Steel plate valves compatible with all flange standards. The face-to-face dimension can also be customized to specifications. They demonstrate their performance in lines requiring large diameters, such as exhaust gas from steel mills, ventilation and air conditioning in power plants, and solvent recovery in chemical plants. <Details of Seat Structure> - The seat is an endlessly molded packing made from a special mold. - When the seat retaining bolts are tightened, the seat is pushed outward; when loosened, it retracts inward. - The contact width can be finely adjusted by the seat retaining bolts. - This special structure allows for the adjustment of the contact width of the seat suitable for fluid pressure, maintaining complete airtightness while avoiding excessive friction, prolonging the lifespan of the seat, and achieving optimal torque. *When replacing the seat, it can be easily done without removing the valve from the piping.

After absorbing moisture from compressed air using the adsorbent (activated alumina) in the adsorption tower to produce dry air, moisture is removed from the adsorbent by reducing the pressure in the tower, allowing for regeneration. This "air drying" and "adsorbent regeneration" are alternately repeated using two adsorption towers, achieving continuous and large-scale production of dry air. Additionally, the regeneration of the adsorbent utilizes a portion of the dry air, eliminating the need for a heat source, making it an innovative system that excels in energy efficiency and maintenance.
