Overview (for Model No.ZH2000-DN15):

Our ZH2000 DN15~DN20 Series Gas Valves are emergency shut-off  devices for gas pipe .It can connect with gas leakage alarm system or fire-fighting as well as other intelligent alarm terminal module to achieve shutting –off gas in time manually or automatically at distance for safety. When strong and harmful vibration occurs, valves can automatically shut-off. Resetting valves need to be operated by manual, which is required by relevant security regulation.
