An improved diaphragm valve, particularly adapted for applications at high pressures and in applications in which low dead volume is required. The valve has a diaphragm which is formed of a halogenated hydrocarbon polymer of a compression strength sufficient to avoid non-recoverable extrusion of the diaphragm. Use of such a valve totally avoids the work-hardening problem encountered in use of valves using metal diaphragms.
