HL Petroleum Equipment Co., Ltd. recently completed final quality inspection and packaging for a batch of large-diameter 12-inch mud tank bottom valves (also known as bottom flow valves) and officially shipped them to Kazakhstan. These valves will provide reliable fluid control for drilling operations by being used in the mud circulation system of local drilling projects.
Based on years of professional experience, HL Petroleum developed the 12-inch mud tank bottom valves shipped this time as mature products. These valves specifically control drilling mud tank pipelines and compartments using mud as the medium. They handle the on/off control of the bottom suction and discharge pipelines, and also manage compartment balance adjustment. Their core features an innovative valve-type end-face sealing structure and a rotary lifting mechanism. A rotating handwheel drives a lead screw, which smoothly engages and disengages the valve plate and sealing seat, thus completing the valve’s opening and closing action. This design not only makes the sealing performance more stable and significantly extends the service life, but also enables centralized operation on the tank surface, greatly improving the convenience of installation, transportation, and daily use.

The 12-inch large-diameter valve from HL Petroleum meets customer demand. It provides high-flow, high-reliability control for pipelines.
The valve has a compact structure and a rational design. It offers outstanding advantages. These include stable opening and closing and effortless operation.
It embodies the “integrated manifold and tank” design concept. This helps customers optimize mud tank layout. It also improves overall operational efficiency.
HL Petroleum is committed to providing high-quality, high-performance specialized equipment for the oil and gas field drilling industry. This successful shipment demonstrates the company’s professional strength and efficient delivery capabilities in the field of petroleum machinery equipment manufacturing. The company will continue to adhere to a customer-centric approach, providing solid support for domestic and international drilling projects with stable and reliable products.
