Worm gear steel lined PTFE butterfly valve

Worm gear steel lined PTFE butterfly valve

Product parameters

FEP lined butterfly valve/gear operation/handle specifications FEP, PFA, PCTFE, PTFE, PO lined butterfly valve (lined valve) is suitable for various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, as well as various organic acids, strong acids, and strong oxidants

The clamp type lining butterfly valve and the clamp type anti-corrosion fluorine butterfly valve are integrated with a two-piece valve body, valve seat, and valve body lining.

When the valve is in operation, only the plastic valve seat and lining plastic butterfly plate come into contact with the medium. The product can withstand corrosion from other media except for molten alkali metals and fluorine elements. The valve stem and valve disc (forging) are integrated, and the lining is evenly coated on a surface layer. The inner surface of the valve body channel is smooth, with low fluid resistance, high CV value, strong flow capacity, moderate torque, and a four stage sealing structure. The sealing surface is matched with an elastic liner, and the valve seat is made of heat-resistant SI rubber to achieve no medium leakage.

Chinese lined clamp butterfly valve manufacturers produce domestically produced anti-corrosion butterfly valve types, and lined clamp butterfly valves are the cheapest. The valve body is usually made of cast steel material.

The lining material is chosen by the customer, and the opening device is diversified. The handle, gear operation, pneumatic, and electric all work because the upper flange connection plate complies with ISO 5211.

Butterfly Valve FAQs

01 Which butterfly valve seat design should be used?
Common designs include resilient seats and metal seats. Resilient-seated valves are generally used for water, air and low-leakage services at moderate temperatures. Metal-seated valves are selected for higher temperature, pressure or erosive industrial media. The final choice depends on the medium, temperature, pressure and required leakage class.
02 How do wafer, flanged and lug butterfly valves differ?
Wafer valves are compact and require little installation space. Flanged valves provide a stable pipeline connection for larger sizes or higher pipe loads. Lug valves can facilitate one-sided removal and maintenance. Selection depends on the piping standard, space, size and maintenance method.
03 Should a butterfly valve use pneumatic, electric or manual actuation?
Manual or gearbox operation suits local isolation. Pneumatic actuators provide fast response for frequent operation and hazardous areas. Electric actuators support remote control and modulation. The actuator must be sized for valve size, differential pressure, torque and control signal.
04 Which operating data are required for butterfly valve selection?
Provide the medium, design temperature, design pressure, nominal size, connection standard, body and seat materials, leakage class, flow direction, operating frequency, actuation method and any enclosure or explosion-protection requirements.
