1 MWA /MWB For working pressures up to and bar Catalogue HY7-/UK June

2 Catalogue HY7-/UK Introduction Standard MW Cylinders Parker's MW range of cylinders is designed for medium and heavy duty industrial and mobile applications. Two versions are available; the MWA Series for use at working pressures up to bar, and the MWB Series for bar applications. The MW range of cylinders is of welded construction at the cap end, with a threaded rod bearing at the head housing the gland seals. Standard cylinders are suitable for use with mineral oil, and are available in a choice of mounting styles. Custom Designed Cylinders This catalogue describes the basic range of MW cylinders; in practice, many of these cylinders are designed as 'specials' to the customer's unique specification. Some examples of these special cylinders are illustrated below. For more information, please contact your nearest Parker sales office.
