closure regardless of viscosity. For viscosities greater
than 20,000 SSU, do not use a dashpot washer.

Flanges (Figure 5) are offered in 1½ and 2 inch BSPT
and NPT sizes and weld types. Materials of construction
are aluminum, brass, cast iron, and stainless steel.

accessories used when normal manual ON and OFF
valve operation is desired. Different handle and linkage
