4″ Side Discharge Valve – 90 Degree Stub Outlet with Extension Tube

The Betts’ Side Discharge Valve is a manual external stop valve designed to facilitate front pump-off applications for hot product tanks.  The valve body is welded directly into the side shell of the tank which allows the seat and surrounding area to be fully heated by the elevated temperature of the product.  Internal pump-off piping is welded to the rear inlet port of the valve.  The front extension tube is provided to accommodate tank insulation yet keeps the top-head and bonnet area open for inspection and maintenance.

Valve MAWP: 10 psig [.69 bar]
Minimum bursting pressure: 100 psig [6.9 bar]
Max. Temp. of Aluminum Valve: +400°F [204°C]
Max. Temp. of Steel Valve: +500°F [260°C]

The Side Discharge Valve’s outward opening disc and unobstructed flow path is ideal for heavy, viscous, temperature-sensitive commodities.  The stem and stem nut utilize ACME threads and a grease fitting for exceptional service life.  The external packing gland allows for easy adjustment of the packing to ensure proper sealing.  A caution label explaining the packing gland adjustment is included with the valve and should be located close to the valve in a conspicuous area of the tank.  An optional piercing lance can be specified to aid flow by breaking away semi-solidified product heels.
