Description

Self-acting Ring Pressure Regulating Valves , V**0Y***1 ( B, K ) , is a kind of energy-efficient products that only use self pressure without external energy of the adjusted medium to regulate constant pressure or reducing pressure automaticly before or after valves, whose incidental isolate temperature pot can be used hour after hour under three hunder and fifty celsius temperature. They are used widely in Urban heating, warming system, chemical, electronic, metallurgy, food and light industry to reduce pressure , release the valve and keep the pressure.
