Compact Structure Flowseal Butterfly Valve Resilient Seated Butterfly Valves

General:
o Compact structure; low flow resistance; flow pattern tend to be straight; low weight; easy to install and maintain; small operation torque, open-close 90 .more smoothly. The valve can be applied to cut off or regulate the flow of media. Valve can be actuated by operating lever, handle wheel, electric actuator or pneumatic actuator.
Professional design:
o Disc and stem connected without pin bolts, which insure no inner leakage.
O The sealing surface of disc is spherical shaped, promote the sealing capacity and increase the durability, remain no leakage after opening and closing over 50,000 times.O Upon request, disc can be coated with Nylon or F46.
Excellent corrosion protection:
o Outside electrostatic epoxy resin powder coating.
Reliable health nature:
o Epoxy resin powder is up to the health standard GBT17219 -1998
Scope of application:
o Potable water supply and distribution, waste water treatment, electric power plant, gas supply, warm-air system, smelting plant,ship building, textile or other light industry.
