The DN100 Class 150 gate valve is made from ASTM B148 C95800 nickel aluminum bronze. It's built for seawater, brine, and marine systems – where corrosion kills ordinary valves. The cast bronze body has a bolted bonnet and a flexible wedge. That wedge keeps both seats sealing even when temperatures move up and down. On the seat and disc we put 13 percent chrome plus a Stellite 6 hardfacing. The stem is Monel K500, known for high strength and excellent resistance to saltwater attack. Connection is RF flanged to ASME B16.5. A handwheel operates the valve – simple and straightforward. Design follows MSS SP‑80, with full compliance to ASME B16.34, and each valve gets tested to API 598.
