The Bray/VAAS Series 770 is a bidirectional o-ported slide gate valve, designed for severe service applications. The 770’s o-ported gate is in constant contact with the seats, minimizing seat stress and ensuring maximum sealing performance. The durable ductile iron body is offered in a compact wafer style. When fully open, the valve is full bore,
offering no resistance to line media
