About PTFE Lined Butterfly Valve Manufacturer in India

It is particularly suitable for corrosive duties like acids and applications where conventional rubber seats like EPDM and NBR would not be appropriate.

Available with a Pneumatic or Electric Actuator and a range of additional accessories such as a switch box, solenoid, air-filter regulator, and 4-20mA Electro-Pneumatic Positioner.
It is fully assembled and tested.

Suitable for various applications, offering durability, reliability, and cost-effective alternative to ball valves. It is ideal for corrosive duties like acids and applications where conventional rubber seats like EPDM and NBR are incorrect.

What material is used for the butterfly valve liner?

The most common lining material on butterfly valves isPTFE (polytetrafluoroethylene). PTFE-lined butterfly valves are usually more durable than non-lined ones as they offer excellent resistance to corrosion, abrasion, erosion, wear, and tear due to their chemically inert nature.

Applications Of PTFE Lined Butterfly Valve

Butterfly valves are used in diverse industries and applications such aspharmaceutical, chemical, oil, food, water supply, wastewater treatment, fire protection, gas supply, fuel handling, and sanitary fittings. Butterfly valves for water are used as control valves in pipelines to shut off water flow.

Types

Lugged Pattern PTFE Lined Butterfly Valves
Double Flanged PTFE Lined Butterfly Valves
Concentric PTFE Lined Butterfly Valves

Superior Chemical Compatibility

Featuring an internally lined seat of virgin PTFE, these butterfly valves can withstand exposure to a wide range of corrosive chemicals, aggressive media, and process fluids. This ensures extended service life and reduced maintenance in industries like pharmaceuticals, chemical processing, and water treatment.

Tailored to Your Requirements

Available with lever, gear, electric, or pneumatic actuators, these valves can be customized for diverse industrial setups. Options in body, disc, and shaft materials, complemented by advanced coatings, allow selection suited to unique applications, working environments, and media types.

Built to Highest Standards

Manufactured and tested as per API 609 and BS 5155, each valve conforms to rigorous quality control. Face-to-face dimensions, hydrostatic testing (1.5 times working pressure), and a leakage class of Class VI all ensure maximum safety, reliability, and worldwide interoperability with international pipeline systems.

FAQs of PTFE Lined Butterfly Valve Manufacturer in India:

Q: How are PTFE lined butterfly valves used in industrial applications?

A: PTFE lined butterfly valves are commonly deployed in industries where control and isolation of corrosive chemicals, water, or gases are required. They are frequently employed in pharmaceuticals, water treatment plants, petrochemical processing, and food industries due to their robust chemical resistance and clean operation.

Q: What materials are used in the manufacturing of PTFE lined butterfly valves?

A: These valves incorporate a range of body materials such as cast iron, ductile iron, carbon steel, or stainless steel. The disc can be made from stainless steel (SS304/SS316), Alloy 20, or Hastelloy-C, while shafts are crafted from SS304 or SS316. Virgin PTFE is used for the seat to ensure high chemical compatibility.

Q: When is it recommended to use a PTFE lined butterfly valve instead of a standard valve?

A: Use a PTFE lined butterfly valve when the media involves corrosive chemicals, aggressive liquids, or when a contamination-free flow path is critical. The PTFE lining prevents corrosion and extends the valves service life in environments where metals alone would degrade quickly.

Q: Where can PTFE lined butterfly valves be installed?

A: These valves are suitable for installation in pipeline systems within pharmaceutical, chemical, petrochemical, food, water treatment, and general process industries. Their versatile connection optionsflanged, wafer, or luggedfacilitate easy integration into different piping standards worldwide.

Q: What is the process for selecting the right PTFE lined butterfly valve for my system?

A: To choose the appropriate valve, consider your applications pressure (up to 16 bar), temperature range (-20C to +180C), required port size (40mm to 600mm), compatible connection standard (ASA 150, DIN, or JIS), and operation mode. The desired materials for body, disc, and shaft, as well as the liner, must also be matched to the specific media and environmental conditions.

Q: How do the different operations (manual, pneumatic, electric) affect the valves functionality?

A: Manual operation with a lever or gear is ideal for straightforward, infrequent control, while pneumatic and electric actuators enable remote or automated operation, enhancing precision, safety, and process efficiency in larger or more complex systems.

Q: What benefits do PTFE lined butterfly valves offer over unlined alternatives?

A: Compared to unlined valves, PTFE lined butterfly valves offer vastly superior resistance to corrosive and abrasive substances, delivering longer life, fewer leaks (Class VI tightness), reduced downtime, and a lower risk of media contaminationmaking them highly advantageous for sensitive or harsh fluid processes.
