100 Series 4 way Valves 3 to 175 tons 1/2" thru 3-1/8" Line Sizes

 

This series valve is available as a pressure differential pilot actuated valve as

well as an Actuator driven valve

 

In the heating cycle the discharge gas is routed through the inside coil making it the condenser and the outside coil the evaporator. In the coiling cycle the discharge gas is routed through the outside coil making it the condenser and the inside coil the evaporator. This diagram is a typical heat pump configuration.

300 Series 4 way Valves 3 to 175 tons 1/2" thru 3-1/8" Line Sizes

 

This series valve is available as a pressure differential pilot actuated valve as

well as an Actuator driven valve

 

These valves may be used in the system to direct flow. In the NORMAL POSITION the discharge gas is routed through the main condenser. In the ENERGIZED POSITION the discharged gas is routed through the auxiliary condenser and the return routed to the main condenser. No check valve is needed. This diagram is a typical heat reclaim configuration.

400 Series 3 way Valves 3 to 175 tons 1/2" thru 3-1/8" Line Sizes

 

This series valve is available as a pressure differential pilot actuated valve as

well as an Actuator driven valve

 

These valves may be used in the system to direct flow. In the de-energized position the discharge gas is routed through the main condenser. In the energized position, the discharged gas is routed through the auxiliary condenser. This diagram is a typical heat reclaim configuration.

500 Series 4 way Valves 3 to 175 tons 1/2" thru 3-1/8" Line Sizes

 

This series valve is available as a pressure differential pilot actuated valve as

well as an Actuator driven valve

 

Eliminates the need for additional solenoid valves. This valve may be used in a system with parallel condensers. The discharge is routed to one condenser or the other while the condenser not in use is pumped out to suction. This diagram is a typical heat reclaim configuration.

700 Series 3-4 way Valves 3 to 175 tons 1/2" thru 3-1/8" Line Sizes

 

This series valve is available as a pressure differential pilot actuated valve as

well as an Actuator driven valve

 

Eliminates the need for additional solenoid valves. (4 way) In the de-energized position, the discharge gas is routed through the main condenser and the auxiliary condenser is pumped out to suction. (3 way) In the energized position, discharge gas is fed through the valve and into the auxiliary condenser. The pump out line is automatically closed. This diagram is a typical heat reclaim configuration.

1700 Series 4 way Valves 6.1 to 175 tons 7/8" thru 3-1/8" Line Sizes

 

This series valve is available as a pressure differential pilot actuated valve as

well as an Actuator driven valve

 

In the NORMAL POSITION, discharge is routed to the main condenser and the auxiliary is pumped out. No solenoid valve is needed. In the ENERGIZED POSITION, discharge is routed to the auxiliary condenser and the return routed to the main condenser. No check valve is needed. The pump out is closed. This diagram is a typical heat reclaim configuration.

1300 Series 3 way Valves 3 to 175 tons 1/2" thru 3-1/8" Line Sizes

 

This series valve is available as a pressure differential pilot actuated valve as

well as an Actuator driven valve

 

In the NORMAL POSITION the C and NC ports are open through the valve and the NC port is closed off inside the valve. Discharge pressure must be supplied to the 1/4" flare on the side of the valve. The 1/4" flare fitting at the pilot (below the coil) must be piped to the suction side of the compressor. In the ENERGIZED POSITION the C and NC ports are open through the valve and the NO port is closed off inside the valve. This diagram is a typical hot gas defrost configuration.

1400 Series 3 way Valves 3 to 175 tons 1/2" thru 3-1/8" Line Sizes

 

This series valve is available as a pressure differential pilot actuated valve as

well as an Actuator driven valve

 

In the NORMAL POSITION, the discharge gas goes straight through the valve causing almost no pressure drop. The Reheat/Defrost coil is closed off inside the valve. In the ENERGIZED POSITION the discharge gas turns 90 degrees through the valve going out to the Reheat/Defrost coil. The out port is closed off inside the valve. Discharge pressure is piped to the small port opposite the Reheat/Defrost port so this valve can be used to shift suction pressure. This diagram is a typical compressor unloading configuration.

1600 Series Flow Divider 6.1 to 175 tons 7/8" thru 3-1/8" Line Sizes

 

This series valve is available as a pressure differential pilot actuated valve as

well as an Actuator driven valve

 

In the normal condition, the discharge gas is routed to (A) and (B) condensers, and the pump out is closed. In the energized position, the discharge gas is routed through the (A) condenser and the (B) condenser is pumped out to suction. (Eliminates the need for an additional solenoid valve.) This diagram is a typical flow divider configuration.
