Red-Hat II

2, 3, and 4 way Solenoid Valves

ASCO Red Hat II solenoid valves are available in a multitude of styles, port sizes, pressure & temperature ratings, and coil options. Below are brief descriptions of the main valve groups available.

ASCO 2 way Valves

The 2 way solenoid operated and air operated valves have one inlet and one outlet connection. They are available with the following types of operation:

Solenoid Valves

Normally Closed -- closed when the coil is de-energized, open when energized.

Normally Open -- open when the coil is de-energized, closed when energized.

 

Air Operated Valves

Normally Closed -- closed when the operator is exhausted, open when pressurized.

Normally Open -- open when the coil is exhausted, closed when pressurized.

Solenoid operated valves are available, as listed, with Red Hat solenoids having metal enclosures, or with Red Hat II molded epoxy solenoids. Red Hat II solenoid valves are identified by the change letter "G" in their catalog numbers, e.g. 8030G16, and are shown in red.

Air operated valves are available, as listed, with either instrument air operators (3-30 psig) or pneumatic operators (30-125 psig).

ASCO 3 way Valves

The 3 way solenoid operated and air operated valves have three pipe connections and two orifices; either orifice is open when the other is closed. The valves are available with the following types of operation:

Solenoid Valves

Normally Closed -- exhausts pressure when the coil is de-energized, applies pressure when energized.

Normally Open -- applies pressure when the coil is de-energized, exhausts pressure when energized.

Universal -- for normally closed or normally open operation (8317 Series), or pressure at any port (8300, 8314, 8320, 8325 and 8380 Series).

Air Operated Valves

Normally Closed -- exhausts pressure when the operator is exhausted, applies pressure when pressurized.

Normally Open -- applies pressure when the coil is exhausted, exhausts pressure when pressurized.

Universal -- for normally closed or normally open operation.

 

ASCO 4 way Valves

The 4 way solenoid operated and air operated valves are available as shown in either 4-ported or 5-ported configuration. They are available with the following types of operation:

Single Solenoid Valves

Valve shifts when solenoid is energized, returns to normal position when de-energized.

 

Dual Solenoid Valves

Valve shifts when one solenoid is energized, returns when the other is energized. May be energized momentarily or continuously.

Single Air Operator Valves

Valve shifts when operator is pressurized, returns when energized,

Solenoid operated valves are available, as listed, with Red Hat solenoids having metal enclosures, or with Red Hat II molded epoxy solenoids. Red Hat II solenoid valves are identified by the change letter "G" in their catalog numbers, e.g. 8030G16, and are shown in red.

Air operated valves are available, as listed, with either instrument air operators (3-30 psig) or pneumatic operators (30-125 psig).

Many optional features may be added to your valves, e.g., high temperature Class H molded coils, manual operators and metering devices. See the Optional Features Section for details.
