SEALS FOR STEAM VALVES
Sealing can be done with closed sealing rings made of e-graph foil by pressing in the tool to the required dimensions which are combined with anti-extrusion sealing rings made of mechanically reinforced packings or by making them from expanded graphite packings pre-pressed in the tool to the required dimensions - with anti-extrusion sealing rings made of mechanically reinforced packing. The operating parameters and the condition of the sealing surface decide on the method. 99.85% purity e-graph foils, e-graph packing with anti-corrosion inhibitor, sheets 1.4404, springs 1.4571 are used for production.
Area of application: -200 / + 500 ° C, superheated steam +650 ° C, pH 0-14, max. pressures up to 500 bar, and more, depending on the type of i p x t, density: 0.7 -1.0 gr / cm³ for raw material and 1.2-1.9 gr / cm³… directly depends and is determined according to the maximum p x t
- We make sealing rings / sets according to the given dimensions regardless of the working conditions
- short delivery times
- reliable and economical solutions
- no limit in operating parameters (p, t)
- stocks of standard dimensions for steam valves, pumps, ejectors (soot blowers), turbine plants, ...
