Description
The DN25 Quick Installation Clamp Ball Valve has been precisely polished and sterilized, and uses a fully enclosed F4 seal, which has no dead angles and is easy to clean. Its closing piece is a partial sphere with a hole, which rotates with the valve stem to open or close the valve. It can be used in high-pressure and large-caliber applications to control high-viscosity media with fibers and fine particles.
Fine Smart Electric Actuator
The fine smart electric valve actuator is equipped with a butterfly valve, and its operating life is higher than the standard of similar products. Small and lightweight, easy to disassemble and repair, and can be installed at any location.
Installation
Indoor installation matters at the installation site It is a non-explosion-proof product. Do not install it in a room with explosive gases. Please reserve space for incoming wires and manual operation.
Precautions for outdoor installation Please install a protective cover and make sure the wiring cover is tightly closed after wiring for safety precautions Note: Direct sunlight will cause high temperatures inside the machine and accelerate the aging of components. Rainwater will accelerate the aging of seals, causing water seepage and damaging the machine.
The Use Of Ball Valve
Since ball valves usually use rubber, nylon and PTFE as seat sealing ring materials, their service temperature is limited by the seat sealing ring material. The cut-off function of the ball valve is accomplished by the metal balls pressing against each other between the plastic valve seats under the action of the medium (floating ball valve). Under the action of a certain contact pressure, the valve seat sealing ring will undergo elastic-plastic deformation in local areas. This deformation can compensate for the manufacturing accuracy and surface roughness of the ball and ensure the sealing performance of the ball valve. And since the seat sealing ring of a ball valve is usually made of plastic, when selecting the structure and performance of the ball valve, the fire resistance and fire protection of the ball valve must be considered, especially in petroleum, chemical industry, metallurgy and other departments, in flammable and explosive media When ball valves are used in equipment and piping systems, more attention should be paid to fire resistance and fire prevention.
Usually, in two-position adjustment, strict sealing performance, mud, wear, shrinkage channel, rapid opening and closing action (1/4 turn opening and closing), high-pressure cutoff (large pressure difference), low noise, cavitation and vaporization phenomena, In pipeline systems with small leakage to the atmosphere, small operating torque, and small fluid resistance, ball valves are recommended. Ball valves are also suitable for pipeline systems with light structure, low pressure cutoff (small pressure difference), and corrosive media. Ball valves are also available in cryogenic (cryogenic) equipment and piping systems. In the oxygen pipeline system in the metallurgical industry, ball valves that have undergone strict degreasing treatment must be used. When the main lines in oil pipelines and gas pipelines need to be buried underground, full-bore welded ball valves must be used. When regulating performance is required, a ball valve with a special structure with a V-shaped opening needs to be selected. In petroleum, petrochemical industry, chemical industry, electric power, and urban construction, metal-to-metal sealing ball valves can be used in pipeline systems with operating temperatures above 200 degrees.
