Model 2036, 2-Way, Normally Closed Solenoid Valve

3/8”, 1/2”, 3/4” & 1” Pipe Size, Pilot Operated

DESCRIPTION

Model 2036 two-way normally closed solenoid valves
have a forged brass body. The unit has a seat material
of Acrylo-Nitrile with a metal core for use to 80ºC.
The valve coil and housing is weather, water and
saline corrosion-proof according to IP65 and
NEMA4x. The unit has a power consumption of 6 watts and
a life cycle rating greater than five million cycles.

Piloted valves use the fluid pressure to assist in opening and closing the valve, allowing the valve to operate against higher pressures than a direct acting valve.

When the pilot valve is closed, the pressure builds up via a small passage from the upstream side of the valve piston/seat. The valve seat is also acted on by a spring.

When the pilot valve opens, a passage that bypasses the valve piston/seat and connects downstream of the piston/seat is opened, relieving pressure from the top of the valve piston/seat. The inlet fluid pressure lifts up the piston to open the valve.

INSTALLATION RECOMMENDATIONS
1) Place a strainer with a porosity < 100µ upstream of valve (see Clark Solutions Model 1359 Y Strainer).
2) Mount the valve in any position preferably on a horizontal pipeline with coil upright.

Q= Flow Rate, GPM (U.S.A.)
Cv= Valve Flow Coefficient
DP= Valve Pressure Drop, PSID
G= Specific Gravity of Liquid (= 1.0 for Water)
