Beswick Engineering Co., Inc.
Slide Sleeve Valve, 10-32 Thread, Venting Beswick's miniature MSV slide sleeve valve provides an efficient in-line three-way valve. When the sleeve is moved to the "ON " position, fluid is allowed to pass through the valve. When the sleeve is moved to the "OFF " position, the outlet is exhausted to the atmosphere and fluid is prevented from exiting the inlet port. The valve can be attached directly on a device to be isolated and does not require mounting. The maximum pressure rating of the valve is 200 psig and the flow restriction...

Festo Corporation
EGSL Series Electric Slide inches (300 mm). The enclosed ball screw prevents dirt or small work pieces from entering the guide area. Based on the high-precision guide of the DGSL, the pneumatic equivalent of the EGSL, these electric slides are available in four sizes as measured in slide width: 1.4, 1.8, 2.2, and 3 inches (35, 45, 55, and 75 mm). The motor, which is matched perfectly to the mechanical components, does not project beyond the slide. It can be mounted axially or in parallel. This results in a rectangular... (read more) -
