The PSIval is a
hydraulically operated automatic valve that combines the simplicity and
reliability of a diaphragm valve with the control capabilities of a
pilot operated, self-acting regulator. The unique design of the PSIval
optimizes both flow capacity and control. The revolutionary body design
provides a streamlined flow path and incorporates the multi-functional
elliptic diaphragm in an efficient hydrodynamic design. This design
provides superior resistance to cavitation and erosion and insures
smooth flow without turbulence or noise.
At the heart of the
valve lies the unique elliptic diaphragm, which is capable of opening
and closing at 6 PSI, as well as normal operation up to 230 PSI. The
valve’s incomparable versatility offers pressure reduction over a wide
range of flows. Other valves have limitations and require special
accessories or different diaphragms to achieve optimum results.
PSIvals’s greater range of flows overcomes these restrictions, providing
immediate solutions for general water supply and irrigation.
One basic valve…one valve spring…one diaphragm…for
all applications. Provides operational
flexibility; no need for different diaphragms and springs to meet varying
pressures or flow conditions.
Consistent performance
-
Reliable trouble free valve operation; controlled, smooth and accurate
closing and opening at low flows with drip-tight sealing.
-
Extremely stable and accurate control during shut-off and regulation;
provides versatile rangeability and low flow control.
-
High
flow capacity and very low head loss resulting from the innovatively
designed body and flow path.
-
Positive drip-tight sealing is guaranteed by the elliptical diaphragm’s
design and its resilient sealing surface.
-
Easy
inline maintenance is provided by top entry design.
-
Rugged,
high quality construction meets applicable engineering standards.
-
Proven
pressure, flow and level regulation pilots, electric solenoids and control
accessories.
Valves are used in agricultural, landscape, industrial, mining and
wastewater applications.
Dependable Control
Design based on simplicity. Engineered to perform under the most demanding
conditions. Each valve assures a controlled close, which minimizes water hammer
and absorbs the pressure shock caused by system shut-off.
High Efficiency-Low Head Loss
The flow path is wide and clear of obstructions for superior hydraulic
performance and lower pressure loss.
Pressure Reduction Over A Wide Flow Range
PSIvals are capable of reducing pressures at extremely low flow rates as well
as high flow rates due to the multi-functional elliptic diaphragm. The same
diaphragm can open, close, and reduce pressures down to 6 PSI.
Protective Coating
The interior and exterior of the valve are treated with a pliable
electrostatic spray polyester coating that will not chip, is rust resistant, and
stands up to sun, salt, and other corrosive elements. The coating process
includes pre-treatment blasting, electrostatic spraying of polyester, and
oven-heated curing to bond the paint.
Easy Maintenance
The PSIval requires minimal maintenance. The valve never needs to be removed
from the line. The bonnet is easily removed revealing the diaphragm and spring
that may require upkeep.
Hydraulic Accessories
Point Source offers a complete line of multi-purpose pilots and accessories.
By combining PSIvals with precise hydraulic accessories, solutions to both
common and more complex valve requirements are readily attained. The plastic
pilot in particular, has new innovative features, not available in similar type
products, such as larger passages for quick reaction time and non-breakable
directional assembly.
All point Source PSIvals are standard 3-way control
pilots. Two-way control is also available upon special request.
Standard valves include Manual, Electric, Pressure
Reducing, Pressure Sustaining/Relief, Hydraulic Relay, and Quick Reacting
Pressure Relief.
Additional valve control features include Surge
Anticipating-Quick Relief, Pump Control, Two Stage Opening, Float Control, and
Check Valve options.
