Based in Ahmedabad, India, Forex Valves supplies flow-control products to domestic and international customers. Our manufacturing approach focuses on appropriate material selection, dimensional accuracy, pressure testing and quality inspection to support dependable performance in demanding operating environments.

Our range can be considered for applications involving water, chemicals, hydrocarbons, steam, air and other industrial fluids. Product selection depends on factors such as service conditions, valve size, pressure class, material, end connection and installation requirements.

Industrial Non Return Valve Solutions

Non-return valves, also known as check valves, are designed to permit flow in one direction while restricting reverse flow. They can help protect pumps, compressors, pipelines and other connected equipment from unwanted backflow and pressure-related operating conditions.

Forex Valves offers different designs to suit varying pipeline configurations, operating pressures, temperatures and fluid characteristics. The appropriate design should be selected according to the actual service conditions of the system.

High Pressure Check Valve

High-pressure check valves are used in piping systems where pressure resistance and dependable reverse-flow prevention are important. They can help protect pumps, compressors and connected equipment from changes in flow direction and pressure conditions.

Material selection depends on the pressure rating, process medium, temperature and other service requirements. These valves may be used in process plants, power facilities, oil and gas installations and other heavy-duty industrial systems.

Wafer Type Check Valve

Wafer-type check valves provide a compact solution for piping systems where installation space and overall equipment weight are important considerations. Their compact configuration makes them suitable for a variety of process and utility piping applications.

Typical applications can include water treatment, chemical processing, pharmaceutical facilities, power generation and general industrial services, subject to the required material and operating conditions.

Lined Check Valve

Lined check valves are designed for applications where the process medium may be chemically aggressive or corrosive. An appropriate lining can provide additional protection to internal surfaces and help improve service life under demanding operating conditions.

These valves may be suitable for chemical processing, water treatment and other applications where corrosion resistance is an important factor in valve selection.

Applications

Non-return valves can be used across numerous industrial sectors where one-way flow protection is required. Common applications include:

  • Oil and gas processing
  • Refineries and petrochemical plants
  • Chemical processing facilities
  • Water and wastewater treatment plants
  • Power generation plants
  • Pharmaceutical manufacturing
  • Food and process industries
  • Steel and metal processing
  • General manufacturing
  • Industrial utility systems

Valve selection should always consider the actual process conditions, including fluid type, operating pressure, temperature, pipeline size, connection requirements and applicable design or project specifications.
