SII Valves – Leading the Way in High-Pressure Valve Solutions Since 1985

​

Company Overview

​Established in 1985, SII Valves has emerged as a distinguished manufacturer and supplier of IBR-approved high-pressure gate, globe, non-return valves, and a range of specialised thermal application valves. Renowned for their precision functioning and robust construction, our products have become indispensable in the boiler and turbine divisions of thermal power plants across India.

​

Pioneers in High-Pressure Valve Technology

​Our company takes pride in being the pioneer in developing high-pressure valves tailored for major power plants. Under the visionary leadership of our proprietor, who brings decades of rich industrial experience, SII Valves has built a reputation for reliability and innovation. Guided by this expertise, we have nurtured a skilled team dedicated to supporting our growth and consistently meeting our targets.

​

Customisation and Customer Commitment

​We understand that every client has unique requirements. Therefore, we offer valves in various specifications—size, design, and type—to suit specific customer needs. Our experts ensure that every product is meticulously packaged using quality materials. We are committed to delivering consignments within the shortest possible lead times and at competitive prices, helping us establish a wide client base throughout India.

​​

Manufacturing Excellence

​For over two decades, SII Valves has consistently produced high-performance products using state-of-the-art equipment, robust processes, and a dedicated workforce. Our focus on 100% compliance with customer and industry standards, on-time delivery, and sustainable manufacturing practices has set us apart in the industry.

​​

Digital Innovation in Manufacturing

​Our manufacturing complexity is managed through a proprietary digital platform, ensuring full visibility and punctual delivery. Major valve components are barcoded upon receipt, and all manufacturing instructions—including bill of materials, machining, assembly, testing, and packing—are sourced from our company-wide ERP system, guaranteeing error-free production. This digital approach also enhances project management and traceability.

​​

When a valve is ready for dispatch, all relevant information and reports—cross-referenced to the valve’s serial number—are transferred to an RFID tag attached to the valve. This enables installation, operation, and maintenance information to be instantly accessible, literally at your fingertips.

​​

Addressing Power Plant Challenges

​Power plants present unique operational challenges, and SII Valves offers a portfolio of high-performance solutions designed to meet these demands:

• Pressure-seal valves in ASME classes up to 4500, witnessed by IBR and global certification agencies

• Valves manufactured in high alloys such as C12A and F91

• Valves for intermediate pressure classes
