Valve Controls
The 4” (10.2 cm.) valve size accepts the same set
of valve controls described below:
Electronic Solenoid Valve
The optional Electronic Solenoid Valve, which
must be ordered separately, opens upon electric
energy being applied – thus relieving the pressure
above the valve piston and causing the cylinder
valve to open. For electrical connections, the
Electronic Solenoid Valve is furnished with 24"
(61 cm.) pigtails.
Local Manual Control Head
The Local Manual Control Head (Model CPY-
LMC2) is installed on the Supervised Electronic
Releasing Solenoid, Model CPYEC-2-24. When
the safety pull pin is taken out, and the push
button is manually triggered, it will cause a pin to
depress and open the pilot check on the valve.
Agent pressure is then released above the valve
piston.
Piston Actuator / Secondary Cylinder
The Piston Actuator / Secondary Cylinder (Model
CPY-PAS2) installs on the top-plug adapter.
Model CPY-PAS2 contains a piston of sufficient
area to provide the necessary force to open the
pilot check – once pressure from the agent
discharge of a primary cylinder is applied
through 1/4" (0.64 cm.) tubing. Additionally,
Model CPY-PAS2 is used on piston-operated
secondary cylinders, which are released
simultaneously with the primary Sinorix
cylinder.
One (1) primary cylinder can be used to pressure
operate up to a maximum of seven (7)
secondary cylinders. If more than seven (7)
cylinders are required, the engineer may use two
(2) electric primary Sinorix cylinders.
All cylinder valves have a pressure-actuation
outlet port. The piston-actuation outlet port
opens into the same space as the valve outlet
and is only under pressure while the valve is
discharging. The port has a 1/8" (0.32 cm.) pipe
thread, which is fitted with a pipe plug.
The pipe plug is removed when the port is used.
The tubing or pipe is connected to the outlet
`M,’ and runs to the pressure actuators on the
secondary cylinders.
