Description

Single Disc Check Valve – Wafer/Lug Type, API 594/6D, Class 150–900LB

The Single Disc Check Valve by TEJI is engineered for efficient non-return functionality in pipeline systems where space constraints, simplicity, and dependable sealing are paramount. Designed for horizontal or vertical installation, this valve prevents reverse flow using a swing-type, spring-assisted single disc mechanism that ensures quick response and low-pressure drop.

Constructed from a wide range of carbon steel, stainless steel, and alloy materials, the valve handles a broad spectrum of media, including water, steam, oil, nitrates, and strong oxidizing agents. Its wafer and lug body configurations offer installation flexibility, allowing the valve to be sandwiched easily between flanges without the need for extra gaskets or bolts.

Manufactured in compliance with API 594, API 6D, and ASME B16.34, this valve ensures full conformity with global industrial standards for face-to-face dimensions, pressure-temperature ratings, and inspection/testing. Its compact and lightweight structure is ideal for applications in chemical processing, power generation, petrochemical, and industrial fluid systems where backflow prevention is critical.
