API 6A gate valve seals also must withstand erosive and corrosive effects from sand, scale, and particulate‑laden multiphase flows. Seal and seat profiles are optimized to shield softer materials from direct velocity streams, and hardfacing alloys on metal contact surfaces reduce wear. This combination improves valve longevity in severe service, including choke‑adjacent and high‑rate ... https://globalsealstech.com/product-category/oil-gas-seals/api-6a-gate-valve-seals/
