Butterfly valve

  • Triple Offset Butterfly Valve
    Triple offset butterfly valve is the best open and closure device in the pipeline and leads the trend of open and closure devise,its main features are quick open and closure,Triple eccentric metal butterfly valve can easily achieve by rotating 90C .Triple eccentric butterfly valve enables automated remote control;simple structure,small size,light weight,small installation space:metal seated and soft seated structure can be used in a variety of conditions,Triple eccentric butterfly valve has good sealing performance,long service life,fire safe design,full of open condition enables small flow resistance,and half open condition,Triple eccentric butterfly valve allows flexible flow control,low operating torque valve,simple and quick operation.
  • Concentric Resilient Seat Butterfly Valve
    Concentric Resilient Seat Butterfly Valve has very strong corrosion resistance and erosion resistance capability with long service life. The disc material is duplex stainless steel, such as 2205, 1.4529 and so on, which have extremely strong resistance to chlorine ion corrosion (resistance to chloride ion 40000ppm), high surface hardness and strong comprehensive mechanical properties, especially for slurry application. Austenitic stainless steel can also be used according to the working condition. The disc and resilient rubber sealing combination realizes bubble tight sealing. The connection is wafer type.
  • ANSI/DIN Ventilation butterfly valve for Fume gas
    Ventilation butterfly using the same material into the valve body seals, the applicable temperature varies depending on the selection valve, nominal pressure ≤ 0.6MPa, generally applicable to industry, metallurgy, environmental protection, regulating media flow conduit for ventilation purposes, its main features is:1. Novel design, reasonable, unique structure, light weight, open and close quickly.2.Operating torque is small, easy to operate, smart victory.3. Using materials adapted to meet different medium temperature and corrosive media.
  • GI/GIQ/GIDSeries Pneumatic High Vacuum Butterfly Valve
    Vacuum butterfly valve has high flow conductivity for turn on or cut off the vacuum airflow. The applicable media is air and non-corrosive gas. In order to get the control automatically.
    a) GI type manual or worm gear operated valve has multiple open and close locking function, angle degree of the plate is 0º-90º.
    b) GIQ type pneumatic vacuum butterfly valve operated by compressed air and through electromagnetic device to change the airflow control the actuator rotated then drive the valve open or closed. Actuator can be double acting and single-acting spring return type, also can driven intelligent positioner through the external input signal to control the pneumatic driving.
    c) GID series electric butterfly valve operated by electrical device to drive the valve plate to open or closed. Electric actuator is passive contact type as factory setting, can be optional on-off and regulating control type to achieve adjusting control.
  • wafer type Full FPA /F46/ PTFE lined butterfly valve
    Wafer Style Split Body Teflon / PTFE Lined High Performance Concentric Butterfly Valves Resilient Seated and Half or Fully Lined with two-piece body design and locked-in PFA liner fully encapsulates the disc, ISO mounting pad for actuation, bi-directional sealing, lining material is available for PTFE/PFA/FEP/ETFE/PO/PP etc, wafer or lug style for 150 class flange, F46 Lined Wafer Butterfly Valves features ease of maintenance, repeatable on-off, long life durability. Teflon Lined Wafer Butterfly Valve .
