DQ641F-40P/C Pneumatic two-piece ultra-low temperature forged steel ball valve

Unique Advantages

• The casting has passed the German TUV certification and is precision cast with silica sol, with a delicate and beautiful appearance.
• Completely equivalent valve body cavity, direct flow channel, low fluid resistance, and its resistance coefficient is equal to that of pipes of the same length.
• The protruding design of the valve stem prevents blowing and leakage, making it safer.
• Anti static structure design ensures that the current between the ball core, valve stem, and valve body is guided outward to avoid static accidents.
• The V-shaped design of the valve stem packing tightens with increasing pressure, and the packing pressure ring plane is precision machined to achieve zero leakage sealing.
• The V-shaped packing, O-ring, and packing pressure ring form a triple seal, which has good self sealing effect.
• The spring disc compensation design is designed to adapt to the wear of the sealing packing ring, and the automatic elastic compensation effect reduces leakage.
• Easy maintenance, simple ball valve structure, easy disassembly and replacement, standard Japanese Daikin M111 seal, guaranteed quality, and easier replacement and procurement.
• Elastic valve seat design, with elastic contact between the valve seat and the sphere, strong sealing performance, controllable sealing pressure ratio, providing elastic avoidance for the sphere to rotate, uniform operating torque without jamming, and smoother switching.
• The unique valve body structure is organically combined with the valve seat and sphere. When the valve is fully open or fully closed, the sealing surfaces of the sphere and valve seat are completely isolated from the medium, which will not cause erosion of the valve sealing surface and has a longer service life.
• The sunken cover design allows for adjustable compression of the packing portion, making maintenance more convenient.
• Easy to operate, ISO5211 high platform international standard, compatible with various types of valve pneumatic actuators and valve electric actuators at home and abroad, providing convenience for remote control.
• Ruiward is a source manufacturer with excellent CNC machining technology. The design and machining dimensions strictly follow industry standards and 6S, CE, TS, ISO9001, ISO14000, ISO18000, API, GB standards.
