This valve is of a streamlined control valve with unique design. It can eliminate hydraulic energy, so to slove the cavitation erosion and vibration that happens to gerenal control valve. The valve can adjust or control flow without any restriction. Due to its stable hydraulic operation principle, it will not cause vibration or noise in any possible operation parameter and max. Flow status. It even can be operated in the state of negative pressure at outlet. Therefore, it can be used together with remote monitoring system(PLC). This system enbles to monitor, coordinate and operate supply and transport pipeline system in a remote place on basis of time module. It solves the operation limitation of general rotating type or ball type control valve, and guarantees safe operation of supply and transport pipeline system.
