Product overview

Self-powered pressure balancing control valve is widely used in industry. It is a kind of control device that can automatically adjust by setting a pre-set value without external resources, and only needs to measure the change of pressure, temperature or flow. It is an energy-saving instrument with multi-function of instrument control system such as control and execution. It can be divided into self-operated pressure (micro-pressure) control valve, self-operated (differential pressure) flow control valve and self-operated temperature control valve. Applicable to urban heating, heating and no power supply, gas supply and need to control occasions.
