2R130-500 & 2RS130-500
Operation: This valve is a two-way, normally closed, pilot-operated diaphragm valve. As shown in the diagrams below, when the coil is de-energized (left diagram), the pilot plunger & diaphragm sit on their respective orifices. The working medium flows through a tiny “bleed orifice” & pressurizes the cavity above the diaphragm — this system pressure, along with the spring force, seals the valve. When the valve is energized the pilot plunger allows the working medium to flow through the pilot orifice. This releases the pressure above the diaphragm and causes it to lift off of the main orifice, allowing the working medium to flow fully through the valve. Since the bleed orifice is dimensionally smaller than the main orifice, the system pressure cannot rebuild on the top of the diaphragm as long as the main orifice remains open. The working medium & flow direction are indicated in purple in the diagrams.
Safety Note: Standard valves are supplied with continuous duty coils. The proper class of insulation for the service is indicated on the coil body. The coil temperature may rise significantly if energized for extended periods—this is normal. Although the coil is made of flame-retardant material, misuse of the coil could create fire hazards & generate smoke and/or a burning odor. If these conditions are encountered, the coil temperature has risen above safe levels and the power should be disconnected immediately.

To Connect the Valve Inlet & Outlet:
• Connect the inlet & outlet to the valve ports according to the flow direction arrow marked on the valve
To Install the Coil:
• Put the coils on to the armature tube of the valve. Place the lock washer & nut on to the armature tube. Hand tighten the nut, then use a wrench to tighten the nut another quarter-turn. Do not over-tighten the nut, as it may cause the armature tube to fail prematurely.
To Connect a DIN Coil:
1. Remove the Philips-head screw from the plastic DIN housing & unplug it from the DIN coil
2. From the screw opening, push the terminal block out from the plastic DIN housing.
3. Note the “1”, “2”, and ground “⏚” symbols on the underside of the DIN enclosure.
4. For DC DIN Coils, connect “1” to your Positive Lead & “2” to your Negative lead.
5. For AC DIN Coils, connect “1” to your HOT lead, “2” to your Neutral lead, & “⏚” to your ground if required.
Do not energize the coil without installing it onto the valve or connect the coil to a different voltage than specified. This will burn the coil and could create fire hazards.
