This can reduce the friction between internal materials and structural parts, reduce the loss of equipment, and better ensure the stable and long-term operation of equipment.

Other applications include industrial water treatment, drinking water treatment, chemical pools in swimming pools, water parks and wastewater systems, chemical distribution, electroplating and power plants. The unique double eccentric design of the 567 valve has an off center shaft, which makes the disc completely separate from the disc seal, even if it is partially open. Longer service life and minimal maintenance reduce seal friction, which is the result of a non eccentric valve style. The dual eccentric design only needs about half of the torque of the traditional guide design, thus reducing the seal wear on the disc and further improving the service life of the product. Other advantages of this design include easy manual operation, lower device compatibility to reduce installation costs, better protection, and resistance to pressure fluctuations. The new large size valves feature industry standard ISO flanges for easy installation with most electric or pneumatic actuator drives. Other features include bi-directional capability at 70 ° F, pressure class 90 diffusion resistance and handwheel. The valve can be both EPDM or procedure manual sealed, 304 or 316 stainless steel dry, and polypropylene body
