Parker1335BA3INAT2-Way Normally Closed Solenoid Valve, 3/8 in NPT, Brass Body, 14 mm Orifice, Cv 2.75

Product Description

What this part is

Jefferson 1335BA3INAT two-way solenoid valve from the 1335 general purpose series. A two-way solenoid valve has one inlet and one outlet: energising the coil lifts the armature off the seat and opens the flow path, de-energising drops it back. Manufacturer: Jefferson. Part Number: 1335BA3-INAT. Series: 1335, general purpose. Ways and Positions: 2-way, 2-position. Operation: normally closed. Port Size: 3/8 in NPT. Body Material: brass. Seat Material: Buna-N. Orifice: 14 mm (0.55 in). Flow Coefficient: Cv 2.75. Pressure Range: 0 to 105 psig. Maximum Fluid Temperature: 176 °F (80 °C). Weight: 1.75 lb.

Decoding the designation

1335 — Jefferson’s 1335 general purpose two-way solenoid valve series.

B — brass body.

A3 — the 3/8 in NPT port size within the series.

1335BA3-INAT — the punctuated form; 1335BA3INAT is the same part number run together.

What these specs mean in practice

Operation: normally closed. The valve seals with the coil de-energised, so a power failure shuts the line. That is the fail-safe direction for a fuel, water or air supply. Pressure Range: 0 to 105 psig. The lower limit of zero means the valve does not need a minimum differential to open, so it works on gravity-fed and low-head lines as well as on pressurised ones. Flow Coefficient: Cv 2.75 with a 14 mm orifice. That is a large orifice for a 3/8 in body, which keeps the pressure drop across the valve low at working flow. Body Material: brass. Seat Material: Buna-N. Brass and Buna-N are the standard combination for water, air, light oil and inert gas service. Maximum Fluid Temperature: 176 °F (80 °C).

Mounting data

Port Size: 3/8 in NPT, inlet and outlet. Body Material: brass. Weight: 1.75 lb. The 1335 series is a threaded in-line valve, so it drops into a 3/8 in NPT pipe run without a subbase or manifold.

Quantity and configuration

Unit Quantity: 1 Pc. One complete valve with coil per listing.

Interchange guidance

1335BA3INAT, 1335BA3-INAT and 1335 BA3 INAT are the same part number. The 1335 series shares one brass body and one seat across its variants, and the trailing letters after 1335BA3 carry the coil and enclosure execution; siblings catalogued as 1335BA3T, 1335BA3AT and 1335BA3DT share this valve’s 3/8 in NPT porting, 14 mm orifice, Cv 2.75 and 0 to 105 psig range.
