Fully lined EPDM rubber lug butterfly valve

Fully lined EPDM rubber lug butterfly valve

Product parameters

Fully lined EPDM rubber lug butterfly valve is a corrosion-resistant butterfly valve. Butterfly valves use EPDM or NBR valve plates, which can effectively prevent the corrosiveness and permeability of certain media. Butterfly valves can also be equipped with worm gear transmission devices, pneumatic actuators, and electric actuators.

EPDM lined lug butterfly valve EPDM valve plate/EPDM valve seat/handle driven EPDM fully lined lug butterfly valve is mainly used for applications in sewage pipelines and some low corrosive media. Compared with PTFE lined butterfly valves, the price will be cheaper and the cost-effectiveness will be higher

Valves can adopt ANSI Class 150 flange connection standard, JIS 10K flange connection standard, and EN PN10/16 flange connection standard. According to customer needs, the driving device can be worm gear transmission, pneumatic actuator, electric actuator, etc.

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.
