Three way valves have three pipe
connections and two orifices. When one orifice is open, the other is closed,
and vice versa. They are commonly used to alternately apply pressure to and
exhaust pressure from a valve actuator or a single-acting cylinder.
Three Types of Operations Apply:
Normally Closed (NC)
When the valve is
de-energized, the pressure port is closed and the exhaust port is
connected to the cylinder poert. When the valve is energized, the exhaust
port is closed and the pressure port is connected to the cylinder port.
Normally Open (NO)
When the valve is de-energized, the pressure port is connected to the
cylinder port and the exhaust port is closed. When the vlave is energized,
the pressure port is closed and the cylinder port is connected to the
exhaust port.
Universal (Univ)
This allows the vlave to be connected in either the Normally Closed or
Normally Open position ... or to select one of two fluids or to divert
flow from one port to another.
Standard Optional Features:
Solenoid valves are supplied, as listed, with either
Red-Hat II molded epoxy solenoids or Red-Hat solenoids with metal
enclosures. Red-Hat II valves are identified by the letter "G"
or "H" in their catalog numbers e.g., 8320G1. 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.
