ZZYP, ZZYM type self-reliance pressure differential regulator is an energy saving product without external energy, using pipe pressure change to compare with signal, make the media force and the actuator output force balanced, in order to achieve certain pressure, pressure differential value

These are used to control the flow of water from the boiler to the central heating circuit as well as the hot water system and come in two types

ZDSG type straight travel electric control valve has simple structure, small flow resistance, circulation larger than other valves with diameter, no leakage, can be used for adjusting high viscosity and suspended particles flow, according to the different diaphragm material (rubber or ptfe) applies

The bodies of these control valves are manufactured exclusively from high-quality stainless steel, a material that not only saves on weight, but also considerably enhances the aesthetics of the valves.

Control valves are elements used in process control loops to adjust process variables such as flow, liquid levels, pressure, temperature etc.

One of the most common control element in the process control industry is the control valve. A control valve helps regulate the flow of a fluid (gas, steam, water, or chemical substance) in order to keep the regulated process variables (pressure and flowrate) as close as possible to the desirable se

I suppose that pressure control valve that had the same upstream and downstream conditions regardless of flow
