Q341H-16P full bore DBB forged steel three piece double block double discharge high-pressure double ball valve

Product Overview

The Q341H-16P full bore DBB forged steel three piece double block double discharge high-pressure double ball valve which stands for Double Block and Bleed ball valve, possesses dual isolation and bleed functions. This valve achieves double isolation of the medium through two independent sealing surfaces, ensuring complete isolation between upstream and downstream pipelines and preventing medium flow. When the valve is closed, the two sealing surfaces isolate the upstream and downstream media respectively, ensuring operational safety. Furthermore, a bleed port is designed between the two sealing surfaces of the Q341H-16P full bore DBB forged steel three piece double block double discharge high-pressure double ball valve, facilitating the discharge of accumulated medium or pressure release, and aiding in the testing of sealing performance. This design not only enhances system safety but also simplifies the pipeline system, reducing installation and maintenance costs.

Performance Characteristics

• The casting has passed the German TUV certification, and it is made through precision silica sol casting, resulting in a fine 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, providing excellent self-sealing performance;
• Spring disc compensation design, to adapt to 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 to disassemble and replace. Equipped with the Japanese Daikin M111 seal as standard, it ensures quality and simplifies replacement and procurement;
• With an elastic valve seat design, the valve seat makes elastic contact with the ball, ensuring strong sealing performance and controllable sealing pressure. This design provides 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, it adheres to the ISO5211 high-platform international standard, and is compatible with various pneumatic and electric valve actuators both domestically and internationally, facilitating remote control;
• As a source manufacturer of valves, Ruiward’s boasts excellent CNC machining technology. Its design and machining dimensions are strictly adhered to industry-leading standards, as well as 6S, CE, TS, ISO9001, ISO14000, ISO18000, API, and GB standards.
