Series WCM

Tough, Rugged 1/2" Engineered Thermoplastic Solenoid Valve
for Water and Mild Solutions
2,000,000+ Cycle Life!

wetted core solenoid valve offers the ultimate design quality in its price range

125 PSI inlet & backpressure rating with 0.4 Cv
Continuous duty, NEMA 4X CSA approved coil
Rugged black polypropylene design, normally-closed

Designed for applications requiring a compact, very cost effective and high pressure rated valve with extended cycle life. This valve is ideal if your process uses less aggressive liquids that are compatible with a wetted metal core. Among lower cost solenoid valves, Series WCM represents the best combination of price and performance available.

Features:

Compact Size: At just over 4 in. high, these valves are ideal for limited space installations. Weighs just 13 oz. total.
Economical: Low unit cost coupled with high pressure ratings and considerable flow rate (Cv of 0.4) offer excellent opportunities for systems requiring quick opening/quick closing solenoid valves.
High Pressure: Particularly for applications where high back-pressures (up to 125 PSI) are required e.g. controlling flow to spray nozzles, high pressure water injections, etc. Inlet pressure to 125 PSI. Series WCM will open or close under any combination of pressures, as long as backpressure does not significantly exceed inlet pressure.
(Please contact our Technical Group at 973-256-3000 if you have questions about your specific application).

Unique Design: Glass-filled polypropylene cover isolates coil and protects valve body from excessive heat, permitting up to 60 cycles per minute.
Versatility: The wetted metal core is well suited to city water, many wastewater applications, pure water, and mild chemicals.
Superior Performance: 2,000,000 cycle design.
Energy Efficient: Molded 11 Watt NEMA 4X style coil with DIN standard connector results in low energy consumption...CSA approved.
Size: 1/2 in. pipe size with .14" (3.05 mm) Orifice.
Corrosion Resistant: Rugged thermoplastic construction is resistant to harsh environments.

Series WCM - 1/2" Normally-Closed Wetted Core Solenoid Valve for water and mild solutions

Design and Operation:

Note in the dimensional drawing above that process liquid is in contact with metal parts in Series WCM. All other Plast-O-Matic Solenoid Valves have a "shielded core," in which no metals are in contact with process liquid. Suitability of Series WCM for a particular application is determined by corrosion/purity parameters of the process liquid. In many cases a physical test of the valve under operating conditions is the only way to ensure the success of a particular valve for a specific application. The ultimate determination of suitability of any product or material is the sole responsibility of the user.

½"	.14 3.05	11	0.4	125 8.3	125 8.3	WCM4EP6W11-PP
No minimum operating differential pressure required to open or close; valve will begin to open if outlet pressure significantly exceeds inlet pressure.

Notes:

The Model Number listed shows EPDM seals. For Viton seals (optional) change 'EP' to 'V'; WCM4V6W11-PP. Price is the same.

Model Numbers shown with 'W11' (water and dust tight NEMA 4 style coil).

Valves are rated for full vacuum of 30 in. of mercury (Hg).

Black polypro is standard body material.
