Focusing on ergonomics, the design of Nanfang cryogenic ball valves has incorporated many elements. They are the distribution of load, weight & balance, arch support, foot proportion, etc. 2.
Strict quality control system to ensure product quality to meet international standards. 3.
Perform regular performance checks are applied to ensure high performance and reliable quality. 4.
The product is of easy maintenance. It does not need to replace for its electric wires even after years of use. 5.
The product would be a great way for people who want to cut down their expenditures. It helps save people's money on a monthly basis because it uses far less electricity.
Two pieces design in small size, and three pieces design in large size. Floating ball construction in DN15 through DN150, and Trunnion mounted ball construction in DN200 through DN500. The ball is using special surface treatment technology to ensure good abrasion resistance. Valves with PTFE seats can reduce the wear, and improve sealing performance and extend the service life. Valves can be equipped with gear, pneumatic and electric actuators.
l The seats compensate automatically for wear and fluctuations of pressure and temperature.
l Blowout-proof stem. The stem is made separately from the ball. The lower end of the stem is designed with an integral collar to be blowout-proof, assuring sealing at all pressure.
l Long cycle life.
l Low, uniform torques.
l Anti-static device. A spring-loaded pin assures the electrical continuity between the ball, stem, and body, to avoid sparking during the turning of the stem to open and close the valve.
l Meets ASME B16.5, B16.10 and B16.34, API 608, API 598, API 607/ ISO 10497.
