2PC Carbon Steel Ball Valve 2000WOG with Locking Device

Shangtai 2PC Carbon Steel Ball Valve 2000WOG with Locking Device is designed for reliable on/off control in high-pressure industrial pipelines. With a pressure capability of up to 1975 PSI, this valve is suitable for demanding water, oil, gas, compressed air, and compatible industrial fluid applications under non-shock conditions.

The two-piece body structure makes the valve more serviceable than many one-piece designs. When maintenance is required, the valve can be disassembled more conveniently, allowing replacement of seats and sealing components to extend service life and reduce replacement cost.

To ensure consistent quality, the valve is inspected through four quality control stages from raw body blank to finished product:

Raw body blank inspection – checks appearance, dimensions, and material condition.

Machining inspection – verifies threads, sealing surfaces, bore accuracy, and key dimensions.

Assembly inspection – checks ball, seats, stem, sealing rings, handle, and locking device.

Final inspection – includes pressure testing, leakage testing, operation testing, marking, and packaging inspection.

This strict quality process helps improve product consistency, reduce defective rates, and deliver more reliable valves for industrial customers.

Valve Working Principle

A ball valve controls flow by rotating a precision-drilled ball inside the valve body.

Open Position

When the handle is parallel to the pipeline, the hole through the ball is aligned with the pipe. Fluid passes through the valve with low flow resistance.

Closed Position

When the handle is turned 90 degrees, the solid side of the ball blocks the flow path. The seats press against the ball to create a tight shut-off seal.

Locking Function

After the valve is opened or closed, the locking device can secure the handle position. This helps prevent misoperation, unauthorized operation, or accidental movement caused by vibration.

Two-Piece Maintenance Design

The two-piece body allows easier disassembly compared with a one-piece valve. Seats, seals, and related sealing parts can be inspected or replaced when needed, helping extend the valve's working life.

Note: Ball valves are mainly designed for fully open or fully closed service. Long-term throttling is not recommended because it may damage the ball and seats.

Applicable Industries and Reasons

Selection note: Carbon steel is strong and cost-effective, but it is not the best choice for highly corrosive media. For corrosive chemicals or marine environments, stainless steel or special material options should be considered.
