Product Description
AGB's comprehensive accessories range ensures every valve installation is complete, safe, and operable. From gear operators for large-bore manual valves to stem extensions for buried or insulated pipelines, each accessory is engineered to match the valve's pressure class and service conditions.
Gear operators are available in bevel, spur, and worm drive configurations, sized to provide the correct mechanical advantage for manual operation of large-bore or high-pressure valves. All gear operators are supplied with position indicators and locking provisions as standard.
Stem extensions allow valve operation from grade level or from outside insulation, with lengths up to 6 metres available. Interlock systems both mechanical key and trapped key types provide additional safety for critical isolation points where operational sequence must be enforced.
