Packaging & Delivery

1. Production Overview

The 13X1-2 series is a family of diaphragm solenoid valve with manifold, and its mainly

function is to switch on and switch off the liquid. These series have multiple option types, which

can be customized with different number of ports and they are suitable for different reagents in

different condition. It’s a high precision, low cost and maintenance-free solenoid valve and its life

cycle is more than 2 million.

1.1.Characteristics Of 13X1-2 Series

Customized: solenoid valve manifold can be customized with different number of ports,

arrangement method and mounting ports according to customers’ requirement.

Small dead volume: no dead volume inside the solenoid valve body

Multiples option for wetted material:

1. Body material:PTFE, POM

2. Seal material:EPDM, FFKM

Long lifetime, good performance.

1.2.Words Definition

The coefficient of variation (CV)

It is remarked as CV, but in China we mark it as KV. They are both non-dimensional

parameters and replaceable. CV means the liquid flow capability of elements. In actual design and

use, it must calculate to a flow dimensional parameter as application condition.

——The actual flow of medium, unit: gal/min;

——The density of water under 60°F.

——A constant differential pressure of element,

——The actual pressure drop of the tested element between inlet and outlet.

When it replaced as common physical dimension parameter in China, then:

Cv=0.03, means under the condition of 25℃, 50KPa, the flow of component is 5.1ml/s.

Response Time (T)

Input air/water at 0.25MPa and maximum working pressure drop from inlet port, input rated

control electrical signal to make the tested solenoid valve open and close, then we’ll get the

change of outlet pressure which we can measure from pressure sensor. At the same time, we’ll

get the lapse of time which starts from power on/off to rise to 90% of max pressure (normally closed valve) and drop to 10% of max pressure (normally open valve) by quick response time

measure devise. Repeatedly test several times and take the average valve as the power on

response time and the power off response time.

As engineering experience, it is the design critical value that response time above 50ms. The

aspiration of valve may not stable. Therefore, the response time is not beyond 50ms within

nominal lifetime.

In addition, there is a response time at current method in this industry. The change of circuit

leads to current change, according to the action of solenoid valve. The response time T1, T2 at

current method is normally less than the response time(T) which measured by air flow method.

Seal Capability

Pressure strengthen (outside leakage)

Solenoid valve powers on, the outlet is close, and the inlet water under condition of 5℃~40℃

and nominal pressure is 1.5 times. Then ensure all connector won’t leak within 1min.

Sealing (inside leakage)

For two normally closed branches, give one port pressures; put the other port into water.

Under the nominal pressure, there is no bubble come out in 1min.
