Description
Technical Specifications
SPECS Bolted Bonnet Forged Gate Valves are suitable for small-diameter pipelines of Class 150 ~ 2500 and operating temperature of -29 ~ 425°C (carbon steel) or -29 ~ 500°C (stainless steel). Forged steel Gate Valves are used to shutoff or connect the medium in the pipeline. Different materials are selected, which can be respectively applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media .
