AMANA 167631 Piston Metering Device Orifice Opening: 0.049 For R-410A 1.5 Ton Condensing Units - HVAC - Air Conditioning - Refrigeration

FLOW CHECK PISTON

AMANA 167631 Flow Check PistonThe flow check piston is located within the control head of an orifice tube operated air conditioning or heat pump system. When position "A" is selected, the flow check piston is withdrawn from the concave in the flow plate that creates an opening for refrigerant to enter up to the correct pressure as established by the orifice diameter used in conjunction with a given sized orifice tube. The end of stroke (EOS) switch which is also located within

The AMANA 250D & 310D, under the BRAVO series of condensing units; includes a pistons metering device. This piston requires a 0.049" orifice opening when servicing, and a 0.053" orifice opening when flow checking prior to shipping from factory.

This item is an orifice designed to be used in conjunction with a flow balance check valve. The orifice is an essential component of the balancing piston. In order to ensure a precise balance, you must avoid tampering with the flow rate of this component. This component is used on a variety of 1.5 ton sizes equipment manufactured by Rheem Manufacturing Company Inc.. Do not install this product into a unit you manufacture, or into any unit which has already had an installed orifice destroyed. This

The AMANA 167631 Piston Metering Device Orifice is compatible with the following units: TELEFUNKEN: APC5P1.5N *********** Amana (new Handle) 173 631 New Water Heater Parts ****** Replaces 2075195, 1840186 ***********

Amana 167631 Piston Metering Device Orifice Opening: 0.049" For R-410A 1.5 Ton Condensing Units , Suitable for R-410A air conditioning & refrigeration product lines.

The piston is made from Monel. The piston shaft is straight with 45° angle to the rod end line. The piston rod end has sealing gland and close tolerance to meet ISO Standard pipe size requirement for O-ring. Inlet and outlet check valves are integrated into the piston body and use special seals to withstand high pressure and temperature of refrigerants. The parts of the orifice not in contact with fluid are nickel plated to improve the durability and corrosion resistance. 3#E

This 0.049 Piston Orifice is used for R-410A, 1.5-ton condensing units. This part measures 13/16 inch in diameter by 3 inch length. This orifice allows gas flow into the metering coil of refrigerant compressors to maintain pressure for constant refrigeration. The Check Valve is also located on the bottom of the piston assembly and opens when a voltage is applied from the Compressor relay contactor. It prevents gas backflow from entering into
