The product for high-rise, high-rise building design, students used to solve high-rise building live water, fire water system, required flow, high sensitivity, low flow resistance, only back to good sealing effect, requiring the occasion does not produce water hammer. Together with the design of the product management, and long life.
This vavle is suitable on system such as petroleum, chemical industry, foodstuff, medicine, papemaking, water and electricity, shipping, plumbing, the smelting and sources of energy etc the pipe route. Can regard on gas, liquid, semifluid as well as solid powder pipes and power lines and the container of many kinds of corrosiveness and non-corrosiveness adjusts and dams a river the equipment use. Especially extensively being in high layer of building fire protection system reaches other to show in the pipes and power lines system of valve of vavle switch state.
