Steam drains, sampling lines and start-up bypasses on a boiler all need throttling, and a gate valve cannot do it without seat damage. The globe plug moves perpendicular to the seat, so control is progressive and the seat survives part-open duty. Chrome-moly F22 body for 540 °C steam, pressure-seal or bolted bonnet, butt-weld ends, rising stem.
