O-rings are available in various elastomeric materials.  Versa offers a host of different O-ring and seal material options to create the most suitable match of the elastomer to the specific application.  The media, ambient conditions, lubrication and cycle rate affect the integrity and longevity of the O-ring.  In ideal conditions, O-rings can and will last 10 years or more.  Versa advises its customers to consult their local authorized Versa distributor to ensure proper O-ring selection and to develop a proactive maintenance schedule for your application.

Most vacuum applications use a 3-way, 2-position, normally open valve. The vacuum pump is connected to the valve’s exhaust port, the suction cup is connected to the cylinder “A” port and the inlet port is left open as a vent. Although the valve is a normally open valve, in a vacuum application it performs as a normally closed valve.

Reversing the flow through a V&T series valve may result in the valve not functioning correctly because the internal seals could be damaged. Please see “The Anti-Extrusion Principal.” Please note there may be options or other products that may be right for your application.
