Nalisha Valves And Automation Limited

The Steel Gate Valve is a robust and reliable valve designed for on/off flow control in pipelines carrying water, oil, gas, steam, and other industrial fluids. Manufactured from high-quality carbon steel or alloy steel, it offers strength, durability, and resistance to high pressure and temperature, making it suitable for demanding industrial applications.

The gate mechanism ensures full-bore flow with minimal pressure drop when open and provides a tight shut-off when closed. These valves are available in flanged, threaded, or welded end connections and can be operated manually or with pneumatic/electric actuators for automated control.

Key Features:

• Steel construction for high strength and long-lasting performance

• Gate design for full-bore flow and tight shut-off

• Flanged, threaded, or welded end options for easy installation

• Manual or actuator-operated operation

• Suitable for high-pressure and high-temperature applications

• Low maintenance with long service life

Applications:

• Oil and gas pipelines

• Chemical and petrochemical industries

• Power plants and steam systems

• Water and wastewater pipelines

• Industrial process lines

The Forged Steel Globe Valve is a high-performance valve designed for precise flow regulation and isolation in industrial piping systems.

PFA Lined Valves are specially designed valves for handling highly corrosive and aggressive chemicals in industrial piping systems. The internal surfaces are lined with PFA (Perfluoroalkoxy), which provides excellent chemical resistance, high purity, and superior thermal stability, making these valves ideal for critical chemical and process applications.

The PFA lining ensures leak-proof performance, reduced contamination, and extended service life, even when exposed to strong acids, alkalis, and solvents. These valves are available in various types such as ball, butterfly, diaphragm, and plug valves, and can be operated manually or with pneumatic/electric actuators.

Key Features:

• High-purity PFA lining for superior chemical resistance

• Suitable for handling highly corrosive and aggressive media

• Smooth internal surface to prevent buildup and contamination

• Leak-proof performance and long service life

• Available in manual, pneumatic, or electric actuation

• Offered in flanged, wafer, or lined-end configurations

Applications:

• Chemical and petrochemical industries

• Pharmaceutical and fine chemical processing

• Acid and alkali handling systems

• Water treatment and effluent plants

• Semiconductor and specialty process industries
