The main parameters of electric valve

Wuxi east technology co. , LTD. Is a collection of the control valve industry manufacturing, development, production, assembly, sales and service in the integration of science and technology enterprises, professional research and development of electric valve, pneumatic valves, hydraulic valves, pneumatic actuators and various kinds of complete sets of pneumatic valve. Our company produce all kinds of pneumatic ball valves, butterfly valves, plug valves, regulating valve, gate valve, globe valve, flat gate valve and pneumatic device or valve products. ( 1) Vacuum valve: refers to the working pressure is lower than the standard atmospheric pressure of the valve. ( 2) Low pressure valve: refers to the nominal pressure PN 1 or less. 6 mpa. ( 3) Medium pressure valve: refers to the nominal pressure PN to 2. 5Mpa、4. 0Mpa、6. 4 mpa. ( 4) High pressure valve: refers to the nominal pressure PN to 10. 0Mpa～80. 0 mpa. ( 5) Ultrahigh pressure valve: refers to the nominal pressure PN 100 or higher. 0 mpa. According to the working temperature: ( 1) Cryogenic valve: in the work of medium temperature t< Valves - 101 ℃. ( 2) Valve: under normal temperature in the working temperature of medium - 29 ℃ & lt; t< The valve of 120 ℃. ( 3) Medium temperature valve: in the working temperature of 120 ℃ of medium & lt; t< The valve of 425 ℃. ( 4) High temperature valve, in the work of medium temperature t> The valve of 425 ℃. According to the drive mode: according to the drive mode can be divided into automatic valve, power driven valve and manual valve class.
