2 Inch Non Return Valve (NRV) – Cast Iron | Single Plate, Short Type | PN10

MOQ: 10 Nos
Supplier: Krishna Industries
Location: Ahmedabad, Gujarat, India

────────────────────────────────────────
INTRODUCTION
────────────────────────────────────────

The 2 Inch Non Return Valve (NRV) Cast Iron is a critical flow-control component widely used across Indian industrial, commercial, and infrastructure applications where backflow prevention is mandatory. At Krishna Industries, Ahmedabad, we supply robust, application-tested non return valves designed to meet Indian operating conditions, Indian pipeline standards, and Indian buyer expectations in terms of durability, pricing, availability, and after-sales confidence.

Also commonly referred to as a check valve, one-way valve, reflux valve, or single plate non return valve, this product ensures unidirectional flow of media such as water, oil, and gas while automatically preventing reverse flow that can damage pumps, pipelines, meters, and downstream equipment. Our 2 inch NRV is engineered in a single plate, short pattern design, offering compact installation, low pressure drop, and maintenance-free performance.

This valve is frequently used alongside butterfly valves, gate valves, ball valves, and foot valves in pumping systems, HVAC pipelines, fire-fighting networks, water distribution lines, industrial process piping, and utility services. Due to its compact body and lightweight construction, it is especially suitable for space-constrained installations commonly found in Indian plants, buildings, and machinery skids.

Krishna Industries positions itself as a reliable Indian supplier of non return valves from Ahmedabad, Gujarat – one of India’s largest industrial manufacturing hubs. We understand the practical requirements of Indian contractors, OEMs, traders, EPC companies, factories, and maintenance teams. Our focus is not only on specifications but also on real-world performance, consistent quality, and competitive pricing for bulk procurement.

PRODUCT OVERVIEW
────────────────────────────────────────

Product: Non Return Valve (NRV)
Type: Single Plate / Single Disc
Pattern: Short Type
Nominal Size: 2 Inch (50 mm)
Pressure Rating: PN 16
Seat Leakage: Zero Leakage, Tight Shut-Off
Mounting: Horizontal & Vertical
Operation: Automatic (No Manual Actuation Required)

This 2 inch cast iron NRV operates automatically using line pressure. When the forward flow starts, the disc opens smoothly, allowing media to pass. When the flow stops or reverses, the disc immediately closes, preventing backflow. The single plate mechanism reduces moving parts, ensuring longer service life and lower chances of failure.

────────────────────────────────────────
MATERIAL OPTIONS
────────────────────────────────────────

To suit diverse Indian industrial applications, Krishna Industries supplies this non return valve in multiple material combinations:

• MS (Mild Steel)
• Cast Iron
• Cast Steel
• Stainless Steel SS304
• Stainless Steel SS316

Material selection depends on media type, temperature, pressure, corrosion resistance, and cost considerations. For water and general utility services, cast iron is widely preferred across India due to its strength and economy. For oil, gas, or corrosive fluids, SS304 or SS316 options are recommended.

────────────────────────────────────────
MEDIA COMPATIBILITY
────────────────────────────────────────

This 2 inch NRV is suitable for handling:

• Water (Raw water, treated water, cooling water)
• Oil (Light oil, lubricating oil, industrial oils)
• Gas (Air, inert gases, compatible industrial gases)

It is commonly installed in pumping systems, compressor lines, boiler feed systems, cooling towers, fire hydrant lines, and process pipelines across Indian industries.
