FEP, PFA, PCTFE, PTFE, PO wafer type lined butterfly valve (lined valve) requires compatibility confirmation for the actual medium, concentration, operating conditions and all wetted components. A lining-material listing does not establish suitability for every concentration of the acids or oxidizing media mentioned here.
Gear Operated wafer type lined butterfly valve
The lined wafer butterfly valve uses a two-piece body with an integrated seat and body lining.
valve is working, only all plastic seat and lining plastic butterfly plate and the media contact, chemical compatibility must be confirmed for the actual medium, concentration, temperature, pressure and all wetted components; the lining does not establish universal resistance to every other medium, 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, with shell and seat leakage performance to be confirmed against the specified acceptance criteria and test conditions for the selected assembly.
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。
Worm gear/handle clamp lined butterfly valve
Frequently Asked Questions
Which lining is actually supplied with the FEP-listed wafer valve?
The page discusses several lining alternatives. Require the selected lining grade, disc covering and seals to be identified on the quotation and order documents and checked against your process conditions.
Can I select a handle rather than a worm gearbox?
State the required operating method, selected size and duty and request confirmation of the complete assembly. Also check lever or handwheel access using the selected drawing.
Does the general acid-resistance description cover my actual chemical mixture?
Do not assume universal compatibility. Provide all chemicals, concentrations, operating conditions and cleaning agents and request a review of every wetted component in the selected valve.
