The Figure 350 Air Cushioned Outside Lever & Weight Swing Check Valve is standard with ductile iron body and cover rated for 250 PSI (1,274 kPa) working pressure from 3” (DN80) to 30” (DN750) size, bronze body seat, stainless steel hinge shaft and rubber faced ductile iron disc for drop tight shutoff. A side-mounted totally enclosed stainless steel air cushion chamber minimizes the noise associated with the valve’s rapid closure. The Figure 350 meets the standardized face-to-face length of AWWA C508-01. It is suitable for water, wastewater and raw sewage in horizontal or vertical installations.
Figure 340-S Outside Lever & Spring Swing Check Valve
The Figure 340-S is standard with ductile iron body and cover rated for 250 PSI (1,274 kPa) working pressure from 3” (DN80) to 30” (DN750) size, bronze body seat, stainless steel hinge shaft and rubber faced ductile iron disc for drop tight shutoff. The lever & spring can be adjusted to close the valve even more quickly than the lever & weight. The Figure 240-S meets the standardized face-to-face length of AWWA C508-01.
Figure 340-W Outside Lever & Weight Swing Check Valve
The Figure 340-W is standard with ductile iron body and cover rated for 250 PSI (1,274 kPa) working pressure from 3” (DN80) to 30” (DN750) size, bronze body seat, stainless steel hinge shaft and rubber faced ductile iron disc for drop tight shutoff. The lever & weight provides a quicker closure and is less likely to be slammed shut than a plain check valve. The Figure 240-W meets the standardized face-to-face length of AWWA C508-01.
