PTFE Lined Actuated Butterfly Valves

PTFE Lined Actuated Butterfly Valves by TTV offer superior resistance in highly corrosive environments while meeting food-grade standards. The wafer and lugged patterns incorporate a PTFE seal extending to the valve body for ideal flange sealing and cross-contamination prevention. Available in stainless steel or ductile iron, they support Actreg, Hytork, Air Torque, and other actuators across sizes DN40-DN300. Applications include chemical, pharmaceutical, petrochemical, corrosive, food, beverage, water, and vacuum industries.

PTFE Lined Wafer Actuated Butterfly Valves

The TTV Wafer Pattern Full PTFE Lined Actuated Butterfly Valves are primarily utilised in highly corrosive environments that demand superior material resistance and compliance with food-grade or cleanliness standards. The Wafer Pattern concentric design incorporates a non-toxic PTFE internal seal, which partially extends to the valve's outer body for an ideal seal with counter flanges. This design eliminates any risk of cross-contamination while ensuring excellent chemical and solvent resistance with complete insolubility up to 300°C.

PTFE Lined Lugged Actuated Butterfly Valves

Certain valves are so advanced that they can endure even the harshest environments. A prime example is TTV's PTFE series of lugged butterfly valves, developed over years of research in collaboration with chemical manufacturers handling aggressive fluids. Lugged butterfly valves are widely used in the chemical industry and can be installed on either side of a pipeline, enabling maintenance on one side without disrupting the entire system. This feature is particularly crucial when pressure remains in one section of the line.

Actuators: Actreg, Hytork, Air Torque, Elomatic, Koei UNIC, Bettis, Ventus, J-J, & Festo
Size Range: DN40-DN300 (1 1/2"-12")
Body Materials: GJS500-7 Ductile Iron Rilsan Coated
Applications: Chemical, Pharmaceutical, Petrochemical, Corrosive, Food & Beverage, Water, Vacuum

Stainless Steel PTFE Lined Wafer Actuated Butterfly Valves

The Wafer Pattern TTV Stainless Steel Actuated Full PTFE Lined Butterfly Valves provide corrosion resistance and a food-grade solution comparable to the standard valve, while also offering external protection. This protection is suitable for corrosive environments and wash-down requirements. The Stainless Steel Full PTFE Lined Butterfly Valve features FDA-approved materials and, for applications demanding abrasion resistance, is available with a UHMWPE (Ultra-High-Molecular-Weight-Polyethylene) option. This variant offers a reliable choice for applications requiring enhanced durability.

Actuators: Actreg, Hytork, Air Torque, Elomatic, Koei UNIC, Bettis, Ventus, J-J, & Festo
Size Range: DN40-DN300 (1 1/2"-12")
Body Materials: CF8M Stainless Steel
Applications: Chemical, Pharmaceutical, Petrochemical, Corrosive, Food & Beverage, Water, Vacuum

Frequently Asked Questions

An actuated butterfly valve is a type of quarter-turn valve that uses an actuator to control the flow of fluids or gases. The actuator can be electric, pneumatic, or hydraulic and automates the operation of the butterfly valve, providing precise and consistent flow control.

A lugged actuated butterfly valve has threaded inserts (lugs) on both sides, allowing it to be used in systems where downstream piping can be removed without affecting the upstream side. This feature makes maintenance easier and allows for dead-end service.

A wafer-style actuated butterfly valve is designed to fit between two flanges and is held in place by bolts that surround the valve body. This design is compact and lightweight, making it ideal for systems where space is limited.

A double-flanged actuated butterfly valve features flanges on both ends, providing a secure connection to the pipeline. This design is especially beneficial in high-pressure applications or when frequent maintenance requires the valve to be removed easily.

Actuated butterfly valves are commonly used in industries such as water treatment, chemical processing, oil and gas, power generation, food and beverage, and HVAC due to their reliable flow control and automation capabilities.

Butterfly valves can be equipped with electric, pneumatic, or hydraulic actuators. Electric actuators are suitable for precise control, pneumatic actuators are ideal for fast operation, and hydraulic actuators are best for high-torque applications.

Key benefits include automated flow control, compact design, cost-effectiveness, and versatility in handling various fluids. Their low-pressure drop and quarter-turn operation make them ideal for on/off and throttling applications.

To select the right size, consider the flow rate, pressure rating, and pipeline diameter. Ensure the valve's Cv (flow coefficient) aligns with your system's flow requirements, and consult manufacturer guidelines for accurate sizing.

Yes, actuated butterfly valves can handle high temperatures with the appropriate choice of materials. For instance, valves with stainless steel bodies and high-temperature seals (like PTFE or Viton) can withstand temperatures up to 400°C.

Routine maintenance includes regular inspection for wear and tear, checking for leaks, lubricating moving parts, and ensuring the actuator functions properly. Replace worn-out seals and gaskets to maintain optimal performance.

Yes, actuated butterfly valves are suitable for throttling applications due to their ability to control the flow precisely. However, ensure that the valve is designed and rated for throttling to prevent damage to the disc or seat.

Actuated butterfly valves should comply with standards such as API 609, ISO 5752, ASME B16.34, and AWWA C504. Additionally, valves used in food, pharmaceutical, or chemical industries may need to meet FDA or specific industry standards.
