DescriptionStainless steel wire screens are mounted within the precision orifice assembly to protect the orifice from contamination that could be introduced during handling or in-stallation. The fine screens are not intended to replace normal filtration equipment, but rather to augment the protection of small orifices.
ApplicationsThe integral screen/orifice assembly pro-vides a compact arrangement.Type BS and ES – The screen protects the orifice from particles in the pressur-ized fluid.Types BMMS, QS, QXS – The screen protects the orifice from particles that could migrate from outside, when there is no fluid flow.Type US – The dual screen protects the orifices from particles that could enter in either direction..

Miniature In-Line Screens38
DescriptionFine screens are used to protect orifices and other critical components from the occasional particles that enter the fluid during installation or otherwise. They are not intended to replace normal filtration equipment, but rather to augment the protection of critical components in fluid control systems.Four sizes of screen particle retention are offered; 10, 15, 25 and 100 microns. The stainless steel wire screens do not intro-duce loose particles into the fluid stream. The screens are thoroughly cleaned to prevent inadvertent introduction of con-taminants.
ApplicationsIn-line screens are suitable for use with liquids or gases compatible with the mat-erials of construction. The screens protect critical components such as orifices from clogging or reducing flow rate.Applications for in-line screens include protection of:• Precision Orifices• Pneumatic Transducers• Gas and Liquid Flow Instruments• Medical Devices• Filling and Purging Systems• Pneumatic Timers• Transmitters• Pneumatic Transmission Lines• Hydraulic Controls• Leak Test Equipment• Flow Measurement Devices
FeaturesThe in-line screen products are all metal; the screen material is made from fine stainless steel wire.
• Particle retention size as small as 10 microns• Miniature fittings and screens • Clean assemblies• No loose fibers or particles• Long life screen material• Well defined flow characteristics• Compatible with standard 10-32 and NPT

InstallationMethods
To install a press fit sleeve for securing a screen in position, it is good practice to have the shoulder diameter D2 less than 70% of the press fit diameter D1. The inner di-ameter of the sleeve should also be less than 70% of D1.
To install a screen where D2 is greater than 70% of diam-eter D1 first install a washer in which the inner diameter D3 is less than 70% of D1.and then secure the screen with a sleeve which has an inner diameter that is less than 70% of D1.
