Mini Diaphragm Valve requires minimal maintenance.
Press Release Summary:
Using 3-way solenoid for actuation, Microvolume Diaphragm Valve is available in 3 configurations: 4-port internal loop sample injector; 6-port external loop sampling/switching valve; and 10-port multifunctional diaphragm valve. Actuator air ranging from 40–50 psi is supplied to side port with 10–32 female threads, permitting use of various compression or barbed fittings. Lifetime can exceed 1,000,000 cycles at ambient temperature/300 psi or 500,000 cycles at 175°C/300 psi.
Original Press Release:
Model DV22 Mini Diaphragm Valve
VICI’s Microvolume Diaphragm Valve 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 4 port internal loop sample injector; a 6 port external loop sampling/switching valve; and the industry’s first 10 port multifunctional diaphragm valve.  Â
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 3-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.  Â
