With their durable construction and superior chemical resistance, Our FlowBiz PTFE Lined Diaphragm Valves are trusted by chemical processing, pharmaceuticals, and water treatment industries.

Features Of PTFE Diaphragm Valves

The lining offered PTFE / FEP / PFA / PVDF. The thickness of the lining is between 3.5 to 6 mm.
The lining resins are from renowned manufacturers like DuPont, Daikin, and GFC.
Virgin PTFE, FEP, and PFA to withstand temperatures from -20 C to +240 C.
Anti- Static lining is available on request.
The valve outer body is offered in Stainless Steel 316 and mirror polished.

Advantages of PTFE Diaphragm Valves

They can be utilized as throttling and on-off service valves.
They provide good chemical resistance.
Stem leaking is no longer an issue.
The service is bubble-tight.
Solids, slurries, and other contaminants are not trapped in pockets.
This is used to control the flow of liquids and gases.

Corrosion-Resistant Performance

Constructed with high-quality PTFE lining and a range of diaphragm materials (EPDM, PTFE, Rubber), these valves ensure excellent resistance against acids, alkalis, and other corrosive fluids. This makes them a reliable choice for industries demanding uncompromised media integrity and system longevity.

Flexible Design Options

Choose between weir type and straight-through designs with various actuation (manual or pneumatic) and mounting (horizontal or vertical) options. A wide selection of end connections-flanged, screwed, or welded-ensures compatibility with global piping standards (ANSI, DIN, BS) for versatile installation.

Easy Maintenance and Zero Leakage

Featuring a maintenance-friendly top cover (in cast iron or polypropylene) and compliant with Leakage Class VI (zero leakage), our PTFE Lined Diaphragm Valves are simple to service and maintain, reducing operational downtime and ensuring reliable sealing over their service life.

FAQ's of PTFE Lined Diaphragm Valve Manufacturer in India:

Q: How are PTFE Lined Diaphragm Valves typically used in industrial applications?

A: These valves are primarily used to control the flow of aggressive media-such as acids, alkalis, and corrosive fluids-in sectors like chemicals, pharmaceuticals, and water treatment. Their corrosion-resistant PTFE lining and leak-proof seal make them suitable for critical applications where product purity and system protection are crucial.

Q: What are the benefits of choosing this valve with PTFE lining and diaphragm material options?

A: PTFE lining provides robust corrosion resistance, extending valve lifespan while minimizing maintenance. Different diaphragm materials (EPDM, PTFE, Rubber) allow users to select the best fit for their media type, enhancing chemical compatibility and reliable performance.

Q: When should I select a weir type versus a straight-through design?

A: Weir type designs are best suited for controlling corrosive, abrasive, or thick media with minimal sedimentation, while straight-through versions are ideal for services requiring minimal pressure drop or handling slurries. Selection depends on process requirements and fluid characteristics.

Q: Where can these PTFE lined diaphragm valves be installed?

A: The valves can be mounted in either horizontal or vertical pipeline orientations. Their versatile end connections-flanged, screwed, or welded-comply with ANSI, DIN, and BS standards, allowing installation across a wide range of systems.

Q: What is the typical process involved in maintaining or servicing these valves?

A: Maintenance is straightforward due to easy-access top covers made of cast iron or polypropylene. Regular inspection involves checking the diaphragm and PTFE lining condition, ensuring zero leakage, and adhering to recommended hydrostatic test procedures for maximum reliability.

Q: What leakage class do these valves comply with, and what does that mean for end users?

A: These valves meet Class VI leakage standards, ensuring zero leakage performance. For end users, this translates into enhanced operational safety, product purity, and compliance with stringent quality standards in fluid management.
