It's mainly used for oil and natural gas storage and transportation, the chemical industry, metallurgy, paper making, food, shipbuilding and other industries to do the opening and closing control of media devices, coupled with pneumatic or electrical device can also be achieved remotely, bail operator safety.
(1).Locking, and limit device to prevent misuse of the valve, the valve can be equipped with a lock limit institutions, especially in the field or for the installation process does not allow to open or close the valve, causing security to prevent misuse of others accident, the valve lock is necessary;
(2).Fire safe, the a fire occurs, when the non-metallic materials of the valve seat and seal damaged at high temperatures, a specially designed metal to metal secondary seal structure, effectively prevent the media a lot of leakage;
(3).Anti-blow out stem design, stem the use of downloading structure, preventing the abnormal increase as intraluminal pressure forced Blow Out the accident; PTFE thrust washers to ensure smooth between the stem and valve operation;
(4).Anti-static design, to ensure that working conditions in the explosive on the safe use;
(5).Body cavity pressure relief design to ensure reliable sealing valve, and extending its life;

Step 1: Order and Design
Production starts after confirming the customer’s requirements, including valve size, pressure rating, material, connection type, and operating conditions. Based on the application, the engineering team prepares the drawings and production plan to ensure the floating ball valve meets performance and sealing requirements.
Step 2: Forging & Casting
The main components such as the valve body, bonnet, and ball are produced from qualified raw materials through forging or casting, depending on the design and specification. This process ensures the valve parts have sufficient strength, pressure resistance, and structural reliability.
Step 3: Machining
All key components are precisely machined using CNC equipment to achieve accurate dimensions and smooth sealing surfaces. Special attention is given to the ball, seat pocket, stem hole, and threaded or flanged connections to ensure proper fit and stable operation.
Step 4: Assembly
After machining and cleaning, all parts are assembled by experienced technicians. The ball, stem, seats, seals, gasket, and other internal components are installed carefully to ensure reliable sealing performance, smooth opening and closing, and long service life.
Step 5: Testing & Quality Assurance
Each floating ball valve undergoes strict inspection and testing before delivery, including dimension inspection, shell test, seat leakage test, and operational test. This step ensures the valve meets relevant standards and performs safely under working pressure.
Step 6: Painting and Finishing
After testing, the valve surface is cleaned and treated with anti-rust protection or coating as required. Final finishing includes marking, nameplate installation, packaging, and preparation for shipment to ensure the product arrives in good condition.
