Our 2PC Ball Valve with Locking Device adopts precision thread design for easy installation and maintenance, making it suitable for working conditions with frequent opening and closing and all types of industrial fluid systems. Thanks to the two-piece split structure, internal sealing rings and other spare parts can be replaced individually without swapping the entire valve body, extending service life and cutting your operating costs.
Fitted with an integrated open-close locking device, this valve effectively prevents accidental actuation and subsequent equipment losses under frequent cycling, making it an ideal component for pipeline control. We supply multiple material options including 304 stainless steel, 316 stainless steel and carbon steel, with sizes ranging from 1/4 inch to 6 inches to match your pipeline specifications.
This 2-piece lockable ball valve holds international certifications including ISO9001 and CE to fully meet your stringent quality standards.
Safety is our core design principle, reflected in the anti-blowout stem structure. If you seek premium quality paired with cost competitiveness, this valve is our sincere recommendation.

FAQ
What is the maximum pressure rating of this ball valve?
The maximum pressure rating is 6.3 MPa.
What is the maximum temperature resistance of this ball valve?
The maximum temperature resistance is 280°C, depending on the valve materials and operating conditions.
What type of packaging is used for the valves?
Each valve is packed in a thick corrugated inner carton, with a plywood case used as the outer packaging for protection during transportation.
Can a 2PC Ball Valve with Locking Device be installed vertically?
Yes. Ball valves can generally be installed horizontally or vertically, including with the stem pointing upward or downward, provided the installation is suitable for the valve and the operating conditions. The actuator or handle should also remain accessible for operation.
What is an anti-blowout stem in a ball valve?
An anti-blowout stem is designed to prevent the valve stem from being ejected from the valve body by internal pressure. This design provides additional safety for high-pressure fluid control applications.
