Truncated: such as gate valves, globe valves, plug valves, ball valves, butterfly valves, needle valves, diaphragm valves, etc. Truncated type valve, also known as closed valve, globe valve Emmett Ke valve, its role is to connect or disconnect the line of media. Check Tanggu valve plant, also known as a one-way check valve or check valve, the check valve is a kind of automatic valve Tianjin Tanggu valve, whose role is to prevent the line of medium back, to prevent reverse pump and drive motor and leak-proof container media. Pump water off the end of the valve also belongs to check class. Proof valves, valves and other accidents, the safety valve is to prevent the line or device medium pressure exceeds a predetermined value, so as to achieve security purposes. Regulating valves, throttle valves and pressure relief valve, and its role is to regulate media pressure, flow and other parameters. Press Nominal (1) vacuum valve: the working pressure below the standard atmospheric pressure valve. (2) Low pressure valve: nominal pressure PN ≤1.6Mpa valve. (3) pressure valve: PN nominal pressure is 2.5Mpa, 4.0Mpa, 6.4Mpa valve. (4) high-pressure valve: nominal pressure PN is 10.0Mpa ~ 80.0Mpa valve. (5) high pressure valve: nominal pressure PN≥100.0Mpa valve. (6) Filter: nominal pressure PN 1.0Mpa, 1.6Mpa Watts Valve is | Hubei valves | valve out of Hong Kong, the Hong Kong valve provided by the Dongguan Science and Technology Co., Ltd.
