Valpes Actuated PTFE Seat Lugged Butterfly Valves

Valpes actuators support 90°, 180°, and 270° operations, allowing for diverse control options depending on the application requirements. Fully Lugged Type Ductile Iron Butterfly Valves with PTFE seats find application in piping systems where a dead end service valve is required or in situations where routine or anticipated disconnection of the pipe on either side is necessary for maintenance or installation.

Frequent Interrogation

PTFE seats provide superior chemical resistance and can handle higher temperatures, making them ideal for aggressive media where EPDM or NBR seats would degrade.

A lugged butterfly valve design allows the valve to be bolted directly between flanges, enabling isolation of one side of the pipeline without disturbing the other — perfect for maintenance and shutdown systems.

Yes. The PTFE seat and corrosion-resistant construction make them an excellent choice for chemical plants, laboratories, and process industries handling aggressive fluids.a

Yes, modulating control versions are available with 4–20 mA or 0–10 V input signals, allowing precise adjustment of valve position for accurate flow control.

Typically, the body is cast iron or stainless steel, while the disc is stainless steel or PTFE-coated for added chemical protection and sealing integrity.

Yes, the PTFE seat and compatible body materials make them suitable for corrosive gases, acids, and solvents, provided system pressure limits are observed.

Yes. All Valpes electric actuators are IP67-rated, ensuring full protection against dust and water ingress, making them suitable for both indoor and outdoor installations.

Absolutely. ATEX-rated Valpes actuators are available for hazardous environments where explosion-proof equipment is required, ensuring compliance and operator safety.

These valves are designed for low maintenance operation. Routine checks of the actuator seals, electrical connections, and valve seat condition are recommended to ensure smooth performance and long service life, especially in demanding chemical or process environments.
