RP Series Three-Way

Solenoid Air Valve

APPLICATION

RP three-way valves are for use in applications where the

operation of a pneumatically operated device is

dependent upon an electrical circuit. The valve directs

supply air to the pneumatic device when the coil is

energized or de-energized, depending on the supply and

exhaust air connections.

Do not install where the ambient temperature for the

alternating current models exceeds 140ºF (60ºC) or for

the direct current models exceeds 104ºF (40ºC). The

maximum pressure should not exceed 30 psig (207 kPa).

All Series RP air valves are designed for use only as

operating devices. Where system closure, improper flow, or

loss of pressure due to valve failure can result in personal

injury and/or loss of property, it is recommended that

additional devices be added to indicate proper system

operation, (for example, blade position indication on the

damper blades in smoke damper applications).

Fig. 1. Application diagram.

OPERATION

In a typical application, supply air is connected to the

normally closed port and the control device is connected

to the common port. When the solenoid is energized, a

magnetic field activates a plunger-type valve stem and

supply air is directed to the control device. When the

solenoid is de-energized, the supply air connection is

closed and the normally open port exhausts air from the

control device. Reverse action may be obtained by

connecting the supply air to the normally open port, using

the normally closed port for exhaust. (See Fig. 1.)

INSTALLATION

IMPORTANT:

Contaminants, including water, in the air supply

may affect valve operation. It is recommended that

a filtering device be added at the air supply or

within the pneumatic system to avoid damage to

system components.

RP SERIES THREE-WAY SOLENOID AIR VALVE This air valve may be mounted in any position. It can be supported by the piping, when used, or conduit to which it is attached. When tubing is used, the bracket supplied on the valve may be used for adequate support. Tubing connections are made to the barbed connectors. Check the voltage shown on the valve data plate against the voltage of the power source to see that the right unit is being installed. WIRING SPECIFICATIONS Table 1. Models.
