Pneumatic screw ball valve
The Pneumatic Screw Ball Valve is an automated flow control valve that combines a high-performance ball valve with a pneumatic actuator, providing fast operation, reliable shut-off, and efficient remote control capabilities. Designed with a screw threaded connection structure, it offers convenient installation, compact design, and excellent sealing performance for various industrial piping systems.
Pneumatic screw ball valve
The valve adopts a precision-machined ball and sealing structure to ensure low torque operation, smooth flow control, and long service life. With pneumatic actuation, it enables quick opening and closing, making it suitable for automated processes requiring frequent operation and accurate fluid control.
We provide professional OEM manufacturing and customization services, including customized valve sizes, body materials, thread standards, pressure ratings, actuator types, control accessories, sealing materials, surface treatments, logo marking, and packaging solutions. Our products are manufactured under strict quality management systems with complete valve industry certifications, inspection procedures, and testing capabilities to ensure compliance with international standards and customer requirements.
