Product Description

Self-operated differential pressure control valve is an automatic constant pressure differential valve for balancing hydraulic conditions. It is used in water systems such as centralized arch heating and central air conditioning. Especially suitable for household metering heating system and variable flow air conditioning system. Ensure that the system is basically unchanged, reduce noise, balance resistance, eliminate heat network and hydraulic imbalance.

Product Features

1. It is suitable for the water system that needs flow control, especially suitable for the flow control of non-corrosive liquid media such as heating and air conditioning.

2. Installed in the water system, after one adjustment before operation, the system flow can be automatically constant at the required set value.

3. It can automatically eliminate the hydraulic imbalance caused by various factors in the water system, maintain the flow required by the user, and overcome the "uneven heating and cooling".

4. Improve the qualified rate of room temperature for heating and air conditioning.

5. It can effectively overcome the bad operation mode of "large flow and small temperature difference", improve the energy efficiency of the system, and realize economical operation.
