Gas Shut Off Valves
A line of Earthquake-activated gas shut off valves is available from Holdrite. Unlike other gas shut off valves, the Northridge ValveT does not have external shaft seals or internal rubber seals that may deteriorate, rupture or leak over time. The valve features a corrosion-resistant aluminum housing, a rare earth magnet and a stainless steel ball. www.holdrite.com Holdrite.
