threads. The duplex bushing is used to ect 2" pipe to dual 1/2" or 3/8" lines. 0 Ix is MW Solenoid Valve—FIG 710 Installed on pipeline leading tolfrom an aboveground tank. This valve is used to prevent accidental spill or siphoning of product from the tank in the event of a fracture in the pipe or other cause for leak downstream and below the liquid level. The Fig. 710 solenoid valve is a two-way, hung piton type valve with normally "closed at rest positioning." The valve opens upon receipt of an electronic signal such as when a dispenser or pump is switched on. Download Specification Sheet pdf 1/4" Expansion Relief Valve—FIG 77 Used on AST piping for relief of excessive pressure due to outside temperature rise. Valve allows product to return back to storage tank. Especially suited for existing pipeline and by- passing a valve that does not have expansion relief. Brass construction. 1/2" Expansion Relief -FIG 78DI Used on AST piping for relief of excessive pressure. Valve allows product to return back to the storage tank. Ductile Iron construction. '7 __W Gate Valve (without expansion relief)—FIG 234 and 235 Rising Stem Gate Valve used for manual flow control in petro -chemical liquid handling. Available in brass and ductile iron. This gate valve operates by rotating handwheel counter -clockwise to open or clockwise to close. Valve can be left partially open to control flow rate. Gate Valve (with expansion relief) --FIG 534 and 535 Rising Stem Gate Valve used for manual flow control in petro -chemical liquid handling. Available in brass and ductile iron. This gate valve operates by rotating handwheel counter -clockwise to open or clockwise to close. Valve can be left partially open to control flow rate. This valve is equipped with expansion relief. This means that the piping exposed to outside temperature rise will create pressure build-up in sections of piping that are isolated by closed valves for example. Expansion relief feature allows product to bleed back through the closed valve, and thereby relieving excessive pressure in the line. If left uncontrolled, pressure build-up within a system can result in a release of product to the outside.

They have a pressure rating of 200 PSI WOG, cold, non -shock. Ball Valve (full part)—FIG 691 Full port ball valve used for liquid handling with manual open -close in quick quarter -turn handle operation. Threaded (NPT) connections. Valve can be operated in partial open position. Lockable with padlock.
