Side Entry Trunnion Mounted Ball Valves
- (TRUNNION MOUNTING) A style of mounting the disc or ball on the valve shaft or stub shaft with two bushings diametrically opposed.
- (ball valve) any valve that checks flow by the seating of a ball
- (Ball valve) A ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur.
- (Ball valve) used to regulate the flow of water and to shut off skimmers, drains and other lines in order to vacuum or run a spa or water feature.
- A one-way valve that is opened and closed by pressure on a ball that fits into a cup-shaped opening
- An act of going or coming in
- A place of entrance, such as a door or lobby
- a written record of a commercial transaction

- introduction: the act of beginning something new; "they looked forward to the debut of their new product line"

West Seattle Railroad Bridge 5
This is the West Seattle railroad bridge on the west side of the Duwamish River. It's a patented Strauss "heel-trunnion" bascule bridge. It's in the down position with a train traveling left to right heading into West Seattle.
According to historylink.org:
How It Works
The typical bascule bridge works like a seesaw with a moveable leaf and a counterweight attached to its "heel," a pivot much like the pivot at the center of a seesaw. When the bridge opens, the counterweight dips into a counterweight pit. This seesaw-like arrangement enables a bridge to open and close with a minimum of power provided by a motor.
The West Seattle Railroad Bridge is a Strauss "heel-trunnion" bascule bridge and this differs in that the moveable leaf and counterweight each rotate around separate heels (called "trunnions"). Thus the counterweight rises and falls in a tower and doesn't require a counterweight pit. The energy is transferred from the leaf to the counterweight through a system of gears arranged in a parallelogram. The dead load of the bridge (the weight of the bridge itself) can thus be divided between two different piers, which allows the piers to be less substantial and more economical.
