FLOW PATTERNS & PRESSURES FOR SERIES 2000 VALVES
If a valve is energized for long periods, this causes a temperature rise in the
coil.
QUALITY ASSURANCE
ITT’s Chihuahua Mexico [CUU] manufacturing facility is ISO 9000: 2004
certified. This prestigious certification highlights our implemented
management system of process control, continuous improvement
and high customer focus. ITT also houses R&D and engineering teams
in Wolverhampton England, as well as a second world-class valve
manufacturing facility.
Alcon Solenoid Valves are manufactured in compliance with current ISO
standards.
Each valve is 100% pressure tested for positive shut-off and “no-leak” to
atmosphere.

MODES OF OPERATION
2/2 N/C Normally Closed

connection.

FLOW DATA
There are 2 types of valve operation – Direct Acting and Pilot Operated:
a) Direct Acting – The coil supplies all the power to open the valve and the valve will operate from zero
pressure.
b) Pilot Operated – this can either be diaphragm or piston operated. These valves have a pilot hole which is
opened/closed by the coil acting upon a plunger and diaphragm or piston used to control the main orifice.
The operation relies on the media pressure difference between the inlet and outlet and a minimum operating
pressure is required to operate these valves unless stated as zero.
Alcon solenoid valves are cataloged with respect to flow: Cv, ft3/hr or lbs/hr. Individual flow charts are illustrated in the catalog for each type of Alcon valve
describing the most common application - air, water, gas or steam.
Where Cv is defined as:
The flow of water through a valve at 60º F in US gallon/minute at a pressure drop of 1 lb/in2
2/2 N/o Normally OPEN
Solenoid
Direct Acting
The dimensions of Kv values can be transposed by means of following factors:
Cv = 1.16 x Kv
Kv = 0.853 x Cv
Solenoid Pilot
Operated
2 way, normally open, energise to close, de-energise to open, with one inlet and one outlet connection. Can be either
direct acting or pilot operated.
3/2 N/C Normally Closed
Where Kv is defined as:
1 cubic meter an hour of water with a pressure drop of 1 bar (m3/hr ∆p1 bar).
(1 m3/hr = 1000 liters per hour).
General Purpose
Valve open when energized, closed when de-energized. This valve operates on the same principle as the 2/2 N/C
version except the valve has 3 connections, 2 orifices, one permanently open, one permanently closed. The use of
Valve these are for operation of actuators for large valves where single cylinder spring return system is employed.
3/2 N/O Normally OPEN
Valve open when de-energized, closed when energized

a) Single Solenoid – 2 position, spool and sleeve type, which is based on an air pilot return mechanism. When
de-energized, the valve allows one inlet and one outlet to be connected, exhausting the other inlet/outlet
connection through an exhaust port. On energization, the action reverses.
b) Dual Solenoid Valves – these spool and sleeve type solenoid valves are momentary contact type. When
one coil is energized, one inlet is connected to one outlet, with the other inlet/outlet connection connected
to an exhaust port, when the coil is de-energized and other coil energized, the action is reversed. These
valves are for use on double acting cylinder applications.
