About PP Lined Butterfly Valve

We are offering a wide selection of the PP Lined Butterfly Valve, which is a tool designed to control the direction and speed of the flow of chemical and fluids. Basically, it consists of a rotating plate that is attached to the transverse spindle. The valve is mounted inside a pipe in order to regulate the flow. With the application of the valve, you can effectively prevent the fluid to flow. Apart from this, the provided butterfly valve is well designed and manufactured in our state of the art production division making the best use of advanced tools and equipment, for this reason, PP Lined Butterfly Valve ensures long service life and unmatched performance.

Enhanced Chemical Resistance

The PP lined butterfly valve features a virgin polypropylene lining in all wetted parts, offering robust protection against aggressive chemicals and corrosive fluids. This design ensures longevity in challenging environments, making it ideal for chemical, water, and pharmaceutical industries. The PTFE, EPDM, or Viton seat options further improve resistance and compatibility with a variety of media.

Flexible Mounting and Actuation Options

Engineered for adaptability, the wafer type valve is compatible with ANSI 150#, DIN, or IS standard flanges. It can be actuated manually via lever or handle, or automated using pneumatic or electric actuators, making it suitable for diverse installation and control requirements. The actuator options cater to different operational environments and automation needs.

Reliability and Ease of Operation

The valves precision design ensures minimal operating torque, smooth handling, and a leak-proof seal achieved by O-ring stem sealing and high-quality lining. With zero leakage class and low maintenance requirements, it delivers reliable shut-off and control, even in applications involving toxic or abrasive process media.

FAQs of PP Lined Butterfly Valve:

Q: How does the PP lining enhance the valves performance in corrosive fluid environments?

A: The virgin polypropylene (PP) lining, applied at 35 mm thickness on all wetted valve parts, provides superior chemical resistance. It shields the internal metal surface from acids, alkalis, solvents, and toxic fluids, extending valve lifespan and improving performance in aggressive chemical processes.

Q: What are the available actuation methods for this butterfly valve?

A: This valve can be actuated through a manual lever, gear operator, or fitted with either pneumatic or electric actuators. These options offer flexibility for both manual operations and automated process control, depending on the specific requirements of your installation.

Q: When should I select a PP lined butterfly valve over a standard unlined valve?

A: A PP lined butterfly valve is recommended when handling corrosive or aggressive fluids, as encountered in chemical manufacturing, water treatment, pharmaceutical, or other industrial processes. The lining protects against corrosive attack, minimizing maintenance and prolonging service life compared to unlined valves.

Q: Where can this valve be installed within an industrial process?

A: These valves are suitable for installation in pipelines carrying corrosive or non-corrosive liquids and gases, including acids, alkalis, and solvents, within chemical plants, water treatment facilities, pharmaceutical units, and various other industrial environments requiring reliable flow control and sealing.

Q: What is the process for ensuring leak-proof operation in this valve design?

A: Leak-proof operation is achieved through O-ring stem sealing, high-quality PP lining, and precision-machined PTFE/EPDM/Viton seats. The valve is tested as per international standards API 598 and DIN 3230 to ensure zero leakage across the seat.

Q: What benefits does the epoxy-coated external body provide?

A: The epoxy-coated ductile iron or cast iron exterior shields the valve from external corrosion and abrasions, enhancing its durability in harsh environments. This coating complements the internal PP lining, offering comprehensive protection and reducing maintenance frequency.

Q: How do I select the correct size and pressure rating for my application?

A: Valve sizing typically ranges from DN40 to DN300 (1" to 12"). For optimal performance, consult system requirements and match the valve pressure class (up to PN10/10 Bar). Higher pressure applications may require tailored solutions; our technical team can provide guidance for unique needs.
