FEP, PFA, PCTFE, PTFE, PO wafer type lined butterfly valve (lined valve) is suitable for various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, Strong oxidants
Gear Operated wafer type lined butterfly valve
Wafer anti-corrosion fluorine-butterfly butterfly valve USES the points and two pieces of the valve body, valve seat and valve body Lined with integration.
valve is working, only all plastic seat and lining plastic butterfly plate and the media contact, the product can withstand “except molten alkali metals and fluorine element” the other medium corrosion, the valve stem and disc (forging) is an organic whole, Lined evenly coated on the surface of a layer. The inner surface of the valve body channel is smooth, the fluid resistance is small, the CV value is high, the flow capacity is strong, the torque is moderate, the four-stage sealing structure and the sealing surface is matched with the elastic liner seat of the temperature resistant SI rubber, so as to achieve no leakage of the medium.
China lined Wafer Butterfly Valve manufacturer
Made in China Anticorrosive butterfly valve type, lined wafer butterfly valve belongs to the most cheap, the body is usually cast steel material.
lining material by the customer to choose, open the device and diversification, Handles, Gear Operated, pneumatic, electric all work, because the upper flange connecting discs comply with ISO 5211。
