Piper's Kinzbach Pressure Relief Valves
UNIQUE HIGH PERFORMANCE PRESSURE RELIEF VALVE DESIGNS FOR EXTREME SEVERE SERVICE APPLICATIONS
THE PERFECT RELIEF VALVE DESIGN FOR SEVERE SERVICE APPLICATIONS
The Kinzbach's self contained mechanical design eliminates the need for outside pressure sources/actuators for operation.
The Kinzbach's unique
'Full Open Relief' design keeps the valve fully open until the reset pressure is reached.
NO THROTTLING, which quickly damages conventional relief
Kinzbach valves are designed
to automatically reset which eliminates the safety hazard of personnel having to manually compress a spring load.
The Kinzbach Model 113 and 213 have working pressures up to 15,000 psi. The Model 313 is maximum rated at 10,000 psi.
Model 113, 213 and 313 valves offer bolt on end connections for both inlet and outlet. This provides the option to change end connections for different applications.
For reliable service in severe erosion applications, valves can be fitted with a tungsten carbide positive orifice that is a slightly smaller diameter than the seat, which moves the erosion point from the seat to the positive orifice on the downstream end.
The Kinzbach Pressure Relief Valve is designed for service in both low and high pressure pumping applications, as well as gas service in wellhead casing annulus relief applications. Each Kinzbach valve model provides a relief pressure range that can be set between 150 psi to its full working pressure, up to 15,000 psi.
Its totally unique design makes the Kinzbach Valve the only valve that will fully open when operating pressure exceeds the valve's relief set pressure and will remain fully open until the pump pressure falls below 65% of the relief valve's pressure setting, at which time the valve automatically resets itself.
The valve's elastomer/metal seat design produces "bubble tight" closures that can be repeated hundreds of times without repair.
Models 113 and 313 have a pressure
adjustment nut located inside the sprint nut
cap. This allows for an adjustable pressure
range within each spring
combination to fine
tune the valves'
With 2" Fig. 1502 Male x Female Connection
Model 213 does not have a pressure adjustment
nut, but by changing spring combinations, seat
diameter, piston diameter, and bushing diameter,
the valves relief pressure can
be set within 50 psi of
Model 213 10M C.W.P.
With 1-13/16" API 10M RTJ Flanged End Connection
Piper's Kinzbach Model 112
SAFETY RELIEF VALVES FOR FLUID APPLICATIONS
Piper's Kinzbach Model 112 Safety Relief Valve was designed for
use in high-pressure well-servicing operations such as
cementing, acidizing and fracturing, that demand accurate
pressure relief valves. With pressure settings up to 15,000 psi
(1050 bar), the model 112 enhances the safety of your personnel,
pumping equipment, well tubing, casing and complete operations.
