PFA Butterfly Valve for Chemical Service | 150LB, PTFE Seat, Gear Operated

Introduction：

Its standout feature is the specialized disc and seat combination. The disc is a **PFA-coated Stainless Steel** construction, offering exceptional resistance to a vast array of aggressive chemicals and high temperatures. Paired with a premium **PTFE (Teflon) seat**, this ensures outstanding chemical inertness and a reliable, low-friction seal. Operated by a precise **gearbox (turbine actuator)**, this valve allows for effortless manual control of larger diameters with high mechanical advantage. Available from **DN50 to DN900**, it is a versatile solution for critical shut-off and regulating duties.

Key Features & Advantages:

1. Premium Corrosion & Chemical Resistance with PFA Coated Disc & PTFE Seat

This valve is engineered for maximum durability in the most aggressive environments through its advanced material construction.

• Superior PFA-Coated Disc: The stainless steel disc is protected by a PFA (Perfluoroalkoxy) coating, which offers exceptional resistance to a wide spectrum of corrosive chemicals, acids, and solvents, while also providing excellent non-stick and high-temperature properties.

• Highly Inert PTFE Seat: The valve utilizes a full PTFE (Polytetrafluoroethylene) seat, renowned for its extreme chemical inertness, ensuring no contamination of the media and reliable sealing against even the most aggressive fluids.

• Optimal Material Synergy: The combination of the PFA-coated disc and PTFE seat creates a sealing pair with outstanding chemical compatibility, making the valve ideal for critical processes in chemical, pharmaceutical, and high-purity applications.

2. Gearbox Operation for Effortless, High-Torque Control

Designed for easy manual operation across its entire size range, especially for larger diameters.

• High Mechanical Advantage: The multi-stage worm gear operator (gearbox) provides significant torque multiplication, allowing for smooth and manageable manual operation of valves up to DN900, reducing operator effort.

• Precise Flow Regulation: The gearbox enables fine, incremental adjustment of the disc position, facilitating accurate flow control and throttling capabilities when needed.

• Secure Seating Under Pressure: The gear mechanism ensures a reliable, seated shut-off with high mechanical integrity, even under challenging high differential pressure conditions.

3. Robust 150LB Flanged (U-Type) Construction for Secure Installation

Built for strength and reliability in permanent, demanding industrial installations.

• One-Piece Flanged Body: The valve features a solid Flanged (U-Type) body with standard ANSI bolt hole drilling, providing a rigid and stable structure for pipeline integration.

• Leak-Resistant Connection: The flanged design, used with bolts and gaskets on both sides, ensures a strong, dependable, and leak-resistant connection to the piping system.

• Rated for Demanding Service: With an ANSI 150LB pressure rating, the valve is certified to perform reliably in high-pressure industrial systems and is suitable for end-of-line services.

4. Wide Size Range & Versatile Industrial Application

A single valve solution adaptable to a broad spectrum of industrial requirements.

• Comprehensive Size Availability: The valve is offered in a complete range from DN50 (2") to DN900 (36"), catering to both standard and large-scale process line requirements.

• Broad Industry Application: Its corrosion-resistant design makes it a preferred choice for critical applications across chemical processing, pharmaceutical manufacturing, pulp & paper production, and aggressive fluid handling.

• Proven & Reliable Design: The robust construction and material selection ensure long-term, dependable performance in environments where valve failure is not an option.
