Ball Valves
Fully welded ball valves
| Application: | fully welded / two and three piece design |
| Nominal Diameter: | DN 3 - 900 mm / 1/8 up to
36 inches (bigger diameters on request) |
| Nominal Pressure: | up to PN 800 mm / ANSI Class 150 - 2500 |
| Temperature Range: | -180°C to +650°C / -292°F to +1200°F |
Application:
Our fire-safe ball valves have been designed
that in case of fire, metallic seal seats, together with heat-resistent
materials, will provide an emergency sealing. This guarantees safe operation in
emergencies even at temperatures above +650°C.
In compliance with the specifications of BS 6755, section 2, 1987, our ball valves were tested by the independent Soba Test Institute and are allowed to be classified as fire-safe.
Due to this classification, our fire-safe type ball valves can be used in, among others, the petrochemical and gas industries
Our all-gas ball valves have been tested by DVGW Deutscher Verein des Gas- und Wasserfaches e.V. (German Gas and Water Industrial Association) and certified to standard. Up to 4 bars according to DIN 3537, as HAE with testing for 650°, up to 16 bars according to DIN 3547, more than 16 bars up to 100 bars according to DIN 3437 with TÜV testing of structural members.
Identification: DIN-DVGW mark with registration number.
Thus, our ball valves manufactured from suitable materials for body, ball and seals, can be used for all gases according to the DVGW work-sheet G 269/I.
Requirements and tests according to DIN 3230, section 5, are complied with.
Our ball valves for acetylene have been tested by BAM Federal Institute for Material Testing and meet the requirements for shut-off devices for high-pressure-acetylene pipes, by withstanding the forces of detonation of acetylene decay in completely open as well as closed position.Thus ball valves are applicable for shut-off devices and as quick-acting ball valve for acetylene plants in accordance with TRAC 204 and 206 technical standard.
Our Ball valves for oxygene
are constructed to meet the generally recognized technical regulations and
prevent burnout. Qualification and applicability for oxygen pressure of up to 40
bar as well as temperatures up to +60 °C have been certified by BAM Federal
Institute of Material Testing.
Marking: Name plate blue / free of oil and grease
Thus Ball valves can be used as stop valves for oxygen plants and oxygen lines according to accident prevention rule 44.0
Our ball valves for gas and hazardous liquids have been component tested by the RW TÜV according to the VdTÜV instruction sheet 1065By being awarded the component identification sign by VdTÜV, our ball valves meet the following requirements from German official guiding rules and standards:
Thus, ball valves made from suitable materials for body, ball and seals, can be used for flow media within the scope of application mentioned before
