Dual Plate Check Valve Manufacturer in India

Forex Valves is a trusted Dual Plate Check Valve Manufacturer in India, offering engineered check valve solutions designed for reliable backflow prevention in industrial piping systems. Our dual plate check valves are developed according to API 594 design requirements and tested as per API 598 standards to deliver dependable shut-off performance, low pressure loss, and long operational life.

Dual Plate Check Valves are widely used in industries where preventing reverse flow is critical for protecting pumps, compressors, pipelines, and process equipment. With compact construction, fast closing action, and multiple installation configurations, these valves provide an efficient alternative to conventional swing check valves.

What is a Dual Plate Check Valve?

A Dual Plate Check Valve is a non-return valve that uses two semi-circular plates mounted on a central shaft to control fluid flow in one direction. When the pipeline flow moves forward, the plates open automatically. When the flow reduces or reverses, spring-assisted plates close quickly to prevent backflow.

The dual plate design provides faster response compared to traditional check valve designs, helping reduce pressure surges and water hammer effects in pipeline systems.

Dual Plate Check Valve Design Features

Forex Valves manufactures dual plate check valves with design features suitable for demanding industrial applications.

  • API 594 compliant design for wafer and check valve applications
  • API 598 testing for pressure and leakage verification
  • API 6D design suitability for pipeline applications
  • Retainer-less design to reduce potential leakage points
  • Fugitive-emission-free design for improved sealing performance
  • Zero-velocity non-slamming operation to minimize impact during closing
  • Spring design tested for more than 1 million cycles

Dual Plate Check Valve Configurations

Dual Plate Check Valves are available in different end connection configurations to match pipeline requirements.

  • Wafer Type Dual Plate Check Valve – Compact design installed between pipeline flanges
  • Flanged Dual Plate Check Valve – Used where bolted flange connections are preferred
  • Lugged Dual Plate Check Valve – Suitable for applications requiring easy installation and maintenance
  • Butt-Welded Dual Plate Check Valve – Used in high-integrity pipeline systems
  • Hub-Ended Dual Plate Check Valve – Designed for specific process and pipeline applications

The selection of configuration depends on piping design, pressure requirements, installation conditions, and application standards.

Seat Options for Dual Plate Check Valves

Soft Seated Dual Plate Check Valve

Soft seated designs are used where tight shut-off performance is required under suitable operating conditions. These valves are commonly selected for applications requiring reliable sealing and reduced leakage.

Metal-to-Metal Seated Dual Plate Check Valve

Metal-to-metal seated designs are preferred for higher temperature and demanding industrial environments where durability and resistance to operating conditions are important.

The appropriate seat design depends on fluid characteristics, temperature range, pressure conditions, and service requirements.

Pressure, Size and Temperature Range

Dual Plate Check Valves are available for a wide range of industrial operating conditions.

  • Size Range: 2" to 120"
  • Pressure Ratings: ANSI Class 125–2500
  • API Pressure Classes: API 5000–10000
  • Temperature Range: −196°C to 900°C
