Product overview
Sigma tubular gauge assemblies pair two steel gauge cocks, preferably forged, with a borosilicate glass tube protected by four guard rods or two C protectors. They are a simple, economical way to see the liquid level on tanks and vessels at moderate pressures.
Built for safety
The gauge cocks have union bonnets, stainless steel trim, screwed renewable seats and stainless steel ball checks that shut off the process fluid automatically if the glass breaks. An extension tip on the stainless steel stem unseats the ball check when the valve is closed.
Union connections at the valve ends make assembly and installation easier, and stuffing box glass connections with a packing bush keep twisting stress off the tube when the gland nuts are tightened. The cocks are operated by handwheel.
