Cut-off valve adopts pneumatic tee guide structure, with many spring actuators. With compact structure, light weight, action quick, fluid channels in an s-shaped streamline, small pressure drop loss, large capacity of valve, convenient tear open outfit.
Cut-off valve receives signals from the monitoring instrument, cut off the flow direction of medium, open or change, reach the pressure, flow, process parameters, such as temperature or liquid level automatic control. Widely used in petroleum, chemical, metallurgical, power, light industry, textile and other industrial sectors of production process automatic control and remote control system.
The series of products have a diaphragm and piston type two kinds. Body structure with single seat, sleeve, two-seater, three kinds of sealing form has two kinds of packing seal and bellows seal, the nominal pressure range PN10-PN64, nominal diameter range DN25-DN800, temperature range 60℃-450℃.
