Koso/Seismic Earthquake Valves
Pacific
Seismic/California Valves are earthquake sensitive gas shut-off
valves. They are intended to close in the event of an earthquake
to prevent gas flow into a structure where earthquake damage may
have occurred. The valve reduces the potential for fire or explosion
due to the release of natural gas into a structure where gas lines,
gas fixtures, or gas appliances. PSP's valves do not use any source
of internal or external electrical power. They are designed to
remain closed until manually reset. See more, below. |
| The
valves are intended to be mounted in the gas line upstream or
downstream of the gas-line pressure regulator and gas meter outside
the structure. These valves do not replace the manual upstream
shut-off valves provided in the gas service line. Our valve consists
of a swing check valve arrangement with an acceleration-sensitive
triggering mechanism. The trip mechanism consists of a steel ball
resting on a tapered cup-shaped support. The horizontal motion
of an earthquake causes the ball to move from the center of the
support. This allows the balls mass to act upon the movable pipe
of the trip mechanism, activating the valve and initiating closure.
Springs assist the valve- flapper to close and gas pressure assists
in holding the valve disc in the closed position. The trip mechanism
is factory set and sealed. A sight glass is provided so that the
Open or Closed indicator can be seen, and the trip mechanism status
of the valve can be easily determined.
