Brass Foot Valve
Manufacturer,Stockist and Exporter of Brass Foot Valve
Sumer Metal Industries Private Limited is a leading manufacturer, supplier, and exporter of premium brass foot valves. With decades of experience in the valve industry, the company has earned a strong reputation for quality, precision, and reliability in both domestic and international markets.
Their brass foot valves are exported to Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, the USA, Canada, and various regions across Africa. This wide distribution reflects the company’s commitment to delivering high-quality products globally.
A brass foot valve is a type of check valve installed at the suction end of a pump. It prevents backflow, maintaining the pump’s prime and ensuring smooth operation of the water system.
These valves are commonly used in irrigation systems, water supply networks, industrial water systems, and marine applications. They are suitable for both domestic and commercial installations.
Sumer Metal Industries manufactures brass foot valves primarily using CW617N brass, renowned for its excellent corrosion resistance, durability, and machinability, making it ideal for long-term service in water systems.
The valve body is precision-engineered to withstand high pressures and temperature variations. The design ensures minimal water resistance while maintaining robust structural integrity.
The seat is made of Polyoxymethylene (POM) or Nitrile Butadiene Rubber (NBR). These materials provide tight sealing, ensuring no leakage during operation.
High-quality stainless steel springs (AISI 302) are used to keep the valve closed when the pump is off, preventing backflow efficiently. The spring’s durability enhances the valve’s long-term performance.
A stainless steel mesh screen is integrated to filter out debris and prevent foreign particles from entering the pump, which improves the system’s lifespan and reduces maintenance needs.
These valves operate efficiently within a temperature range of -10°C to 80°C. The standard pressure ratings are BTP: PN24 and STP: PN16, making them suitable for most water pumping systems.

Brass foot valves are available in multiple sizes, ranging from ½ inch to 2 inches, accommodating various pipe diameters and pumping requirements.
The combination of brass, stainless steel, and POM/NBR components ensures excellent resistance to corrosion from water and environmental factors, making these valves durable in both fresh and slightly saline water conditions.
CW617N brass provides a tensile strength of approximately 500 MPa, yield strength of 250 MPa, hardness of 120–160 HB, and elongation of 20–30%, offering reliability under mechanical stress.
CW617N brass corresponds to DIN CuZn39Pb3, BS CZ121, and ASTM C37700, ensuring compatibility with international standards and making it easier to integrate with existing systems worldwide.

Brass foot valves come with threaded BSPT connections, allowing easy installation without specialized tools. Their compact design ensures they fit seamlessly at the suction line of pumps.
Due to durable materials and corrosion-resistant design, these valves require minimal maintenance. Routine checks and cleaning of the mesh screen are sufficient to ensure long-term operation.
By preventing backflow, these valves improve pump efficiency and reduce energy consumption. They maintain the water column in suction lines, reducing pump wear and tear.
