Jerguson - Model V-Series -Tubular Glass Gages
Jerguson Gage & Valve offers a complete line of brass, bronze and stainless steel tubular glass gage valves for economical service. The standard straight-through flow design features a durable cast aluminum wheel. Connections of 1.2 or 3.4 inch NPT are available for attaching the valve to the vessel. Highly durable PyrexR gage glass is available with outside diameters of 5.8 or 3.4 inch. Visibility lengths vary as required. Guard rods are recommended to protect the glass from damage, and for added safety.
BRASS GAGE VALVES
Series VA Automatic
Model No.VA-991 5.8" Dia. Glass, 1.2" NPT Vessel Conn.
Model No.VA-902 3.4" Dia. Glass, 3.4" NPT Vessel Conn.
These tubular glass gage valves feature brass body construction.
They come complete with corrosive-resistant ballchecks for automatic closure in the event of glass breakage. This ensures safety and prevents the loss of fluid. Maximum working pressure is 200 psi @ 400‹F, or 400 psi @ 100‹F.
Series VB Non-Automatic
Model No. VB-991 5.8" Dia. Glass, 1.2" NPT Vessel Conn.
Model No. VB-902 3.4" Dia. Glass, 3.4" NPT Vessel Conn.
These all brass valves are similar to above models. However, ballchecks are not standard, thus making operation non-automatic. A 1⁄4" needle drain valve in the lower unit accommodates a breakage condition. Either a 1⁄4" lower arm ball valve or a petcock is available upon request. Sizes, packing materials and working pressures are identical to above models.
BRONZE GAGE VALVES
Series VC Non-Automatic
Model No. VC-991 5⁄8" Dia. Glass, 1⁄2" NPT Vessel Conn.
Model No. VC-902 3⁄4" Dia. Glass, 3⁄4" NPT Vessel Conn.
Conforming to A.S.M.E. power-boiler code requirements, these gage valves feature stainless steel ball checks in both upper and lower units. This provides automatic closure in the event of glass breakage and requires the ball check in the lower valve to rise vertically to its seat. A safety handle is also provided for manual operation of the 5⁄16 inch diameter drain valve. This valve is of the full-flow ball valve design.
The valve body is constructed of rugged, heavy pattern bronze. Standard packing materials are wear-resistant Teflon©- asbestos. Maximum working pressure is rated at 500 psi @ 500°F, or 250 psi @ 400°F.
Series VE Non-Automatic
Model No. VE-991 5⁄8" Dia. Glass, 1⁄2" NPT Vessel Conn.
Model No. VE-902 3⁄4" Dia. Glass, 3⁄4" NPT Vessel Conn.
These gage valves are identical in every respect to above models, except for the non-automatic design. Ball checks are not included.
