Product Description

Solenoid pinch valves

Product Description

1.Principle of electromagnetic pinch valve

The electromagnetic pinch valve (referred to as the pinch valve for short) is driven by an electromagnetic solenoid and controls opening and closing by squeezing or loosening the hose. The medium only passes through the hose, the other parts in the valve body will not come into contact with the chemically corrosive medium, just replace the hose, which means that the pinch valve is more economical compared to other types of solenoid valves. No cross contamination.

2.Scope of use:

It is suitable for chemical, medical, and environmental protection industries, and is mainly used in water quality, urine, biochemistry, blood cell analysis, and waste liquid discharge.

3.Strong points of this kind of pinch valve:

1.) For voltage range,the allowable fluctuation range is ±7%.
2.) Higher pressure bearing, especially fluorine rubber hose, can be applied to most fluid fields.
3.) The valve head is installed with a limited position device, and the tube will not break or stick when used for a long time.
4.) Special matching hose to ensure the best rebound life.
5.) Product performance and quality are stable and reliable.
4.Hose model and its installation and use

·When using, pay attention that the pipe must be put into the valve body to ensure the stability of the valve
·Silicone tube (the inner wall of the tube is very smooth, excellent memory, the tube will not stick in the closed state for a long time).
·Biochemical tubes (acid and alkali resistant, but used in oily or organic solvents). The hose installation groove on the valve body has a smooth arc structure, and the user can conveniently install and remove the hose.

Hose installation:

The gap of the groove is slightly smaller than the outer diameter of the hose, but the cross-sectional area of the pipe is ensured to be equal, and the hose is also tightly fixed.

5.Service life and advantages
·The service life of pinch valve is over 1 million times.
·Limited position device when using silicone tube. The limit device prevents the pipe from being clipped or stuck.
·The pinch valve can work continuously under full load for a long time,without any damage.
·The precise stroke and effective tightening force set in the design ,which protect the hose and greatly extend the life of the pinch valve.
·The valve body is made of PBT/PC alloy and the valve stem is made of stainless steel, which has good temperature resistance and chemical resistance.
· In addition, the optimized design of pinch valve mechanism makes the working efficiency more efficient and can be directly connected with other equipment.No other electronic device driver is required.
