At Krishna Industries, we supply reliable and cost-effective single plate check valves from Ahmedabad, Gujarat, specifically tailored for Indian buyers, contractors, traders, OEMs, and industrial users. This product is ideal for bulk procurement with a Minimum Order Quantity (MOQ) of 10 pieces, making it suitable for projects, resale, and industrial maintenance requirements.

This DN150 (6 inch / 150 NB) wafer check valve is widely used in water supply systems, HVAC pipelines, fire fighting lines, pump discharge lines, irrigation networks, chemical process lines, and utility piping. Its compact wafer design ensures easy installation between flanges without requiring additional support structures, saving both space and cost.

Long Introduction – Product Overview & Industry Relevance

In modern industrial piping systems, controlling the direction of flow is as important as regulating pressure and volume. A single plate check valve, also known as a wafer type non return valve, plays a vital role in ensuring that fluids move in only one direction, thereby protecting pumps, compressors, pipelines, and other critical equipment from damage caused by backflow.

The 6 inch Single Plate Check Valve DN150 offered by Krishna Industries is engineered to meet the demanding requirements of Indian industrial environments. Whether installed in municipal water distribution networks, industrial process plants, or commercial HVAC systems, this CI wafer check valve delivers dependable sealing and long service life.

This product belongs to a broader category of industrial check valves, wafer type valves, cast iron non return valves, single disc NRVs, and pump line check valves. Compared to traditional swing check valves, the single plate wafer design offers faster response time, reduced pressure drop, and a more compact footprint. These advantages make it a preferred choice for modern piping layouts where space efficiency and performance consistency are essential.

The valve body is manufactured from high-grade Cast Iron, ensuring excellent mechanical strength and vibration resistance. The Mild Steel disc provides rigidity and reliable movement under varying flow conditions, while the Nitrile (NBR) O-ring ensures tight shut-off and leak-proof sealing, especially suitable for water, air, and mild oil applications commonly found in Indian industries.

Finished in standard blue epoxy coating, the valve is protected against corrosion, rust, and environmental wear, making it suitable for indoor as well as outdoor installations. The DN150 wafer type check valve is compatible with standard Indian flange dimensions and can be installed easily without specialized tools or modifications.

As a supplier based in Ahmedabad, Gujarat, Krishna Industries understands the operational, cost, and delivery challenges faced by Indian buyers. We focus on supplying robust, field-proven valve solutions that balance quality and price, making our products ideal for government projects, private contractors, OEMs, and hardware traders across India.
