Kerotest Clears the Air with Steam
Valves Steam valves don't have to leak. They don't have to be difficult to install.
And they don't have to require any regular maintenance. Kerotest manufactures
the Gate and
Blowdown valves that
will forever clear the air.
We took our proven Model 1 Gate Valve and re-engineered it for steam
service applications. The result is a leak-proof, compact, non-rising steam
valve that needs no lubrication or adjustment.
The new Kerotest Globe Blowdown Valve combines the best globe valve
technology with a non-rising stem design to produce a valve that lets you both
throttle the steam and shut it off completely. Both new valves are
American-made, adhering to the strict quality standards you have come to expect
from Kerotest.
Replace your leaky, inefficient steam valves with Kerotest leak-proof
valves. It's the cost-effective way to cut steam losses, improve operating
efficiency and reduce maintenance costs.
Gate Valve ****
Engineered Not To Leak **** Kerotest's steam service Gate Valve features a patented packing, which
incorporates a secondary back-up seal for leak-proof performance. A low profile
design and non-rising stem make the Kerotest Gate Valve easy to install, even
where other valves won't fit. And, the valve is maintenance free, requiring no
regular lubrication or adjustment of any kind.
Features and Benefits:
No Gland Tightening
Full Opening --- no significant pressure drop
Low Operating Torque
Patented Packing --- no environmental leakage
Back Seat --- full containment of pressure below packing
Weather Seal Protection
All valves receive 100% Full Rating Hydro Seat Test, 150% Full
Rating Hydro Shell Test, and 100 PSIG Air Seat Test

Globe Blowdown Valve **** Combines Throttle & Shut-Off **** The Kerotest non-rising stem Globe Blowdown Valve combines both a throttle
valve and a shut-off valve in one low profile, compact design. In addition to
dependable shut-off, the Kerotest Globe Blowdown Valve utilizes a tapered
throttle disc design that allows precise control over a wide range of flow
conditions. Kerotest's Globe Blowdown Valve features a unique non-rotating
tapered disc design to achieve constant disc to seat line contact. The disc does
not rotate while in contact with the seat, thus minimizing seat and disc wear,
and reducing costly maintenance and valve replacement.
Features and Benefits:
Stainless Steel Tapered Throttling Disc is fully
stellite hardfaced where exposed to flowing media
Valve Body Seat and Seat Bore are fully hardfaced
Non-rotating Throttle Disc design improves valve's long term
shut-off performance
Redundant Stem Packing Chamber requires no maintenance or
adjustment --- eliminating costly steam leakage problems
Combined Throttle/Shut-Off Design eliminates need for additional
upstream isolation valve
