PQ340H Eccentric Hemispherical Valve

The Y-type inclined valve body structure is matched with the precisely processed valve cone form, which has the characteristics of compact structure and large flow capacity. The measuring unit has the functions of adjustment and shutoff.

The adjustable flow control dynamic balancing valve is used in water systems that require flow control, especially for flow control of non-corrosive liquid media such as heating and air conditioning. A one-time adjustment before operation can automatically keep the system flow constant at the required set value. It can automatically balance the system flow at the required set value; it can automatically eliminate the hydraulic imbalance caused by various factors in the water system, maintain the flow required by the user, overcome "uneven cold and hot", and improve the room temperature qualification rate of heating and air conditioning. It can effectively overcome the unfavorable operating mode of "large flow, small temperature difference", improve the system energy efficiency, and achieve economic operation. The applicable pressure difference range is 20-300KPa. When the working pressure difference of the system fluid exceeds 300KPa, measures should be taken to consume the excess pressure difference to prevent noise. The dynamic balancing valve does not have a shut-off function, and a shut-off valve should be set as needed.
