Product name:J41H-16C globe valve
Product category:Forged steel globe valve
Information
I. overview of J41H-16C globe valves:
Flange type 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 flow, allow for adjustment and throttle custom-made. Nominal pressure 1.6MPa-16.0MPa, work temperature -29 ~ 550 degrees of petroleum, chemical, pharmaceutical, fertilizer, power industry and other working conditions on the pipeline, cut off or switch on the pipeline medium. Driving methods are manual, gear drive, electric, pneumatic and so on.
