Flanged PSP/Koso Earthquake Valves

These valves are earthquake-sensitive gas shut-off valves. PSP/Koso earthquake valves are intended to close in the event of an earthquake to prevent gas flow into a structure where earthquake damage may have occurred. This will greatly reduce potential risk of explosion or fire due to loss of gas line integrity or uncontrolled flow of gas after a major earthquake. In event of a damaging earthquake, where gas lines can break, valve automatically shuts the flow off thus, Protecting your family and property by greatly reducing the potential risk of explosion or fire due to loss of gas line integrity or uncontrolled flow of gas. Features: No magnets used to attract debris and interfere with operation. No internal or external source of electrical power needed. Ball used for actuation NOT! for sealing of flow line. Easy Manual reset! All rubber used in unit is the same as used by gas companies as their regulators. This technology has been used for many years without repercussions. Listed
