TUBE-TYPE SIGHT GLASSES

GENERAL INFORMATION FOR ASSEMBLIES ON THESE PAGES:

• All PRESSURE RATINGS are subject to the limitations of the tubular gauge glass, also pressure ratings decline as temperature rises.
• All TEMPERATURE RATINGS are subject to the limitations of the gaskets.
• All Valve Sets are furnished LESS GLASS AND RODS unless specified.
• These Value Sets can be supplied with the following

TUBULAR GAUGE GLASSES
Cat. 505 – Clear
Cat. 506 – Red Line
Cat. 507 – Extra Strength
Cat. 508 – Red Line X-Strength

• Gaskets Materials vary from Valve Set to Valve Set. EPMD is superior for water and steam, Neoprene is superior for petroleums and Teflon® has highest temperature rating and superior chemical resistance.
STUFFING BOXES are designed to assure positive seal with minimum compression of the packing and are provided with a packing gland or washer to prevent torsional stress on glass when packing nuts are tightened, plus they add protection against packing blow-out.
THE AUTOMATIC BALL CHECK feature prevents spraying the operator in the event of glass breakage. The sudden rush of the Liquid will push the Balls to their seats thereby shutting off the liquid.
GAUGE GLASS PROTECTORS for extra protection for the Tubular gauge glass are available.
• There will be a BOXING CHARGE for all shipments over 6 ft. and for all Export Shipments.

NOTATIONS:

a. Automatic Ball Checks: Rolling Ball in Upper & Lower Valve Bodies (Non-ASME).
b. Automatic Ball Checks: Rolling Ball in Upper Valve Body, Rising Ball in Lower Body (Non-ASME).
c. Automatic Ball Checks: Rolling Ball in Upper Valve Body, Rising Ball in Lower Valve Body (ASME).
d. All Valve Sets with Automatic Ball Checks can be made “non-automatic” by removal of the Balls.
e. Higher temperature ratings are attained with higher temp-rated gaskets.
f. Lower Valve Body has Hand-wheel shut-off, Upper Body has no shut-off.
m. Teflon™ gaskets are not (hard) solid. They are a softer gasket made of a composite of Teflon™ and other materials for better sealing. (Ref: Cat. 556.)
n. Lower Body has 3-way Drain Valve for opening and closing Valve and Drain.
