D01 Pressure reducing regulators provide a desired and constant downstream pressure,even though the upstream pressure changes.The pressure which the regulators maintain we call it setting point pressure.For the pressure reducing regulators the valve closes when the downstream pressure rises and opens when the downstream drops.
D02 Pressure relief regulators or we can call it excess pressure regulators provide a desired and constant upstream pressure.The upstream pressure which the regulators matain we call it setting pressure.For the pressure relief regulators the valve opens when the upstream pressure rises.Pressure relief regulators are necessary for the pipeline system to get free of overpressure damages.
D03 Differential pressure regulators are widely used for industrial applications. Such as city heating systems, large building heating networks and etc.The pressure differential regulators can matain a constant differential pressure between inlet and outlet pressure point.
The valve closes when the differential pressure rises.The typical application is the direct connection of district heating systems(Installation of flow pipe).
D04 Differential pressure regulators are widely used for industrial applications.Such as city heating systems, large building heating networks and etc.The pressure differential regulators can matain a constant differential pressure between inlet and outlet pressure point.
The valve opens when the differential pressure rises.The typical application is the indirect connection of district heating systems(Installation of return flow pipe).
D12 Pilot operated regulators are typically used for these applications which need large flowrate or precise pressure control is required. Pilot operated pressure reducing regulators are consisted of main valve and pilot valve,when the pilot valve detected the downstream pressure rises,it will respond quickly and accurately to close,after the pilot valve closing,the main valve will also been closed by the upstream pressure.Through above two pathes,the regulator achieve the purpose of pressure reducing.

The self-operated temperature regulator (divided into heating type and cooling type) is a kind of energy-saving product which does not need external energy and only relies on the temperature change of the controlled medium itself to automatically adjust.
This product is mainly used in the automatic temperature control system of various heat exchangers with non-corrosive steam, hot water and oil as the medium. It can be widely used in the automatic temperature control system of city heating and heating system as well as petrochemical, printing, pharmaceutical, boiler and other industries.
The temperature regulators for heating installations consist of a globe valve and control thermostat with set point adjuster, a capillary tube and temperature sensor operating according to the adsorption principle. The valves close when the temperature rises.

The temperature regulators for heating installations consist of a globe valve and control thermostat with set point adjuster, a capillary tube and temperature sensor operating according to the adsorption principle. The valves opens when the temperature rises. This regulator is therefore suitable for plants to be cooled.
