VICI’s Microvolume Diaphragm Valve (DV22) is designed for trouble-free use in applications requiring minimal maintenance and maximum lifetime, making it the ideal choice for the process industry, automated lab analyzers, and continuous-monitoring environmental analyses. Three configurations are available: a four port internal loop sample injector; a six port external loop sampling/switching valve; and the industry’s first ten port multifunctional diaphragm valve.
Lifetime for the DV22 can exceed 1,000,000 cycles at ambient temperature/300 psi or 500,000 cycles at 175°C/300 psi. The standard valve is for applications in which the sample is above ambient pressure, but it can also be used with sub-ambient pressures, such as when the sample is pulled through the valve by vacuum.
Actuator air (40-50 psi) is supplied to a side port with 10-32 female threads, permitting use of a variety of compression or barbed fittings. A three-way solenoid is required for actuation, which may be ordered separately. Maintenance procedures are greatly simplified since the valve is held together by a single screw and locating pins insure proper alignment.
VICI’s new Pulsed Discharge helium ionization Detector (PDD) extends the detection capabilities of the popular Agilent 6890 and new 7890 GCs, with its basic operating mode capable of replacing many of the detectors currently used by gas chromatograph (GC) manufacturers.
VICI Valco’s Cheminert® C72 ultra-high pressure UHPLC injectors, switching valves, and selectors are ideal for high speed, high throughput techniques which demand a valve and fitting system that minimize internal volume and eliminate dead volume.
