JGFOTHER SEALS

JGF
The profile JGF is an axial single acting flange seal for external pressure that is most suitable for static and quasi-static applications. It consists of an U-shaped PTFE jacket and a V-shaped corrosion resistant spring. The spring makes the seal permanently elastic, independent of operating temperature changes, pressure, etc. The JGF sealing replaces in many cases the conventional O-ring-back-up-ring-combination.

ADVANTAGES ARE
- resistant to most fluids and chemicals
- high seal pressing
- high and prolonged recovery
- very good tightness and impermeability
- easy installation
- broadly based application scope by a tall variety of materials
- excellent resistance to ageing
- unlimited shelf life

APPLICATION RANGE

working pressure:  static 80 Mpa (800 bar) dynamic 40 Mpa (400 bar)
working temperature:  - 200 °C up to + 260 °C
surface Speed:  static up to slow rotations and swiveling movements
media:  almost all fluids, chemicals, and gases

A large application scope is given by the variety of combinations of the sealing and spring materials (for example the possible sterilization). It can be applied in apparatus engineering and plant constructions, pharmaceutical processings, cryogenics, food and beverage processings, nuclear energy technologies, aeronautics, vacuum processings as well as natural gas and mineral oil machineries. This data represents the maximum limit of strength and is closely interrelated. Under difficult conditions it is not advisable to make use of all values simultancously at maximum limit.

MATERIAL

joint washer: PT012
spring: Stainless steel 1.4301 (AISI 301)


ORDER EXAMPLE
Inner groove diameter: 50 mm
JGF 0500 PT033 3820 C

JGF = Profile
0500 = Rod Ø x 10
PTO33 = Compound
3820 = Serial number, Last two digits: spring code
C = Cross section

MOUNTING INSTRUCTIONS
For special applications it is recommendable to use a sealing cross section, reduced or stepped up, that differs from standard. In these cases replace the standard cross section code (e.g. "C") by the desired one (e.g. "B" or "D").
For special cases of application (high temperatures, speed, specific pressure, use in water, HFA-, HFB-fluids etc.) please contact our consultancy Service.
