Glass-Trac Type 1 & 2 Offset Gage Valves are available with screwed (S), union (U), (illustrated below) and tubular (T) gage connections (Page 15). Both 1 and 2 Valves are used with Reflex and Transparent Gages in working pressures up to 4000 psi and with Tubular Gages to their maximum rating. The Teflon packing ring is standard and used in services up to 450º F. For temperatures to 700º F, valves are fitted with special wire graphite packing. Both valves have stainless steel ball checks to shut off the flow automatically in case of gage glass breakage.
The “offset” feature permits easy cleaning of gages.
A floating tailpiece on Type 1 valves permits an overall vertical adjustment of 1/8” if the gage center-to-centers are not precisely located. Installation is quicker and gage strain is eliminated.
Type 2 Valves have an optional backseating stem allowing the packing to be changed without shutting down the vessel.

The Glass-Trac Type 3 Offset Gage Valve has the Outside Screw & Yoke design which prevents excessively hot and corrosive fluids from contracting stem threads, causing possible malfunction. The stem backs directly off the regrindable valve seat using the positive, non-rotating stem principle. The valve is offset for ease in gage cleaning and comes in both screwed (S) and a union (U) gage as standard. On special order, tubular (T) gage or other type connection can be supplied.
Type 3 valves are used with Reflex and Transparent Gages in working pressures up to 4000 psi.
The standard tank connection for Type 3 OS&Y Offset Gage valves is a ¾” NPT solid shank, with optional ½” and 1” NPT sizes. Ends beveled for welding also are available. Valve materials include forged carbon steel and 316 stainless steel.
A molded Teflon packing ring is standard at no extra cost in valves for services up to 450º F. For temperatures to 700º F, valves have wire-graphite packing. The Type 3 valve has stainless steel safety ball checks to shut off the flow automatically in case of gage glass breakage.

The Glass-Trac Type 7 Offset Gage Valve features the Outside Screw & Yoke (OS&Y) design which prevents excessively hot and corrosive fluids from contacting stem threads. The stem uses the positive non-rotating stem principle and backs directly off the regrindable seat. This valve is offset for ease in gage cleaning and is available in screwed (S) and union (U) gage connections. The Type 7 Valve also has a backseating stem as a standard feature. Stainless steel ball checks are available upon request.

The Glass-Trac Type 4 Straight-Thru Gage Valve is available with screwed (S) and Union (U) gage connections and used with Reflex and Transparent Gages in working pressures up to 4000 psi. The “straight-thru” valve body design is popularly used with close hook-up (side connection) gages because the gage side connection centers and vessel centers can be identical. (With offset valves, vessel centers must be inside or outside side connection centers.) Type 4 Valves have a ¾” NPT Male Tank Connection as standard, with other connections available on order.
Type 4 Straight-Thru Gage Valves are stocked in carbon steel with stainless steel trims. A molded Teflon packing ring is standard at no extra cost in valves for services to 450ºF. For temperatures to 700º F, valves have wire-graphite packing. The Type 4 Valve has stainless steel ball checks to shut off the flow automatically in case of gage glass breakage. An optional back seating stem is available on request.

The Glass-Trac Type 5 Gage Valve has the Outside Screw & Yoke design which prevents excessively hot and corrosive fluids from contacting stem threads, causing possible malfunction. The stem backs directly off the regrindable valve seat using the positive, non-rotating stem principle. The valve has a “straight-thru” body design and, with an optional bleed valve, can be used in a block and bleed application. Standard gage connections are screwed (S) and union (U) but any other type connection can be supplied on special order.
The standard tank connection for Type 5 OS&Y Straight- Thru Gage Valves is a ¾’ NPT solid shank, with optional ½” and 1” NPT sizes. Ends beveled for welding also are available. Valve materials include forged carbon steel with stainless steel trims. A molded Teflon packing ring is standard at no extra cost in valves for services up to 450ºF. For temperatures to 700ºF, valves have wire-graphite packing. The standard Type 5 Valve has a back seating stem that allows the packing to be changed without shutting down the vessel. Stainless steel ball checks are available upon request.

TUBULAR GAGES AND VALVES
Glass-Trac Tubular Glass Gages are available in any length desired and can be fitted with Type 1T or 2T Gage Valves (see Page 18). These gages provide 360º visibility of the liquid level through strong, clear glass. Tubular glass is used in three types: Red Line, High Pressure and Heavy Wall. Pressure ratings are different for each type and also depend upon glass length (see next page). If glass breakage occurs, a stainless steel ball check shuts off each valve. Glass tubes should be cut 1½” shorter than valve center-to-center. The resulting visible glass length is 5” less than the valve center-to-center.
Red Line glass provides a bright crimson stripe against a narrow white strip throughout the length of the tube. Liquid levels are easy to see against this special optical effect. The glass is heat-resistant and ends are fire polished. Red Line is available in both ⅝” and ¾” O.D.
High Pressure glass is a versatile, medium-strong type of tube used in many applications. It is crystal clear and ends are fire polished.
Heavy Wall glass has the highest pressure rating of all tubular glass. It is extremely clear, corrosion resistant, will not scratch easily and is extra resistant to heat shock. Ends are ground.
Four carbon steel guard rods and two guard rod rings are used to protect tubular glass gages. The rods are anchored in each ring which is fastened to the valve behind the union nut. Rods should be cut 1¾” shorter than valve center-to-center. A transparent plastic sheath also is available to clamp around the glass tube. Sheath length should be 4 ⅜” shorter than valve center-to-center. Also available is an expanded metal gage glass protector for additional protection of the glass. Specify gage valve center-to-center for proper sizing of this assembly.
⅝” O.D. Glass Standard, ¾” O.D. Glass Optional
TUBULAR VALVES (BRASS)
For low pressure water vessels, storage tanks, containers, etc., Glass-Trac provides Type OT Brass Valves for Tubular Gages. The valves are made up with 5/8” O.D. Pyrex Red Line, High Pressure or Heavy Wall Glass from stock. Each valve contains a brass ball check which closes the valve in the event of glass breakage. Two guard rods are used. The lower valve also is fitted with a threaded drain cock. Type OT Brass Valves are suitable for working pressures up to 200 psig at or under 400ºF.
Tubular glasses are available in any length and should be cut 1½” shorter than
valve center-to-center. Guard rods should be ¾” longer than the valve centerto-centers.
Visible length is 3” less than the valve centers.

Glass-Trac Offset Tubular Gage Valves are identical to Type 1 and 2 S and U Valves except they are fitted with the ⅝” O.D. tubular glass connection. The Type 2T Valve also can be furnished in the coarse thread design and with quick-operating lever for remote operation by chain. Both valves have a molded Teflon packing ring and rubber glass gaskets as standard for services up to 250º F. For temperatures to 425º F, valves have wire-graphite packing
and Viton® glass gaskets. In the event of tubular glass breakage, a stainless steel ball check closes the valve to prevent further loss of fluid.
