1011 Threaded Types High temperature High pressure usage for Environmental COD water quality monitoring analyzer solenoid valve

Product Overview

Description

1 Product Overview

1011-2 series solenoid valve is a series of diaphragm solenoid valve with 1.5mm orifice  developed by Keyto independently. Its mainly function is switching on/off liquid path, to resist weak acid and bases, high temperature and high pressure resistance. The wetted material has multiple option types, depends on different reagents under different working condition. The life cycle can reach more than 2 million cycles. It’s a high precision, low cost and maintenance-free diaphragm solenoid valve.

1.1 Characteristics Of 1011-32-PFU/5N

Long lifetime, high performance, strong acid and base corrosion resistance, high temperature and high pressure resistance.

 

1.2 Words Definition    

The coefficient of variation Cv

It is remarked as Cv, while in China we mark it as KV. They are both non-dimensional parameters and convertible. Cv means the liquid flow capability of element. In practical design and usage, it has to be converted to a dimensional flow reference based on application conditions.

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

——The density of water under 60°F;

——A constant differential pressure of elements;

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

Converted to the domestic general dimension, then:

Cv=0.03,means under the condition of 25℃, 50KPa, the flow of element is 5.0mL/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, 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 value 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 pressure; put the other port into water. Under the nominal pressure, there is no bubbles come out in 1min.
