Valves For Liquid Level Gauges - KTV Tubular Valves
APPLICATION:
The KENCO Tubular Valve (KTV), when used with a KENCO "SAFEGUARD" level gauge or KENCO "EPG" level gauge, provides maximum operator safety and environmental protection from a potential gauge glass failure. The KTV is designed for service in low to medium pressure applications up to 500 psig.
FEATURES:
-
The 1/8" thick o-ring provides for easy installation of the glass and requires less wrenching of the packing nut to seal
-
Positive O-ring seal gauge glass connection
-
1/2" OR 3/4" MNPT rigid vessel connections
-
Ball check shut off
-
Inline vent and drain connection for easy glass cleaning
-
Straight pattern design
-
Braided PTFE stem packing
-
Flanged vessel connections available
-
All valves are supplied with 316 S.S. valve stems, ball checks and glass packing washer
-
The bodies are precision cast investment castings with each body pressure tested to assure quality
