TRIM TYPES DESCRIPTION/ APPLICATION One Stage Hush trim is a specialty trim designed to reduce noise associated with compressible fluids as well as to reduce the undesirable effects of flashing and cavitation that would occur with most single pressure drop trims. The Hush cage consists of a single cylinder with a large number of radially drilled orifices. The fluid exits the orifices as low energy jets resulting in significant reductions in noise or erosion. Although numerous standard designs are available, One Stage Hush is often custom engineered to provide various flow characteristics or...

SERIES 700 ACTUATORS Series 700 actuators are pneumatic diaphragm operators that have spring return in both direct and reverse acting styles, offering fail open and fail closed models respectively. The pressed steel diaphragm case construction along with the nylon reinforced Buna-N rubber diaphragm permits a maximum allowable air supply pressure of 80 psig (550 kPag). This pre-formed diaphragm provides a constant effective area throughout the full extent of travel. With effective diaphragm areas ranging from 60-160 in2 (385-1030 cm2). Series 700 actuators can provide the necessary stem...
