Exceptional Durability with Tungsten Carbide Coating

The SQK Ball Valve incorporates a tungsten carbide coated steel ball, providing superior surface hardness (up to 90 HRC) and mirror polished finish. This ensures outstanding wear resistance, minimized friction, and long-term reliability even in aggressive media. The robust coating protects against corrosive and abrasive substances, extending the service life in harsh industrial environments.

Versatile Actuation and End Connection Options

This ball valve supports multiple actuation methods including manual lever, gear operator, electric actuator, and pneumatic actuator. It offers flexible end connections such as wafer, lug, socket weld, and butt weld types, as well as compatibility with international flange standards (ANSI, DIN, JIS). This versatility enables the valve to integrate easily into diverse piping systems, maximizing operational flexibility.

Designed for Safe and Reliable Operation

Engineered for business-critical systems, the valve features a fire-safe design, blow-out proof stem, anti-static device, and a mounting pad compliant with ISO 5211. Rigorous leak testing in accordance with API 598 and compliance with API, ASME, and ISO design standards guarantees reliable and safe performance, even under high-pressure or hazardous service conditions.

FAQs of SQK Tungsten Carbide Coating Ball Valve:

Q: How does the tungsten carbide coating improve the performance of the SQK ball valve?

A: The tungsten carbide coating dramatically increases the hardness of the ball surface (up to 90 HRC), providing exceptional resistance to abrasion and corrosion. This prolongs the lifespan of the valve, reduces maintenance needs, and ensures reliable operation in harsh industrial applications.

Q: What types of media can the SQK Tungsten Carbide Ball Valve handle?

A: This valve is designed to control a variety of media including water, gas, oil, and corrosive liquids. Its robust construction and superior corrosion resistance make it ideal for use in industrial chemical, oil & gas, and power plant applications.

Q: When should I select metal seated versus PTFE seated options?

A: PTFE seated ball valves are recommended for applications requiring chemical resistance and lower temperatures, while metal seated variants are suited for high-temperature or abrasive environments. Selection should be based on your process media, operational temperature, and severity of service conditions.

Q: Where can the SQK ball valve be installed and what are its end connection options?

A: The valve can be installed in any industrial pipeline that matches its end connection options, which include wafer, lug, socket weld, butt weld, and flanged connections meeting ANSI, DIN, or JIS standards. This flexibility allows use in a wide array of installation scenarios.

Q: What is the typical process for installing and actuating this ball valve?

A: The valve features a mounting pad (ISO 5211) for easy actuator assembly and can be operated manually, or upgraded to gear operated, electric, or pneumatic actuators depending on process automation needs. Installation involves matching the valves end connection to the pipeline before fastening and actuating as required.

Q: Why is the API 598 testing standard important for this product?

A: API 598 is an industry-standard leakage test ensuring that the valve provides reliable, leak-tight service. Conformance to this standard guarantees that each SQK Tungsten Carbide Ball Valve performs efficiently and safely before delivery.

Q: What are the main benefits of using this valve in high-pressure or corrosive environments?

A: Its excellent corrosion protection, high ball surface hardness, fire safe and anti-static features, and compliance with international standards, provide operational safety, durability, and trustworthiness in critical and challenging environments.
