The AVCO 1500 series ball valve brings all the features and benefits of our 1100 series valve to the cryogenic market. Designed in accordance with ASME B16.34 it incorporates a single piece cryo bonnet extension bolted to the main valve body. The valve is available off the shelf or with customized bonnet lengths to give greater flexibility and ensure the operator is at a sufficient distance from the pipeline. The seal between the bonnet and valve is achieved with an engineered Flexitallic spiral wound gasket.
The cryogenic bonnet houses an extended stem and, unlike most valve manufacturers, the valve stem has double packing/sealing whilst maintaining blow out prevention. The upper mount pad complies with ISO 5211 and also gives positive travel stops and lock off.
Inter-changeability enables this valve to be supplied in three (3) way versions with bottom or side entry ports and as a Vee ported cryogenic control valve.
Ideally suited to the aerospace, petro-chemical, liquid nitrogen (LNG) and liquid oxygen markets, this valve meets all your requirements.
