Cast steel globe valve

Product overview

Cast steel globe valves are of the rising stem type and the hand wheel rotates and rises with the stem. Cast steel globe valve opening and closing parts are cylindrical disc, sealing surface is flat or conical surface, disc along the fluid center line for linear motion. Globe valves are only suitable for full open and full close, generally do not have to adjust the flow, custom allowed for adjustment and throttling. It is suitable for cutting or connecting the pipeline medium under nominal pressure of 1.6mpa-16.0mpa and working temperature of -29-550 ℃ in petroleum, chemical industry, pharmaceutical industry, chemical fertilizer industry, electric power industry and other working conditions. The driving mode is manual, gear, electric, pneumatic and so on.
