Freshwater Wafer Type Butterfly Valves Easy To Install And Maintain
Wafer Type Butterfly Valve Brief introduction:
The butterfly valve is operated by the disc rotating form 0° to 90°, can be applied to cut off or regulate
the flow of medium.
The valve can be actuator by operating lever, handle wheel electric actuator or pneumatic actuator.
Widely used for potable water supply and distribution, waste water treatment, electric power plant, gas
supply, warm-air system, smelting plant, ship building, textile, petroleum, chemistry, or other light
industries.
Wafer Type Butterfly Valve Features:
⊙ Small operation torque
⊙ Easy to install and maintain
⊙ Flow pattern tend to be straight
⊙ Open-close 90° more smoothly

Features:
⊙ Professional design
When initiating the rotary opening movement the disc is off-seated after only a few
degree of opening movement and there is very little wear and tear between seat ring and disc.
⊙ Combine fastness
Stainless steel seat ring is rolled into the valve body by applying special rolling technology
when DN<1200. Ultrasonic spray applies seal of valve body when DN>1400.
⊙ Adjust tightness
Rubber sealing ring and disc can adjust tightness or softness of sealing with clamping ring, it insures
best performance of adjusting the compression of sealing.
