The swing-type disc allows for unidirectional flow, automatically closing to prevent backflow, protecting pumps, compressors, and other sensitive equipment. Available in pressure classes of 900#, 1500#, and 2500#, it is built to handle extreme pressures and temperatures, making it ideal for industries such as oil & gas, petrochemical, power generation, and refinery operations. The valve comes with both flanged ends and butt weld ends to accommodate a variety of pipeline connection requirements.

- Pressure Seal Bonnet: Designed for high-pressure services, the pressure seal bonnet offers a tight, leak-proof seal that improves as system pressure increases, making it particularly suitable for high-pressure and high-temperature environments.
- Swing Check Mechanism: The swing-type disc automatically closes upon reverse flow, ensuring reliable protection of downstream equipment without manual intervention.
- High-Pressure Ratings: Available in Class 900#, 1500#, and 2500#, this valve is engineered to perform under extreme pressure conditions, ensuring durability and safety.
- End Connections:
- Flanged Ends: Conforming to ASME B16.5, these allow for easy installation and removal in pipeline systems, providing secure, leak-tight connections.
- Butt Weld Ends: Conforming to ASME B16.25, these provide high-strength welded connections suitable for extreme conditions, minimizing the risk of leakage.
- Rugged Construction: Fabricated from premium materials such as carbon steel, stainless steel, and alloy steel to ensure long-term performance and corrosion resistance in aggressive environments.
- Minimal Pressure Drop: The design of the valve allows for smooth flow with minimal pressure loss, enhancing system efficiency.
- Self-Operating: Requires no manual operation or external energy to function, reducing the complexity of the system.
Testing & Certification:
- Hydrostatic and pneumatic testing according to API 598.
- ISO 9001 certified manufacturing processes.
- NACE MR0175 compliance for sour service environments available upon request.
