Ductile iron ball valve
DN50-200
Ductile iron rotary cut-off valve relies on the rotation of a ball with a through-hole to achieve the connection and disconnection of pipeline media. It is divided into two mainstream structures: floating ball and fixed ball, with soft seal and hard seal options. It can be equipped with manual, electric, and pneumatic actuators and is widely used in pipeline systems such as water supply and drainage, gas, petrochemical, HVAC, food and medicine, and sewage treatment. It is used to cut off and conduct media, and some V-shaped ball valves can be used for flow regulation.Main technical parameters• Nominal diameter: DN15~DN300 (expandable to DN1000)• Nominal pressure: PN16, PN25, PN40, PN63; American standard Class150-Class600Valve body material: WCB carbon steel, 304 stainless steel, 316L stainless steel, fluorine lining, cast iron, etc• Ball material: 304, 316L, sprayed hard alloy, tungsten carbideSealing materials: PTFE PTFE, PPL, FKM fluororubber, EPDM EPDM, Stellite alloy (hard seal)• Operating temperature: Soft seal -20 ℃~200 ℃; Hard seal -29 ℃~425 ℃• Connection methods: flange, internal thread, clamp, welding• Drive mode: manual handle, pneumatic, electric, hydraulicApplicable media: water, air, natural gas, oil products, steam, acid and alkali corrosive media, etcExecution standards: GB/T 12224, JB/T 9092 pressure test standardsProduct advantages1. Extremely low flow resistance and strong flow capacity: The full bore ball valve has a straight channel, low flow resistance coefficient, low pressure loss, suitable for high flow conveying conditions, and good energy-saving effect.2. Fast opening and closing, easy operation: only rotate 90 ° to fully open/close, fast opening and closing, low torque, adaptable to automatic remote control, no impact on the switch.3. Excellent sealing performance, bidirectional sealing: The soft seal adopts PTFE self-lubricating sealing surface, which is reliable and can achieve zero leakage; Hard sealing is resistant to high temperature and pressure, erosion, and the sealing force automatically increases with the increase of medium pressure.4. Simple structure and long service life: With a small number of parts, the friction between the ball and the sealing surface is low, making it wear-resistant and resistant to jamming. It is suitable for corrosive and low boiling point media, and has a high switch cycle life.5. Flexible installation and easy maintenance: can be installed in any direction, the valve seat sealing ring is easy to disassemble and replace, and the maintenance cost is low.6. Wide adaptability to working conditions: The material selection range is rich, which can meet complex working conditions such as low temperature, high temperature, high pressure, strong corrosion, flammability and explosiveness.Applicable scenariosCutting and control of fluid pipelines for municipal water supply, gas pipelines, chemical acid and alkali pipelines, heating steam, oil transportation, pure water equipment, environmental wastewater treatment, food and pharmaceutical industries, etc.
