Choosing the Right Valve

1
Choosing the
Right Valve
2

• There are two basic kinds of solenoid valves
  2-way and 3-way valves.
• Valves can be designed as normally-open or
  normally-closed.
• Valves can be designed to accommodate short or
  long cycle times.

Choosing the

• The most common voltages are 24 VAC, 120 VAC, 240
  VAC, 6 VDC, 12 VDC, and 24 VDC, but Solenoid
  Solutions can accommodate other voltage
  requirements.
• Consider whether the valve needs to operate on
  battery power.

Right Voltage
For The Valve
There are three factors to consider when
designing a solenoid valve to conserve energy
Does the
Valve Need to

• Coil selection
• Bump and hold circuitry
• Latching options

Choosing the
Right Valve
For The Medium

• Will the valve operate in gas or liquid?
• Different seal materials are used for different
  media.
• Different mediums have different specific gravity
  and viscosity, which can affect the flow rate and
  need to be considered when choosing valves.

What
consider
Flow Rate
Pressure Will the Valve
Need to operate in?

• Flow rate is determined by the pressure and the
  size of the orifice.
• Also consider the specific gravity of the medium,
  the viscosity of the medium, and the temperature
  of operations.

• What is the normal range and maximum amount of
  pressure that the valve will operate under?

6
Determining the
Proper Coil Type

• The larger the size of the orifice and the
  greater the pressure, the more power it requires
  to open the valve against the pressure of the
  flow.
• The greater the power requirements for the valve,
  the greater the wattage required in the coil.
• Solenoid Solutions offers a variety of coils in
  molded or tape-wrapped designs.
• Coil designs for electrical connections include
• Coils with wire leads
• Coils with spade connections
• Coils with DIN connections
• Coils with conduit electrical connections

7
Determining

• Ports are where the plumbing connections attach
  to the solenoid valve.
• Large valves containing large port sizes are
  generally more expensive than smaller valves.
• Remember, port size does not determine the rate
  of flow. Flow rate depends on pressure and the
  orifice size.
• Solenoid Solutions offers a variety of types and
  sizes of connections.

Conditions in the
Operating Environment
To consider

• These operating conditions factor into what valve
  is best suited for your application
• High temperatures
• Corrosive substances
• High vibration levels
• Limited energy available
• Limited space available
• Any agency approvals required

• Sometimes, a system requires more than one
  solenoid valve.
• Are there multiple controls, fittings or sensors
  associated with the valve?
• In some cases, a manifold may be best suited to
  the application.
• Manifolds might be more cost-effective and
  space-efficient in some systems.

One valve Needed?
10
Need Valve Assembly?

• Do you need sub-assembly assistance?
• Solenoid Solutions can manufacture your valves,
  and then ship with properly torqued components.
• We can clock the fittings at precise angles for
  you.
• We can prepare the electrical leads for you.

Summary
Choosing the right solenoid valve includes
considering voltage requirements, what media will
flow through the valve, the amount of pressure,
what the flow rate should be, what type of coil
is needed, and the environmental conditions.
