Profile
 V230/V231 Self Operated Pressure Regulating Valve
 
Brief Introduction.
 
V230/V231 pressure regulating valve is a self-operating pressure regulating valve,there is no need for any external power source, it can use the medium's flow force to realize the function of pressure regulating automatically,is widely used in many industrial sectors like petrochemistry,metallurgy and light indutries,besides,in the civil field,city heating systems can also use this product for regulating pipe pressure.
