Yarway 6978-6954 1-1/2 1056876

The Yarway unit tandem valve features a one-piece steel block which serves as a common body for both blowing and sealing valves. This construction eliminates interconnecting welds or bolts and gaskets where flanged valves are required and makes the unit tandem a compact design. For valves with basic pressure rating to 600 psi (medium pressure unit tandem), the inlet valve is a hardseat type and the discharge valve is of the seatless type. For basic pressure ratings above 600 to 2500 psi, both inlet and discharge valves are hardseat type. All features of the Yarway single valves are contained in the unit tandem design with the additional advantage of a one-piece, heavy- duty construction.
