Self Pressure Diffential Control Valve

Summary

ENZYC Self Pressure Diffential Control Valve is such a valve as using the self pressure variation to do self control while keep the pressure differential of the medium flowing through this controlled system unchanged. Suitable for the pressure differential control of the warming supply using a dual-pipeline system to guarantee the system basically unchanged, lower the noise, balance the resistance and get rid of the heat-net and hydraulic imbalance.
