Needle Valve, Diverter 20DV Series - 20,000 PSI

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'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.

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.
