Flow valve works
Flow valve is a manual control valve group and a self-balancing valve group. Regulating valve group is to set the role of flow, valve automatically balance the role of maintaining a constant flow. System fluid working pressure P1, manual control valve before and after the pressure was P2, P3. When the manual control valve transferred to a certain position, that is, to determine the "set flow" Kv manual valve flow coefficient, flow G = Kv (P2-P3), Kv, Kv set, as long as the P2- P3 unchanged, the flow G unchanged. When the system flow rate increases, the actual value of (P2-P3) exceeds the allowable given value. At this moment, the automatic regulating valve group will be automatically closed by the action of the pressure sensitive membrane and the spring until the flow rate is maintained again to the set flow rate, vice versa. Flow valve automatically adjusts the effective range of flow depends on the performance of the working spring. General flow valve before and after the pressure difference in the range of 20-300kPa can set the value of effective control of flow. When the pressure is less than 20kPa, the control flow does not reach the set value; pressure exceeds 300kPa, it may produce noise. More Keyword Search: Flow Valve
