Pneumatic thermal insulation jacketed ball valve introduction
Pneumatic thermal insulation jacketed ball valve is the piston is composed of pneumatic actuators and jacket insulation ball valve, with good heat preservation and cooling characteristics, and the diameter of Pneumatic thermal insulation jacketed ball valve is consistent with the pipe diameter, and can effectively reduce the heat loss of the medium in the pipeline.Valve positioner can be equipped with input control signal (4-20MADC or 1-5VDC) air source to control the operation.Pneumatic thermal insulation jacketed ball valvecan also be equipped with travel limit switch, solenoid valve, triplet and 0.4-0.7mpa air source to realize switching operation, and send two pairs of passive contact signals indicating the switch of the valve.Pneumatic thermal insulation jacketed ball valve is mainly used in petroleum, chemical industry, metallurgy, pharmaceutical, food and other systems to transport the high viscosity medium will solidify at room temperature.As a result of Pneumatic thermal insulation jacketed ball valve adopts the integral structure, so pneumatic jacket insulation ball valve is smaller than the general ball valve, light weight, and no leakage, good sealing performance, jacket welding carbon steel tube than casting more durable pressure.
