High Pressure Seals With Back-up Rings
A number of design options are available for high-pressure sealing problems. Back-up rings can be configured into most seal types to prevent extrusion of the jacket material. Pressure actuated back-up rings are often recommended for closing multiple gaps or for dealing with hardware sideloads.
Belleville Spring Seals ߿
Face seals energized with belleville washers provide high deflection without risk of the spring collapsing. Another advantage of bellevilles is that they can be manufactured in smaller diameters than most spring energized seals.
Sanitary Seals ǰ Ǿǰ
The RS and JS designs shield the spring from the media to prevent entrapment in the spring and allow easier cleaning. Excellent in food filling and other dispensing equipment.
Bi-Directional Seals ̵ /
This versatile design combines two seals and a guide bearing into a one-piece component. The bi-directional seal is found in moderated temperature/pressure applications where simple assembly and quick replacement are required. This design (without an inside diameter) also serves as a floating piston.
Miniature Seals ʼ
Furon's design and manufacturing capabilities extend to extremely small diameters and cross sections. They are incorporated into any application for which apace is at a premium and precision is a must. Commonly found in medical tools and analytical equipment.
URS Seals
Seals with more than one energizer are recommended for retrofitting large cross section glands to maintain adequate sealing on both the I.D. and O.D. This design strategy is used in many of Furon's big diameter seals where large cross sections are common.
Ball Valve Seals
Ball valve seals are machined to the exacting tolerances called for by manufacturers. A highly successful example of this type of seal is the anti-blowout seal, which is used in petrochemical valves. Our engineers will assist you in designing a captive anti-blowout feature into your hardware as shown below.
