Gate Valve Manufacturers in India

IPC manufactures the full range of Gate Valve, which are ideal for bi-directional, low friction flow and shut-off as per international standards. Due to the flow characteristics of the wedge to seat design, Gate Valves are always operated in the full close or full open position.

IPC manufactures wide range of sizes in gate valve right from 2” to 24” (DN- 50 to DN -600) and pressure rating ranges from ASME class 150 through 4500. Higher pressure rating and bigger sizes can also be provided.

Frequently Asked Questions

Why are gate valves so common, and how do they work?

Think of a gate valve as the industrial world’s basic on/off switch for fluid flow. It uses a solid / flexible (or wedge) that lifts completely out of the pathway, allowing for full, unobstructed flow with very little pressure drop when open. IPC specializes in manufacturing these reliable, simple-to-operate valves for a wide range of standard and demanding applications.

What makes IPC a trusted gate valve manufacturer?

Our trust comes from dedicated process expertise and scale. We combine proven design standards (like API 600 and ASME B16.34) with in-house manufacturing control. Operating from a large facility with over 120 specialists, we ensure every valve from raw material to final testing meets high standards of reliability for our customers.

What types of gate valves does IPC offer?

We provide a comprehensive range, including the common Bolted Bonnet Gate Valve, along with Pressure Seal Bonnet designs for high-pressure systems. Our valves come in various sizes, materials (like Cast Carbon Steel, Stainless Steel, Alloy Steel), and trim options to handle different pressures, temperatures, and media types.

What exactly is a Bolted Bonnet Gate Valve?

This is a classic, robust design where the valve body (which holds the pressure) and the bonnet (the “lid” that provides access to internal parts) are sealed together by a ring of strong studs and nuts. This creates a secure, reliable seal that makes it perfect for a wide range of industrial pressures and temperatures. It’s known for its durability and ease of maintenance.

When should I choose a Bolted Bonnet design?

This is often the best choice for general industrial service across oil & gas, power, chemical, and water applications. It’s especially suitable for systems with moderate to high pressures where a leak-proof seal is critical, and where you might need to access the valve internals for inspection or maintenance over its long service life.

How do I choose the right gate valve for my application?

The key factors are the fluid type, pressure, temperature, and required size. Our team is here to guide you. We’ll ask about your specific media (water, steam, oil, corrosive chemicals), system pressure (PN ratings/Class), and connection type (flanged, buttweld) to recommend the optimal material and design from our range.
