Pressure balance lubricated plug valves are metal seated valves providing a tight shut off ( 0 leakage ) sealing, valves shall be regularly lubricated along with their operation by injection of suitable grease. Due to no body cavity and as well as a simple & tough design, they are highly recommended for any critical Full P operation and for handling any media with an high % of solids contents, further more they provide an excellent resistance to abrasion, they are free from routine maintenance, providing a long service life.

Exceptional Corrosion Resistance

Built from A182 F51 duplex stainless steel, this plug valve is engineered to resist aggressive environments, including those encountered in oil, gas, and chemical processing industries. Its robustness extends operational life and reduces maintenance costs by protecting against pitting and stress corrosion.

Versatile Pressure and Temperature Handling

Designed with versatility in mind, the SQKL valve manages pressure ratings from Class 150 to 600 and PN16 to PN100, and operates efficiently across a temperature range of -29C to 180C. This makes it suitable not just for standard, but also for challenging and variable process conditions.

Comprehensive Quality Assurance

Each valve undergoes rigorous hydrostatic and pneumatic testing to international standards. With precision engineering and strict adherence to ASTM, ASME, and API requirements, users benefit from safety, leak-tight operation, and peace of mind in critical service applications.

FAQ's of SQKL A182 F51 Duplex Stainless Steel Plug Valve:

Q: How is the SQKL A182 F51 Duplex Stainless Steel Plug Valve operated?

A: This plug valve is manually operated using a quarter-turn (90) mechanism, allowing quick and easy opening or closing. Its design ensures straightforward operation, minimizing effort required during process changes.

Q: What are the main applications for this plug valve?

A: The SQKL A182 F51 valve is widely used in petrochemical, oil & gas, chemical industries, and water treatment plants. It performs reliably in systems transporting water, oil, gas, and highly corrosive liquids.

Q: When should I choose a duplex stainless steel plug valve over other materials?

A: Duplex stainless steel is ideal when high corrosion resistance and mechanical strength are required, especially in aggressive or offshore environments. It is best selected for processes where pitting, stress corrosion cracking, or erosion are common concerns.

Q: Where can this valve be installed within a piping system?

A: This valve can be installed wherever flow control or shutoff is required along a pipeline or process system. Supported end connections include flanged, screwed, socket weld, and, upon request, butt weld, fitting a wide range of installation requirements.

Q: What testing processes ensure the valve's reliability?

A: Each valve undergoes 100% hydrostatic and pneumatic testing as per ASTM, ASME, and API standards. This process guarantees leak-tightness (Class VI) and operational safety before delivery to customers.

Q: What are the benefits of a non-lubricated, tapered plug design?

A: The non-lubricated, tapered plug design reduces maintenance requirements and avoids the risk of lubricant contamination. It also provides smooth operation and consistent sealing performance, even after extended use.

Q: Can I use this valve with both PTFE and metal-to-metal sealing?

A: Yes, the SQKL A182 F51 Plug Valve is available with either PTFE or metal-to-metal sealing, allowing users to select the best option for their specific media and operating conditions.
