Bi-Flow Distributors
Bi-Flow Distributors
We offer two basic styles of “piston type” flow metering devices, (“Bi-Flow Distributors”) as shown.
A popular method of eliminating costly “expansion valves,” difficult to control “Capillary Tubing” and sometimes leaky check valves, this device contains a precision-machined “Orifice Piston.” This piston strictly regulates flow in one direction, while allowing relatively open flow in the opposite direction.
When two of these units are installed back to back between the condenser and evaporator, with the proper size pistons, they provide performance and control in a heat pump unit.
We offer a wide range of variations of this product. The connections may be produced in any size and configuration you may require. The circuit tubing may also be provided in the size, shape, and quantity you need to fit your application.
These units may also be purchased at any stage of completion. We can provide a unit complete with piston, torqued to specification and ready to install into your unit, or you may purchase any of these components separately.
Shown above are two examples of our most popular Bi-Flow Distributors. A full assembly consists of a distributor body, distributor tubes, an orifice piston, a nut, a Teflon gasket and an end piece. As a full assembly, the nut is torqued to 20 ft/lbs and is ready to install into your unit. These distributors can be manufactured with copper tubing of various O.D.’s and lengths. The copper tubing can be expanded on the ends to fit your connection dimensions. Custom designs are welcomed.
Below is the nomenclature to assist you in selecting the Spinco part number that suits your application. Contact our sales department at 315-331-6285 and our representatives will gladly assist you.
- To order the above assembly, less the orifice piston, simply drop the -055.
- (The unit will be shipped un-assembled unless it is requested to be assembled).
- To omit any other part of the unit, simply replace the appropriate digit(s) with zero(s)
- Ex: 7204000 is a Bi-Flow distributor body ONLY, with four circuit holes, for 1/8″ tubing.
To order this same distributor with 12″ long circuit tubes installed, the part number is; 72041200.
- Nut Only = 75-01
- Gasket Only = P900033-1
- End Piece Only = 75EPXX
- 75EP001 = 3/8″ Tube, 2 5/8″ long, one end expanded to 3/8″ I.D.
- 75EP002 = 3/8″ Straight Tube, 1 1/8″ long
- 75EP003 = 1/2″ Straight Tube, 1 13/16″ long
- 75EP004 = 1/2″ Tube, 2 1/2″ long, one end expanded to 1/2″ I.D.
- 75EP005 = 3/8″ Tube, 1 1/8″ long, one end expanded to 3/8″ I.D.
Orifice Pistons and Piston Kits
Piston kits are provided so that the customer may change the piston in the field, in order to optimize the unit. The piston is sealed in a plastic bag, with complete directions on how to extract the existing piston and install the new one. Also included are a wire hook to remove the existing piston, a new gasket and a label to identify the size piston inside the unit once it is sealed back up. The pistons come in two basic body styles and can be provided with either Teflon or neoprene seals.
“Fluted” Piston with Teflon Seal
“Fluted” Piston – Style 7PK5XXX
“Fluted” Piston – Style 3PKXXX
Orifice Pistons
Pistons may also be purchased separately, (as may all other components of a Bi-Flow Distributor Assembly). When shipped separately, they are packaged in plastic protective tubes as shown below. No special instructions are needed. Simply order the size orifice piston you require.
Brass Refrigerant Distributor
Refrigerant Distributors
Refrigerant distributors consist of two basic designs, the “Orifice Type” and the “Low Pressure Type”. Spinco Metal Products manufactures both types in a wide range of variations. The “Orifice Type” may have a permanent or a replaceable nozzle, depending on the body style selected. The nozzle mixes the two-phase fluid and regulates the flow of fluid through the orifice, into the circuit passages and on to the coil. Various nozzles can be selected for the proper loads required as determined by the chart below. This allows the use of one body type for several applications.
The “Low Pressure Type” has a radius on the inlet of the “throat.” The fluid flows through the radius and throat, into diverging circuit holes and on to the coil. The radius versus the flat orifice face results in the lower pressure drop across this style distributor. The throat diameter is sized according to the number and size of circuits required and cannot be altered in the field.
Nozzles and retainer rings can be purchased separately. The sizes of the orifice and nozzle body are required. Use the chart below to reference the necessary information. Optional threaded holes are available upon request.
Tapped holes available upon request. These holes do not alter the function of the nozzle and are seldom used.
Nozzle – Type Distributors
Nozzle – Type Distributors With Flare
Heat Pump and Hot Gas Defrost Distributors
When ordering Heat Pump and Hot Gas Distributors, specify number and size of side connections
Flare – Type Low Pressure Drop Distributors
To order distributors without a flare tube or nut use “0F”, (zero F), as shown. The neck diameter will be supplied to fit inside an unexpanded tube.
Venturi Style Distributors
Male Swivel Nut Tube-O-Type
Female Fitting Tube-O-Type
Male Inverted Swivel Nut Tube-O-Type
Male Inverted Swivel Nut Tube-O-Type
Variations of Length & Tube Connections Available
