Import Butterfly Valve - Av 13 - Bare Type — Buy in Bulk from Supplier in South Korea (Republic Of Korea)

The AV‑13 butterfly valve is offered as a bare‑type wafer unit with a JIS 5K/10K, ANSI Class 150 and PN 6/10/16 (BS4504) flange rating, suitable for sizes from 14 in to 48 in. It is rated for a maximum operating pressure of 10 kg/cm² (0.98 MPa) and has been tested at 15 kg/cm² (1.47 MPa) on the body and 11 kg/cm² (1.08 MPa) on the seat. The body may be cast iron, cast steel, ductile iron or stainless steel, while the disc is available in stainless steel or aluminium bronze, the stem in SS 410, and the seat in EPDM, NBR or PTFE.

The listed material options reflect common industry practice for medium‑pressure butterfly valves. Cast iron and ductile iron provide good rigidity, whereas stainless steel offers corrosion resistance for aggressive fluids. Aluminium bronze discs are chosen where wear resistance is critical. EPDM seats operate between - 20 °C and +120 °C, while NBR seats cover - 10 °C to +80 °C; PTFE seats are used where chemical inertness is required. These choices align with typical standards such as ISO 5752 and API 609 for wafer‑type valves.

Typical end‑users include water‑treatment plants, chemical processing facilities and food‑grade pipelines that need a reliable shut‑off device without complex machining. Buyers usually request bulk quantities and will negotiate trade terms such as FOB or CIF, packaging in protective crates, and a lead time that matches their project schedule. Confirmation of the exact material grade, seat type and any optional coating (PFA or Viton) should be obtained before placing an order to ensure compatibility with the intended service.
