Gas Pressure Regulator
Sensus produces a broad product line of Pressure Regulators - natural gas regulators, which are widely used throughout the natural gas industry. These regulators are also suitable for non-corrosive industrial gas applications such as propane regulators, butane, air, nitrogen, dry CO2, etc., contact us for additional detailed information on a particular regulator model and supply an "industry standards" regulator for your next job.

Earthquake Valve / California Shut Off Valves
Pacific Seismic Products, Inc, (PSP) has been manufacturing the California Seismic Valve also known as KOSO Valve since 1978. Serving residential, commercial, and industrial uses, over 180,000 KOSO automatic shut-off valves have been installed in California over the last two decades...
Pacific Seismic / California Seismic Valves / KOSO Earthquake 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.
These seismic valves do not use any source of internal or external electrical power. They are designed to remain closed until manually reset. 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.
Valves consist of a unique arrangement that swings closed when the acceleration-sensitive triggering mechanism is activated by a sudden motion, such as an earthquake. 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 ball’s mass to act upon the moveable 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 viewing port is built into the valve so that the Open or Closed indicator can be seen. This permits easy determination of the trip mechanism’s status.
