With applications including process industry, automated lab analyzers and continuous emissions monitoring, VICI Valco has introduced the Model DV22 Microvolume Diaphragm Valve.
The 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.
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.
The company also notes that maintenance procedures are greatly simplified, as the valve is held together by a single screw and locating pins insure proper alignment.
Now that carbon dioxide (CO2) monitors are legislation in most countries and laws are in place in all states in the US since a while back, it is important to know how to live with them and how to make a ‘calibration’ or check-up of the functionality of the sensors. ...
