Sumer Metal Industries Private Limited is a renowned manufacturer, supplier, and exporter of premium-quality Copper Stop Valves. With decades of experience in the industry, the company has established itself as a trusted name for high-performance valves used across domestic, commercial, and industrial applications.

The company exports its Copper stop valves to a wide array of countries, including Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and various regions across Africa. Their international presence is a testament to the superior quality, reliability, and compliance with global standards of their products.

Sumer Metal Industries manufactures Copper stop valves primarily using CW617N Copper (CuZn39Pb3). This high-quality Copper alloy ensures excellent corrosion resistance, durability, and the ability to handle high pressure and temperature environments, making the valves ideal for both residential and industrial pipelines.

A Copper stop valve operates by moving a disc or plug via a valve stem, which either allows or stops the flow of fluid. These valves are designed for smooth operation and minimal leakage, offering precise control over liquid or gas flow in the system.

Copper stop valves are widely used in plumbing systems, water supply networks, heating systems, oil pipelines, gas lines, and food & beverage industries. Their versatility makes them suitable for a range of industrial, commercial, and household applications.

Sumer Metal Industries offers Copper stop valves in a size range of ½" to 4" (DN15 to DN100). They are designed to withstand a pressure rating of PN16, ensuring safety and reliability in high-pressure applications.

These valves can handle temperatures from -10°C to +180°C, making them suitable for both hot and cold water systems. They are compatible with a variety of media, including water, oil, gas, and sewage.

The stop valves are available with multiple end connection options such as BSP, BSPT, NPT, flanged, and welded, allowing easy integration into different pipeline systems. This flexibility enhances installation efficiency.

All Copper stop valves from Sumer Metal Industries comply with ISO 9001, CE, and RoHS standards, ensuring that the valves meet global safety, quality, and environmental requirements.

The chemical composition of CW617N Copper used includes Copper (58–63%), Zinc (35–39%), Lead (1.5–2.5%), Iron (≤0.5%), Tin (≤0.1%), and Nickel (≤0.5%). This composition provides excellent machinability, corrosion resistance, and strength.
