These sub-miniature ball valves are offered in two standard configurations. The MBV-1010-303 is the answer for designers requiring an On/Off valve, while the MBVT-1010-303 is for applications requiring the selection of one of two possible flow paths. These valves weigh only 9.0 grams and 12 grams respectively and save space. In both models, the valve housing is made from 303 Stainless Steel (with a 316 Stainless Steel ball) for improved corrosion resistance. The seal material is Buna-N. EPDM and fluorocarbon (Viton) are optional. All ports are tapped 10-32 UNF. Typical applications are from 0 to 250 psi.
