Model 1342, 2-Way, NC or NO Solenoid Valve


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

DESCRIPTION
Model 1342 two-way normally closed and normally open solenoid valves are available in brass, 304 or 316 stainless steel bodies. A variety of seal and seat materials including Acrylo-Nitrile, Neoprene®, Ethylpropylene, Viton®, and Teflon® satisfy many general industry applications.

The valves employ a solenoid operated pilot valve to change valve state. This enables the valve to use the pressure at the inlet of the valve to assist in changing the valve’s state, resulting in a higher operating pressure rating.

Options include weather proof housing, energized coil indicator light and manual override on main passage and on pilot orifice.

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
Place a strainer with a porosity < 100µ upstream of valve (see Clark Solutions Model 1359 Y Strainer).
The valve input pressure must always be greater than the valve outlet pressure.
In order for the N.C. or N.O. valve to open, the minimum pressures per specs must be maintained.
