Superior Chemical Resistance for Industrial Needs

This lined check valve employs a specialized PTFE, FEP, or PFA lining, rendering it resistant to a wide spectrum of aggressive chemicals and acids. Designed for fluid integrity in corrosive environments, it is ideal for chemical processing, pharmaceutical lines, and acid transfer applications. The rugged construction and advanced lining guarantee safe, ongoing operation even under challenging conditions.

Compliance with Global and Industry Standards

Each valve adheres to renowned global specifications, including ANSI B16.5 and DIN standards for end connections, and ASME B16.10 or DIN EN 558 for face-to-face dimensions. Rigorous inspections and testing (API 598/DIN 3230) ensure both safety and reliability, while bubble-tight sealing (Class VI) is achieved for zero operational leakage. This makes the valve a trusted choice for critical industrial operations.

Durability and Performance You Can Trust

The combination of an epoxy-coated exterior, sturdy stainless steel pin, and a seamless fluoropolymer lining ensures long-lasting resilience. Designed for horizontal installation, this valve is simple to use, operates automatically by flow direction, and maintains low cracking pressure. Its broad pressure class compatibility and size range enable flexible integration into new or existing systems.

FAQs of Lined Check Valve:

Q: How does the lined check valve maintain superior chemical resistance in corrosive environments?

A: The valve incorporates a seamless PTFE, FEP, or PFA lining across its wetted surfaces, providing a robust barrier against corrosive fluids and aggressive chemicals. This advanced lining prevents direct contact between the process media and the valve body, significantly extending the valves lifespan and ensuring reliable service in harsh industrial conditions.

Q: What standards does the valve comply with for installation and testing?

A: The lined check valve features end connections conforming to ANSI B16.5 or DIN PN10/PN16, and face-to-face dimensions according to ASME B16.10 or DIN EN 558. For quality assurance, every valve is tested for both hydrostatic and pneumatic performance as per API 598 or DIN 3230 standards, guaranteeing bubble-tight sealing (Class VI equivalent).

Q: When and where should this valve be installed for optimal performance?

A: This check valve is recommended for horizontal installations to ensure proper functioning and lifespan. It is best suited for environments handling corrosive liquids or gases, such as chemical plants, pharmaceutical manufacturing lines, and acid transfer systems.

Q: What is the process for ensuring zero leakage in these lined check valves?

A: Each valve undergoes a rigorous 100% hydrostatic and pneumatic inspection, as well as leakage testing according to API 598 or DIN 3230 standards. The use of PTFE, FEP, or PFA linings along with precision disc and sealing surfaces results in bubble-tight closure, preventing any fluid or gas from leaking past the valve.

Q: How does the valve operate, and does it require manual intervention?

A: The valve operates automatically in response to the flow direction. Its swing-check design opens with forward flow and closes to prevent backflow, requiring no manual operation or external control system. This enhances reliability and reduces maintenance requirements in continuous process lines.

Q: What are the key benefits of choosing this lined check valve for industrial applications?

A: Choosing this valve offers enhanced chemical resistance, exceptional durability due to robust construction and epoxy coating, and reliable leakage performance. Its compatibility with international standards allows seamless integration, and its automatic operation supports process safety in diverse industrial applications.
