Dual Plate Check Valve

Description

KELOR Dual Plate Check Valve – Manufacturer, Supplier & Exporter

The KELOR Dual Plate Check Valve, also known as a Double Door Wafer Check Valve, is engineered for efficient backflow prevention in modern pipeline systems. Its compact wafer-type design and spring-assisted dual plates ensure quick response to flow reversal, significantly reducing water hammer and protecting downstream equipment.

Designed in accordance with API 594, API 6D (where applicable), ASME B16.34, and international testing standards, KELOR dual plate check valves are suitable for installation between ANSI, DIN, BS, and JIS flanges. The lightweight construction reduces installation cost while maintaining excellent structural strength and sealing reliability.

The valve features two spring-loaded plates mounted on a central hinge pin. This configuration allows the plates to open smoothly with forward flow and close rapidly when flow stops, ensuring tight shut-off performance and minimal pressure loss. The short face-to-face dimension makes it ideal for space-constrained piping layouts.

KELOR manufactures dual plate check valves using high-grade materials such as Ductile Iron, Carbon Steel (WCB), and Stainless Steel (CF8 / CF8M), with elastomer and metal seat options to match diverse media and temperature requirements. Precision machining, robust springs, and corrosion-resistant coatings ensure long-term reliability even in demanding service conditions.

These valves are widely used in water distribution, HVAC systems, fire protection lines, oil & gas pipelines, chemical processing, power plants, and industrial utilities. Every valve undergoes strict quality inspection and hydrostatic testing to deliver dependable, leak-free performance.

KELOR, based in India, is committed to supplying globally competitive flow control solutions by combining engineering expertise, advanced manufacturing, and rigorous quality assurance. Bulk supply and export packaging are available on request.
