Diaphragm valves

We invite you to explore our extensive range of diaphragm valves. They play an incredibly important role in the field of industrial control devices. The construction of a diaphragm valve is based on the use of a flexible membrane that separates the fluid chamber from the control chamber. This makes it indispensable in many situations. Diaphragm valves are widely used in the chemical, pharmaceutical, food, and many other industries where precise flow control is essential. We assure you that GTM Process Valves diaphragm valves are distinguished by the highest quality and precision in craftsmanship. This translates into their reliable and long-lasting operation. We are confident that all our products will meet your every expectation!

The construction of a diaphragm valve

The construction of a diaphragm valve is designed to allow precise control of substance flow while providing protection against potential leaks or damage. How exactly is a diaphragm valve constructed?

1. The diaphragm – a flexible part of the valve that separates the fluid chamber from the control chamber. It is made of materials with high elasticity, such as rubber, plastics, or metallic sheets. The diaphragm responds to forces of pressure, stretching, or bending, regulating the flow of substances.
2. The body – the structure of the valve where the diaphragm is housed. The body can be made of various materials such as stainless steel, aluminum, or plastics. It provides stability and protection for the internal chambers of the valve.
3. The fluid chamber – the space on one side of the diaphragm where the substance flows. The fluid chamber is connected to pipes or pipelines that transmit the substance to and from the valve.
4. The control chamber – the space on the other side of the diaphragm, responsible for controlling the flow of the substance. Various control methods can be used in the control chamber, such as pneumatic actuators, electromagnets, or manual valve adjustment.
5. Seals – diaphragm valves may have additional sealing elements, such as sealing rings, which prevent substance leakage. Seals are important for maintaining tightness and eliminating flow losses.
6. Control elements (optional) – in some cases, diaphragm valves may be equipped with control elements such as pneumatic actuators, electromagnets, or buttons, allowing remote or automatic control of substance flow.

Diaphragm valve – principle of operation

The diaphragm valve operates based on simple yet effective principles that enable precise control of substance flow. The key element is the flexible membrane, which separates the fluid chamber from the control chamber. During substance flow, balancing forces such as spring force, pressure force, and control force influence the behavior of the membrane.

The spring force causes the membrane to return to its original position after external forces act upon it. The pressure force of the substance in the fluid chamber affects the displacement of the membrane and flow regulation.

In the case of diaphragm valves with control elements such as pneumatic actuators, the control force influences the movement of the membrane and controls substance flow. Thanks to these principles, diaphragm valves enable precise regulation of substance flow.

When the membrane is immobilized, the flow is blocked, and when the balancing forces are properly equilibrated, the membrane opens, allowing for fluid to flow freely through the valve. This flexible operation of the diaphragm valve, combined with control elements, enables effective control of substance flow in various industrial applications.
