Press to specification solenoid valve assembly

1 . A method of assembling a valve, the method comprising:

inserting a stem of a plunger into a body of the valve from a first end of the body;

inserting a poppet into the body from a second end of the body, the second end of the body being longitudinally opposite the first end of the body;

initiating a first fluid flow between a first port of the body and a second port of the body, and through a first valve seat of the body;

monitoring the first fluid flow;

pressing the poppet towards the first end of the body and onto the stem of the plunger until the poppet reaches a first position where the first fluid flow stops; and

attaching the poppet to the plunger at the first position where the first fluid flow stops.

2 . The method of claim 1 , wherein attaching the poppet to the plunger includes coupling an exterior surface of the plunger with an interior surface of the poppet via press-fit.

3 . The method of claim 1 , further comprising

inserting a cap having a second valve seat into the body from the second end of the body;

initiating a second fluid flow between the first port of the body and a third port of the body, and through the cap;

monitoring the second fluid flow;

energizing a coil of the valve;

pressing the cap towards the first end of the body and into the body of the valve until the cap reaches a second position where the poppet engages the second valve seat and the second fluid flow stops; and

attaching the cap to the body at the second position where the poppet engages the second valve seat and the second fluid flow stops.

4 . The method of claim 3 , wherein attaching the cap to the body includes sealingly coupling an exterior surface of the cap with an interior surface of the body of the valve via press-fit.

5 . The method of claim 3 , further comprising

monitoring a power consumption of the coil; and

repeating the step of pressing the cap into the body of the valve until the power consumption matches a setpoint.

6 . The method of claim 1 , further comprising

inserting a cap having a second valve seat into the body from the second end of the body;

initiating a second fluid flow between the first port of the body and a third port of the body, and through the cap;

monitoring the second fluid flow; and

pressing, using linear pressure, the cap towards the first end of the body and into the body of the valve until cap reaches a second position where the poppet engages the second valve seat and a target rate of the second fluid flow is achieved; and

attaching the cap to the body at the second position where the poppet engages the second valve seat and the target rate of the second fluid flow is achieved.

7 . The method of claim 6 , wherein attaching the cap to the body includes sealingly coupling an exterior surface of the cap with an interior surface of the body of the valve via press-fit.

8 . The method of claim 6 , further comprising

monitoring a power consumption of the coil; and

repeating the step of pressing the cap into the body until the power consumption matches a setpoint.

9 . The method of claim 1 , further comprising

de-energizing the coil of the valve; and

monitoring for a sound caused by a plunger of the valve contacting a stop of the valve.

10 . The method of claim 9 , further comprising

repeating, until the sound caused by the plunger contacting the stop is no longer detected, the steps of

pressing the poppet towards the first end of the body and onto the stem of the plunger;

energizing the coil of the valve;

de-energizing the coil of the valve; and

monitoring for the sound caused by the plunger contacting the stop.

11 . A method of assembling a valve, the method comprising:

initiating a first fluid flow between a common port and a normally closed port of the valve;

monitoring the first fluid flow with a flow meter;

aligning a poppet with a plunger of the valve;

linearly pressing the poppet onto the plunger of the valve until the poppet engages a first valve seat and the first fluid flow stops;

initiating a second fluid flow between the common port and a normally open port of the valve;

monitoring the second fluid flow with the flow meter;

energizing a coil of the valve to disengage the poppet from the first valve seat; and

linearly pressing a cap having a second valve seat into a body of the valve until the poppet engages the second valve seat and the second fluid flow stops.

12 . The method of claim 11 , further comprising

measuring an electrical power consumption of the coil; and

repeating the step of linearly pressing the cap into the body until the electrical power consumption matches a setpoint.

13 . The method of claim 9 , further comprising

de-energizing the coil of the valve; and

monitoring for a sound caused by a plunger of the valve contacting a stop of the valve.

14 . The method of claim 13 , further comprising

repeating, until the sound caused by the plunger contacting the stop is no longer detected, the steps of

linearly pressing the poppet onto the plunger;

energizing the coil of the valve;

de-energizing the coil of the valve; and

monitoring for the sound caused by the plunger contacting the stop.

15 . The method of claim 14 , wherein the steps of claim 11 are performed before the step of pressing the cap into the body.

16 . A method of assembling a valve, the method comprising:

initiating a fluid flow between a common port and a normally open port of the valve;

energizing a coil of the valve to dispose a poppet of the valve in an energized position; and

pressing a cap having a valve seat into a body of the valve until the valve seat engages the poppet and the fluid flow stops;

wherein pressing the cap into the body of the valve includes sealingly coupling an exterior surface of the cap with an interior surface of the body of the valve via press-fit.

17 . The method of claim 16 , further including

monitoring a power consumption of the coil; and

repeating the step of pressing the cap into the body until the power consumption matches a setpoint.

18 . The method of claim 16 , further including

energizing the coil of the valve;

de-energizing the coil of the valve; and

monitoring for a sound caused by a plunger of the valve contacting a stop of the valve.

19 . The method of claim 18 , further including

repeating, until the sound caused by the plunger contacting the stop is no longer detected, the steps of

pressing a poppet onto a plunger of the valve;

energizing the coil of the valve;

de-energizing the coil of the valve; and

monitoring for the sound caused by the plunger contacting the stop.

20 . The method of claim 19 , wherein the steps of claim 19 are performed before the step of pressing the cap into the body.
