Below you can learn about our various constant
pressure valves. Please read on to find out more about pump
stop valves and feel free to contact us with any questions
you may have.
Constant pressure valves were designed mainly
to keep your pump motor from cycling on and off while your
using water. What's really neat about these valves is that
they also give you constant pressure once the pump starts
and keeps it constant while your using water.
For instance, your in the shower, the pump is running, you
have dialed the valve in for 60 psi, your shower is stinging
you with the 60 psi. At that moment, someone flushes a toilet,
the valve opens a little further, lets more water through
while maintaining the same constant 60 lbs.
These valves have a bypass of either 2.95 gpm
or 2 gpm or less. You can specify which bypass flow rate you
require for special applications. They can also be custom
ordered to fit any application. Get with us by phone or email
with your specs.
To start off, there is the PSP valve. It is
a small plastic device that goes in line between the pump
and the pressure tank/pressure switch as do all the other
valves. This valve is preset at either 40,50 or 60 psi. These
plastic preset valves can develop a leak if your water is
aggressive enough. Please be forwarned: There will be no
warranty if they leak. If you want a trouble free valve,
use the brass or stainless in the smaller valves and brass
or cast iron in the larger varieties.

If you like to tweak your own pressure, there
is the PS brass constant pressure valve. This valve is adjustable
and comes in 3/4", 1" , 1-1/4" and 2".
Next is the Popup-ADJ which comes in 1", 1-1/4"
and 2". They are all adjustable without the need for
a gauge. The adjustment is built into the valve. You pop the
cap up turn it and watch the pressure change on a numbered
wheel. The one inch valve is stainless steel and the 1-1/4"
and 2" are brass. The other great thing about this constant
pressure valve is that you never have to remove the valve
from the plumbing to make repairs. If something went wrong
with the internal workings, you simply remove the large nut
by unscrewing it and replace with a new one. It also has a
screen built in. If the screen were to plug during installation
with PVC glue or cuttings, you can easily remove the internal
workings, remove and clean the screen and screw it back together.

For the commercial aplications there are the cast iron models
that go from 1-1/4" to 4" for much higher flow rates.
