal diameter range (2" to 6") and a PN16 nominal pressure rating. It operates within a working temperature span of -5°C to +85°C, making it suitable for water, ethylene glycol, and other non-corrosive media. The valve incorporates an ISO5211 standard top flange for compatibility with various actuators and includes an eccentric pin on the stem to preserve structural integrity under load.
A wider EPDM seat design, which is replaceable, allows the valve to adapt to different flange types without compromising sealing performance. The sealing test is conducted at 1.1 times the nominal pressure, while the shell test meets 1.5 times the nominal pressure, ensuring reliability under standard industrial conditions. Typical applications include HVAC systems, water treatment plants, and general industrial pipelines where low-pressure, non-corrosive media is transported.
This series adheres to multiple international standards, including BS5155, EN593, and API609 for design, BS EN1092-2 for flanges, and BS EN558-1 for face-to-face dimensions. Importers sourcing from this supplier should confirm compatibility with their existing pipeline systems, particularly flange types and pressure ratings. The lever operation mechanism simplifies manual control, and the valve’s compact wafer design allows for easy installation between flanges without additional support.

Before ordering, verify the valve’s compatibility with your pipeline’s flange standard (BS EN1092-2) and face-to-face dimensions (BS EN558-1). Confirm the nominal pressure (PN16) and temperature range (-5°C to +85°C) align with your system’s operational limits, as mismatches can lead to leakage or failure.
Logistics details such as lead time, Incoterms (e.g., FOB, CIF), and payment terms are not provided in the listing. Request these from Zhejiang Banninger Fluild Control Co., Ltd. to avoid delays. Standard practice for valve shipments includes wooden crates or pallets, but packaging specifications should be confirmed to prevent transit damage.
Quality checks should include a review of the supplier’s test certificates for sealing (1.1 x PN) and shell (1.5 x PN) tests per BS EN12266-1 and API598. Inspect the EPDM seat for defects upon receipt and perform a pressure test before installation. Documentation such as material certificates and compliance declarations for BS5155/EN593/API609 should be requested to ensure traceability.
