Engineered for Heavy-Duty Applications

The SQK Gate Valve Class 4500 is built to endure rigorous industrial environments. Designed with forged steel, a bolted bonnet, and metal seating, it meets API and ASME standards for safety and reliability. Its broad operating temperature and pressure ranges make it ideal for critical applications involving oil, water, gas, and steam. With a wide selection of port sizes and compatibility with both horizontal and vertical installations, it keenly adapts to diverse system requirements.

High Performance and Reliable Sealing

This gate valve utilizes a non-rising stem, ensuring smooth operation in space-constrained setups. Graphite packing and a metal-to-metal seat deliver consistent, leak-proof sealing even under extreme pressures or temperature fluctuations. The bidirectional design guarantees flexibility in system flow orientation. Its polished surface and robust material selection further equip the valve for demanding industrial processes, while the manual handwheel operation ensures control and precision.

FAQs of SQK Gate Valve Class 4500:

Q: How is the SQK Gate Valve Class 4500 installed in a piping system?

A: The SQK Gate Valve can be mounted either horizontally or vertically, and its flanged ends (as per ASME B16.5/B16.11) allow straightforward connection to various pipeline systems. Proper alignment and torque tightening according to standard installation practices are recommended for optimal performance.

Q: What types of media are suitable for use with this gate valve?

A: The valve is compatible with a range of media, including oil, water, gas, and steam. Its design allows operation in high-pressure and high-temperature scenarios, making it suitable for petrochemical, power, and process industries.

Q: When should the metal-seated, bolted bonnet structure be chosen?

A: The metal-seated, bolted bonnet structure is ideal for applications that demand high sealing integrity, resistance to thermal cycling, and resilience under elevated pressure or temperaturea common requirement in Class 4500 industrial contexts.

Q: Where is this valve typically utilized?

A: This valve is widely used in India across petrochemical plants, power generation facilities, refineries, and diverse process industries, wherever reliable shutoff and control of pressurized media are necessary.

Q: What benefits does the non-rising stem design offer?

A: A non-rising stem conserves vertical space, making the valve suitable for compact or restricted installations. It also reduces exposure and limits stem wear, enhancing operational longevity.

Q: How do I ensure long-term reliability and sealing performance?

A: Routine inspection of the graphite packing and the metal seat is recommended. Prompt attention to packing adjustment and periodic lubrication of the handwheel/stem mechanism will maximize sealing performance and valve lifespan.

Q: What port size range is covered by this product?

A: The SQK Gate Valve Class 4500 accommodates port sizes ranging from DN25 to DN1200 (2 inches to 48 inches), supporting a wide array of system requirements.
