Q641-16P Pneumatic Worm Gear Two Piece Hard Sealed Flange Floating Ball Valve

Product Overview

The Q641-16P Pneumatic Worm Gear Two Piece Hard Sealed Flange Floating Ball Valve is a new type of gland-type high platform ball valve developed by Ruiward Valve Company, utilizing a valve body and valve cover assembled with a ball body through silica sol precision casting technology, in accordance with the standards of the Ministry of Machinery. The high platform ball valve can be manually operated or installed with an ISO gland-type direct mounting platform for pneumatic or electric control mechanisms, offering significant advantages such as convenient installation and material savings. The valve seat adopts an elastic sealing structure, ensuring reliable sealing and easy opening and closing. It is equipped with a fire-resistant structure, providing reliable operation and excellent sealing performance. Additionally, it features an anti-static structure to eliminate the effects of static electricity. A 90° switch with a hole positioning piece is set up, which can be locked as needed to prevent misoperation. It is suitable for use on various pipelines with Class150, PN1.0~2.5MPa, and operating temperatures ranging from 29~180℃ (with reinforced polytetrafluoroethylene sealing rings) or 29~300℃ (with p-xylene sealing rings), for cutting off or connecting the medium in pipelines. Depending on the material selection, it can be used for various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, and more.

Performance Characteristics

• The casting has passed the German TUV certification, and it is made through silica sol precision casting, resulting in a delicate and beautiful appearance;
• The valve body features an identical internal cavity and a straight-through flow passage, resulting in low fluid resistance. Its resistance coefficient is equivalent to that of a pipeline of the same length;
• The valve stem features a downward protrusion design, ensuring anti-blowout and anti-leakage for enhanced safety;
• Anti-static structural design ensures that the current between the ball core, valve stem, and valve body is directed outward, preventing electrostatic accidents;
• The valve stem packing adopts a V-shaped design, which becomes tighter with increasing pressure. The packing gland plane undergoes precision machining, achieving zero leakage sealing effect;
• The V-shaped packing, O-ring, and packing follower form a triple seal, exhibiting excellent self-sealing performance;
• Spring disc compensation design, to adapt to the wear of the sealing packing ring, automatically providing elastic compensation effect to reduce leakage;
• Easy to maintain, the ball valve has a simple structure, making it convenient for disassembly and replacement. Equipped with the Japanese Daikin M111 seal as standard, it ensures quality and simplifies replacement and procurement;
• The design of the elastic valve seat ensures elastic contact between the valve seat and the ball, providing strong sealing performance and controllable sealing pressure. It offers elastic clearance for the ball during rotation, ensuring uniform operating torque without jamming, and smoother switching;
• The unique valve body structure is organically combined with the valve seat and the ball. When the valve is fully open or fully closed, the sealing surfaces of the ball and the valve seat are completely isolated from the medium, which prevents erosion of the valve sealing surface and extends the service life;
• The design of the sinking gland allows for micro-adjustment of the compression amount of the packing part, making maintenance more convenient;
• Easy to operate, compliant with the ISO5211 high-platform international standard, it is compatible with various pneumatic and electric valve actuators both domestically and internationally, providing convenience for remote control;
• Ruiward, a valve source manufacturer, possesses excellent CNC machining technology. Its design and machining dimensions are strictly adhered to the industry’s leading standards, as well as 6S, CE, TS, ISO9001, ISO14000, ISO18000, API, and GB standards.
