Parker Instrumentation has launched a miniature 12-mm/1/2-inch ball valve for fluid instrumentation applications, made of 316 stainless steel. Thanks to a patented one-piece seat and packing component, the valve operates over an exceptionally wide temperature range. The moulded one-piece seat/packing component eliminates “dead space” between the valve and the inlet/outlet connections which can trap particles or build up deposits – as well as a potential leak path. Combined with the valve’s miniature design and integral compression tubing connections, which together cut weight and space substantially compared with conventional products, instrumentation engineers have an extremely versatile product which brings new performance to all ball valve applications including high purity sectors such as bio-pharm and semiconductors.
Designated MB8, this 0.406-inch/10.3-mm orifice valve offers a high flow co-efficient (Cv) of 6.42 and is rated for 2500 PSIG/172 bar operation. Fabricated from 316 stainless steel, it is available in a three-way configuration, or either in-line or angle two-way configurations. The product completes Parker’s popular MB Series of miniature ball valves, adding a high flow option to complement design options for tubing sizes down to 1/16-inch/3-mm.
The valve’s ball construction is designed for fast-acting inlet, isolation or directional control of liquids or gases, operated by a quarter or half turn depending on the port configuration. Compatible pneumatic actuators are available for automated applications.
