Iris Diaphragm Valve (IDV) utilizes a concentrically closing fabric or rubber diaphragm to accurately control the flow of powders and granular material.Ideal for "trickle-feed" applications and shutting off against a flow of material.

The Iris Diaphragm Valve is mainly used to control the opening and closing of the free flowing dry material flow in the straight fall system. iris valves can be used in many industries including chemicals, dairy products, food, mining plastics and medicine. Iris valves are often used to transport brittle materials.

Aperture valve or iris valve is mainly used in jumbo bag unloading station, which can control the volume of material we needed and in addition, it can reduce the possible dust pollution.

Its center is made of cloth or TPU which forms a cloth bag. It has the characteristics of high sanitary grade, detachable diaphragm, compact shape and quantitative opening and closing. It consists of a valve body, upper gland, inner gland, lower gland, rotating parts and diaphragm. Together they form a thorough hole and it's called a valve channel.

It has a pneumatic form, which can be operated by adding the cylinder as the power source, to savie manpower, and improve the completion of the throttling action. Eventurally it prevents the waste caused by incomplete operation.

Material: carbon steel, aluminum, 304 stainless steel, 316 stainless steel, etc., it can be customized according to customers' requirements.

The iris valve is mainly used to control the opening and closing of the free flowing dry material flow in the straight fall system.

In addition to controlling the flow rate and preventing material loss, iris valves can also be used to regulate pressure and optimize feeding accuracy. They can be operated manually or automatically, depending on the specific application and the level of precision required.

Outlet valve for Silos, Bins, Hoppers and Chutes

Can be used for In-Line applications

Discharge from Sifters, Ribbon Mixers, and Double Cone Blender outlets

For manual bagging of material where frequent operation is involved

Controlling discharge from containers into weigh hoppers

Closing the 'necks' of Big Bags where a valve smaller than the Series JS12 is required

The valve is also useful for closing the necks of big bags, where standard discharge valves may be too large. In this way, it can be used to ensure reliable and precise control over the flow of materials in a broad range of applications.

Iris Diaphragm Valve, also known as diaphragm valve or adjustable aperture valve, is a type of valve used to regulate the flow of controlled medium in a pipeline system. It features a circular diaphragm with an adjustable aperture that can be opened, closed, or partially opened by rotating a handle or adjuster.

Iris valve has several advantages over other types of valves, such as:

1. Precise and adjustable flow control: The iris valve can achieve precise and adjustable flow control by changing the size of the aperture, thus enabling accurate regulation of flow rate and velocity.

2. Efficient and reliable sealing: The circular diaphragm of the iris valve can be designed to fit tightly against the valve body to provide efficient and reliable sealing, even in high-pressure or high-temperature applications.

3. Low head loss: The iris valve has a low-pressure drop or head loss, which means that it causes minimal resistance to the flow of fluid, resulting in reduced energy consumption.

4. Easy installation and maintenance: The iris valve is easy to install and maintain, as it features a simple structure with only a few moving parts, and it can be easily disassembled for cleaning or replacement.

5. Versatile application: The iris valve can be used in a wide range of applications, including water treatment, chemical processing, pharmaceuticals, food and beverage, and many other industries.

In conclusion, the iris valve offers precise flow control, reliable sealing, low head loss, easy installation and maintenance, and versatile application, making it an excellent choice for many pipeline systems.

Iris diaphragm valve - Characteristics

Robust construction:
Designed for continuous operation, suitable for various duties. Simple installation and commissioning.

Hysteresis-free and excellent regulation characteristics:
are prerequisites for regulating tasks. This is achieved by the continuously variable aperture from 0 – 100%, similar to the IRIS diaphragm of a camera, always maintaining a central flow and by an enhanced segment edge design.

Non-clogging due to the free, central flow design and the automatic, self-cleaning feature of the segment edges during valve operation. Flushing connections are provided.

Examples of applications:
Air, sugar, suspensions, sewage, sludge, paper stock, drinking water, etc.
Energy cost savings and low noise emission through enhanced design. Fixed throttling apertures and imprecise regulating methods cause unnecessary pressure losses and energy costs. Due to the almost free passage and low turbulences in our valve these are reduced to a minimum. Because of an advantageous basic characteristic, we can operate in an energy saving manner, i.e. with optimal valve apertures.
