AVCO 1500 Series – 1/4" 3 Piece, Full Port, Cryogenic Ball Valve (Made in USA)

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 cryogenic 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 is sealed twice – once at the top of the valve and again at the top of the bonnet. Sealing occurs at the thrust washers inside the body and bonnet to reduce the potential for leakage. The upper mount pad complies with ISO 5211 and provides positive travel stops and lock off. The encapsulation of the seat also gives an option for fire safe trim that meets API 607. Inter-changeability enables this valve to be supplied as a L-port cryogenic diverter valve with bottom or side entry ports or as a Vee ported cryogenic control valve. Ideally suited to the aerospace, petrochemical, liquid nitrogen (LNG) and liquid oxygen markets, this valve will meet all your requirements.
