What is the Role of the Radiator Balancing Valve?

The radiator thermostatic balancing valve is a self-operated constant temperature flow control valve mounted on the radiator. It is composed of a thermostatic valve body and a temperature regulating device for air temperature sensing. The principle of action is that the opening of the thermostatic valve body is automatically controlled to change the amount of hot water passing through the radiator. When the room temperature is lower than the set temperature value, the…See More

Dynamic Flow Balancing Valve

Function: The dynamic flow balance valve keeps the flow constant between 31-600KPa.Role: Keep the flow through the valve constant.Theory: When the incoming flow pressure P1 increases, the sleeve of the valve sleeve moves downward, compressing the spring inside the valve bladder, and reducing the flow area of the valve hole at the bottom of the valve bladder, that is, reducing the Kv value of the valve bladder. Thus, although the pressure difference ΔP across the damper is increased, the Kv…See More

Triple Offset Butterfly Valve

To withstand high temperature, the metal seal must be used, but large leakage; For zero leakage, rubber seal must be used, but not high-temperature resistant. In order to overcome the contradiction of the double eccentric butterfly valve china, the triple offset butterfly valve was carried out.The structural characteristics of the double eccentric eccentric axis of the stem position at the same time, make the…See More

The Difference between Thermostatic Balancing Valve and Auto Balancing Valve

Posted on November 16, 2019 at 8:30pm 0 Comments

The difference between the two balancing valves is that the thermostatic balancing valve

manually adjusts the opening degree of the thermostat valve, while the auto balancing valve automatically adjusts the opening degree of the thermostat valve by using temperature sensors.

Thermostatic balancing valve (referred to as constant temperature valve) is an…

Balancing valve types

 

  1. Static Balance Valve: It is also called Balance Valve, Manual Balance Valve, Digital Lock Balance Valve, Double Position Regulating Valve, etc. It changes the flow resistance through the valve by changing the clearance (opening) between the spool and the seat to achieve the purpose of regulating the flow rate. Its object of action is the…
