1. Self operated pressure regulating valve: a self operated pressure (differential pressure) regulating valve that does not require external energy and is driven by the pressure difference of the medium itself to stabilize the pressure of the controlled object (such as pipeline outlet pressure and equipment internal pressure). It is commonly used for stabilizing pressure in steam, gas, and liquid systems.
2. Self operated temperature regulating valve: With the help of medium temperature changes (such as temperature sensing temperature expansion/contraction), the valve core is driven to move, and the medium flow rate is controlled to stabilize the temperature. It is suitable for temperature control scenarios such as hot water and hot oil.
3. Self operated flow control valve: relying on the flow rate changes of the medium itself, the flow area is automatically adjusted through the valve mechanism to maintain stable flow without manual or external signal intervention. It is commonly used in pipeline systems that require constant flow.
