Gate valve or Ball Valve?
in steam systems simply because they are full port. It isn't always possible or practical to drip before an isolation valve. A globe valve in a horizontal steam line will present a "dam" and back up condensate, and cause hammer. Large ball valves have there own problems, you think Gates get stuck! Perhaps the question of installation with stem up, horizontal or down should be asked. Stem up and all the c**p in the pipe lodges in the lower channel. Stem horizontal and the side channel is full. Down and the blade has a clean seating area? Any thoughts?
