针型阀，20DV系列分配阀 Needle Valve, Diverter 20DV Series - 20,000 PSI

派克Autoclave的20DV系列分流阀经专门设计，可在高达20,000 psi（1379 bar）的压力下安全可靠地运行。这种紧凑型阀用于将流量从一个入口转移到两个出口，从而允许改变流向和/或混合过程。Parker Autoclave's 20DV Series diverter valves are built to operate safely and reliably up to 20,000 psi (1379 bar). This compact valve is used to divert flow from one inlet to two outlets permitting flow direction change and/or mixing of processes.

Parker Autoclave的20DV系列分流针型阀设计有不旋转的上升杆阀，工作压力达20,000 psi（1379 bar）。该分流阀使用的Parker高压釜管的尺寸从9/16“”到1“”。分流阀可将进入的流量引导至两个出口之一。通过向内或向外旋转手柄来改变流量，从而导致双头杆堵塞了不需要的出口流路。Parker Autoclave's 20DV Series diverter needle valves are designed with a non-rotating rising stem valve, with working pressures to 20,000 psi (1379 bar). This diverter valve uses the Parker Autoclave tubing in sizes ranging from 9/16"" to 1"". Diverter valves provide the ability to direct incoming flow to one of two outlets. Flow is changed by rotating the handle in or out causing a double-ended stem to block the flow path to the outlet not needed.

分流阀消除了对多个阀的需求，并且消除了流向变化的可能性。20DV系列使用Parker Autoclave Engineers的中压接口。锥形和螺纹连接提供了可靠的气密密封，可在各种应用中提供可靠的性能。Diverter valves eliminate the need for multiple valves and the possibility of error in flow direction changes. The 20DV series uses Parker Autoclave Engineers' medium pressure connection. This coned and threaded connection provides a reliable bubble-tight seal for dependable performance in a variety of applications.
