Question 1

What Is A Pinch Valve?

Accepted Answer

A pinch valve is a type of fluid control valve. It applies a pinching force to the outer surface of flexible tubing. While pinching it collapses and seals the tubing to control fluid flow or pressure.
The main body of a pinch valve is not in direct contact with the gas or the liquid, and only the inside of the tube will have direct contact with the liquid and gas fluid flowing through. Therefore, the pinch valve is not in direct contact with the fluid.

Question 2

Gas Blending

Accepted Answer

Our QKL electronic proportional pressure regulator ( I/P converter) products help with gas blending applications that need repeatable pressure control. By controlling the pressure of each specific gas to a process, a tailored blend can be achieved. Here two QKL proportional pressure regulator ( I/P converter) are controlling the pressure of two types of media in a gas blending application. Our proportional pressure regulator can also work in tandem with the proportional flow control valve to stabilise the inlet air pressure, and thus stabilise the flow rate after the flow control valve.
We also provide proportional flow control valve in this application, which can directly replace those of Burkert or Festo.

Question 3

Why Use Pinch Valves?

Accepted Answer

Industry leaders looking for a low-maintenance and more cost-effective solutions for controlling liquids, gases, slurries and powders (incl. corrosive media) in a pipeline are turning to pinch valves over traditional valves (diaphragm valves, ball valves, butterfly valves, needle valves, etc.) Unlike traditional valves, pinch valves feature a straight-through flow, very little pressure drop over the valve, and full shut-off of media in the tube, making it the most practical and efficient solution for various ON/OFF flow control applications.

Question 4

Glass Bottle Blow Molding

Accepted Answer

This sketch shows a QKL Electronic proportional pressure regulator ( I/P converter) piloting a volume booster in a glass bottle blow molding application. Most glass bottles are manufactured via the "press & blow" method. In this method the pressure regulator is used at the final stage to fill air into the molten glass in a mold.

Our proportional pressure regulator is best suited for this application due to its high flow rate, fast response time, and high accuracy. Our regulators are capable of modulating from 2 bar to 65 bar with accuracy of 0.25% FS. (higher pressure range can be customised upon request)

QKL electronic pressure regulator can directly replace:
Proportion Air ( QB3H, QBS, GX, QBX, QPV, QB2 ), Festo ( VPPM, VPPL, VPPE, VEAA, VEAB, VEMD ), SMC (ITV1000, ITV2000, ITV3000), Clippard (Cordis), and ASCO (Sentronic)

Question 5

Why Use Proportional Pinch Valves?

Accepted Answer

See below for pressure curves representing 2-way (ON/OFF) control versus proportional control. If you need the option to vary or hold flow or pressure in your system a proportional valve allows you flexibility to adjust the valve opening from full open to closed or anywhere in between.

food manufacturing equipment

Across a variety of markets and industries, maintaining the integrity of the fluid or media passing through non-contact technology is a driving factor in choosing pinch valves. As technologies evolve, we see more and more applications that require increasingly demanding performances that are just not achievable with conventional pneumatic or solenoid pinch valves; there is a demand for proportional controls in order to regulate and monitor processes with greater accuracy, speed, and delivery. Regulation of the fluid or media is necessary and can be limited to several factors, including flow, net volume, temperature, positive or negative pressure, and viscosity.

Filtration and dispensing applications benefit immensely from proportional pinch valves. Filtration is a method used to separate particles from a fluid. Filters require precise regulation of flow, along with monitoring positive and negative pressure at the membrane as the process occurs. Material build-up as the filter does its job means that increased flow or pressure may be needed in order to maximize the filters usefullness to a maximum point.

Question 8

Airbag Lifting

Accepted Answer

QKL electronic proportional pressure regulator( I/P converter) used to inflate air bags to raise a table. Pneumatically operated tables and lifts require air bag pressure control that is accurate and repeatable. These tables and lifts require less maintenance than conventional hydraulic lift tables, since there is no fluid to leak and contaminate processed goods.

Our proportional pressure regulator is best suited for this application due to its high flow rate, fast response time, and high accuracy. Our regulators are capable of modulating from 2 bar to 65 bar with accuracy of 0.25% FS. ( higher pressure range can be customised upon request)

Our electronic pressure regulator can directly replace:
Proportion Air ( QB3H, QBS, GX, QBX, QPV, QB2 ), Festo ( VPPM, VPPL, VPPE, VEAA, VEAB, VEMD ), SMC (ITV1000, ITV2000, ITV3000), Clippard (Cordis), and ASCO (Sentronic)
