Pinch Valves

Pinch Valve is made up of two parts: the upper side is the body, and the lower
side is the connection that can hold the pipe. Keyto pinch valve has three
series. The mainly different is the port size. The port size means the pipe
diameter you want to use.

In addition to port size, we have many functions to choose from. like single
port or dual port, and different installations and different voltages to meet
your unique needs.

Types of Pinch Valves
Pinch Valve 1213
Double Channel Pinch Valve, the medium only resists in the tube and little
cross contamination, tube size recommend: 1.5mm*3mm/1.6mm*3.2mm.

Pinch Valve 1224
Single Channel Pinch Valve, the medium only resists in the tube and little
cross contamination, tube size recommend: 2mm*4mm.

Pinch Valve 1269
Single Channel Pinch Valve, the medium only resists in the tube and little
cross contamination, tube size recommend: 6mm*9mm.

Advantages of Pinch Valves
01
Hose easily cleaned, ideally for testing impurity sample, waste discharge

02
Suitable for inspecting samples contain impurities / particles or not

03
Applications in occasion which need to avoid cross contamination between
samples

What is a Pinch Valve Used for?

Keytos' pinch valve uses are as follows:

Keyto mainly offers the series 1224, 1213 and 1269 pinch valves. The pinch
valves are typically used in applications such as the discharge of samples
containing impurities (especially flocculent impurities) or particles, the pre-
treatment of water samples, electrolyte instrumentation, and the pharmaceutical
industry. The 1269 series of pinch valves are mainly used in the environmental
industry.

FAQs of Pinch Valves

Can a pinch valve regulate flow?
The pinch valve cannot be used to regulate flow because it is only available in
two states, fully open or fully close, and the degree of opening cannot be
adjusted at will.

How doe s a pinch valve stop flow?
Two types of solenoid pinch valve are available: N.C. and N.O.

Normally open valve(N.O.): the solenoid is powered to drive the pressure plate
action, then the pressure plate clamps hose tightly, so as to stop the flow.
Normally open valve(N.C.): the initial state of a normally close valve is that
of a stop-flow, and the stop-flow principle is the same as that of a normally
open valve. The difference is that normally open valve stops flow when powered
on and normally closed valve stops flow when powered off.

What are the components of pinch valve?
Main components of the pinch solenoid valve: solenoid, valve body, spring,
moving iron core, hose pressure plate, mounting plate.
