F3 Flanged Valve General Features
The Emech valve utilizes zirconia shear action disc
technology to provide tight shut-off, high pressure
differential capability, and long life integrity.
Combined with the Emech electronic actuator, high
performance stand-alone closed loop temperature
control is possible.
The extremely hard nature of zirconia produces
outstanding resistance to wear and cavitation damage
compared with conventional elastomer and plastic seated
valves, minimizing seal replacement requirements and
plant down time.
Valve Features
Features of the Emech G1 Actuated Digital Mixer
• Analog (4-20mA input and output ports)
Electrical stepper motor control
Speed, position, and acceleration control
User defined ‘2-speed’ stroke can eliminate water hammer
Precise positioning achieving 0.03° valve seat placement
Local closed loop control of temperature
External RS232 connection (cable supplied) communication for special
mode configuration.
Local/remote control options
Two operating modes: Stand-alone control via onboard keypad or
remote control via external 4-20mA
Failsafe position feedback (non-contact absolute encoder)
Keypad: 4 membrane switches with ‘dual touch’ safety features
Display: 3.5 digit LCD display with back light
Push button power switch providing soft start
electronic control
ee CPAC0002 IOM for details about the Emech G1 Digital Actuator)
Emech Electronic Mixing Control
The Emech F3 3-port flange valve can be fitted with the
Emech G1 electronic actuator, and Emech temperature
probe. The calibrated temperature probe (NTC) fits the
tapping in the outlet port, and connects via cable for the G1
actuator. With this temperature feedback signal, the G1
actuator provides temperature control accuracy
+/-0.9°F (0.5°C) over 32°-212°F (0°-100°C) control range.
Even with sudden changes of inlet pressure and
temperature to the valve, the G1 actuator aggressively
minimizes outlet temperature variations. Contact
Armstrong for this and other mix control options.

F3 Break Open Torques
Break Open Torque
F3 Break Open Torque
Closed Pressure (psi)
Note:
1.
The charted seating and unseating torques are the sum of all friction and resistance for
opening and closing of the disc against the indicated pressure differential for normal
service
2.
The relationship between values are linear, and can therefore be interpolated between nominated values.
3.
The effect of dynamic torque is not considered in the table.
4.
In sizing operators it is not necessary to include safety factors.
5.
Break-open torques are approximately equal to the shut-off torques.
The charted values are based on clean liquid service at temperatures between 32°F to 212°F (0°C to
100°C) with no internal deposition or chemical attack, operated a minimum of once a day.
*
For conditions that vary from those noted above, apply the following application factors.
Note: The above factors are cumulative but never more than 2 x the value shown in the Break Open Torque tables above.
