Information

Detailed introduction:
Standard flange valve opening and closing parts is a cylindrical valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. Standard valve is only applicable to fully open and fully closed, generally do not have to adjust the meteor, allow for adjustment and throttle go do. Nominal pressure 1.6MPa-16.0MPa, all kinds of work conditions of pipeline Trent -29~550 DEG C in petroleum and chemical, pharmaceutical, chemical, electric power industry and so on, cut off or connected piping media. Driving methods are manual, gear drive, electric, pneumatic and so on.
