Beswick’s miniature ball valve is an excellent choice for applications requiring a compact on/off valve. This design offers small size, light weight, and increased flow over the 10-32 MBV design. A few years ago, Beswick introduced the smallest 10-32 threaded ball valves in the miniature fluid power industry. Beswick has a tradition of design innovation dating back to the 1960s and is well respected for building excellent “mousetraps” in terms of fluid power products. These 10-32 threaded ultra-miniature ball valves offer many advantages.

The MBVMD-1010-303 ball valve is a suitable solution formany miniature high technology type applications. You can think of it as the “baby bear” of ball valves. There are times, however, when you need a precision ball valve that is more compact than traditional NPT threaded ball valves but can also provide more flow than is possible with 10-32 threads and a relatively small orifice. That configuration is not easy to find.

The Beswick MBV-1414-3 ball valve is designed with ¼-28 UNF straight threads and a relatively large orifice diameter of 0.125 inch. It weighs only 34 grams. That isn’t much yet it provides more than 3 times as much flow area as the 10-32 threaded MBVMD-1010-303. You can think of the MBV-1414-3 as the “father bear” of miniature ball valves. Maximum supply pressure is 250 psig.

A Teflon seat is used to seal the ball on all configurations. All configurations also contain one o-ring seal. The standard o-ring seal material is Buna-N. Optional materials include EPDM, Viton and Silicone.
