Reliable Quarter Turn Operation

The SQK ball valve enables swift and precise flow control with its quarter-turn mechanism. This operational style allows operators to fully open or close the valve in a single, simple movement, ideal for applications requiring rapid shutoff or activation. The stainless steel handle ensures durability and resistance to harsh environments.

Premium Safety Features

Equipped with a blowout-proof stem and fire-safe design, this ball valve is built to protect against potential hazards. The anti-static device further reduces operational risks, safeguarding both personnel and equipment, while a lockable handle (optional) adds another layer of security for controlled access.

Flexible Installation and Application

Designed with a flanged end and ISO 5211 mounting pad, this valve offers easy integration in varied industrial setups. Its compliance with ANSI/DIN/JIS flange standards makes it universally adaptable, catering to processes in water treatment, chemical processing, and oil/gas distribution.

FAQ's of SQK A351 CF8 Stainless Steel Ball Valve:

Q: How should the SQK A351 CF8 Stainless Steel Ball Valve be installed in a pipeline system?

A: The valve should be installed between flanged pipe sections using compatible ANSI, DIN, or JIS end connections. Ensure correct alignment of the flanges and tighten bolts uniformly. The ISO 5211 mounting pad facilitates easy actuator installation if automation is desired.

Q: What are the benefits of a two-piece body design in this ball valve?

A: The two-piece body design simplifies maintenance and inspection, allowing easy access to internal components without removing the valve from the pipeline. It also enhances reliability by providing robust sealing and structural integrity under various pressure conditions.

Q: When is the lockable handle recommended for this ball valve?

A: A lockable handle is recommended when you need to prevent unauthorized operation or accidental opening, especially in critical industrial environments or safety-sensitive installations. It secures the valve's open or closed position for added operational control.

Q: Where can this ball valve be used?

A: The SQK ball valve is suitable for diverse settings such as chemical plants, water treatment facilities, oil refineries, and general industrial processes. Its corrosion-resistant properties and ability to handle water, oil, and gas make it versatile for demanding applications.

Q: What process media can this valve handle and at what temperature range?

A: This valve handles water, oil, and gas with a temperature range from -20C to 180C, making it ideal for systems requiring both low and moderately high-temperature fluid control.

Q: Why is PTFE (Teflon) seat material used in this ball valve?

A: PTFE seats provide excellent chemical resistance, low friction, and high integrity sealing for Class VI leakage prevention. This ensures that the valve performs reliably with minimal wear even in harsh media conditions.

Q: How does the fire-safe design and anti-static device protect the system?

A: The fire-safe design ensures the valve can maintain its sealing even during high-temperature incidents, preventing dangerous leaks. The anti-static device minimizes the risk of electrostatic discharge, especially important in flammable media applications.
