Ductile iron diaphragm valve manufacturers in Italy

Valvesonly Europe is one of the best Ductile iron diaphragm valve manufacturers in Italy with quality valves catering to the distinct demands of most industries, ranging from water treatment, chemical process to pharmaceutical, food processing industries. Our valves are made in such a manner to provide satisfactory performance, excellent longevity, and minimum maintenance for optimal usage under hard conditions in heavy industries.
Ductile iron diaphragm valves find widespread applications in applications where accurate flow regulation and anticorrosive as well as wear resistance is crucial. Such valves are found to be rugged, strong, and capable of working with hostile media like acids, alkalis, and slurries.

What Makes Ductile Iron Diaphragm Valves Necessary?

In applications that need accurate and contamination-free control of flow, ductile iron diaphragm valves are not an option. Their use in processes that require exposure to abrasive or corrosive liquids and operations demanding high cleanliness and hygiene levels are particularly favourable to these valves. While the design of the diaphragm ensures a strong seal and eliminates leakage, ductile iron fabrication brings more strength and wear resistance to the product.
Ductile iron diaphragm valves are required by industries for:
Chemical Compatibility: Compatible to work with corrosive media and aggressive chemicals.
Applications in Hygiene: Ideal for the food processing and pharmaceutical industries.
Managing Abrasive Media: Prevents deterioration from slurries and particles.
Leak Prevention: By producing a tight seal, the diaphragm lowers the possibility of leaks.

Advantages:

Corrosion Resistance: Ductile iron accumulation with protective coatings withstands chemical corrosion and extends service life.
Leak-Free Construction: Even under extreme pressure, the soft diaphragm maintains a watertight seal to prevent leaks.
Maintenance Friendly: Repair and maintenance are made easier by the simple design and reduced number of moving parts.
General Utility: Practical for transferring gases, liquids, and slurries in a variety of industrial settings.
Strength and Toughness: Increased mechanical toughness and damage resistance are provided by ductile iron construction.

Functions of Ductile Iron Diaphragm Valves:

Flow Control: Controls the flow of fluids by increasing or decreasing the diaphragm.
Pressure Regulation: Regulates uniform pressure in the system by varying valve opening.
Isolation: Offers absolute shut-off and no backflow or contamination.
Directional Control: Controls the motion of fluids within multi-directional systems.

Key Components of Ductile Iron Diaphragm Valves:

Valve Body: Constructed out of ductile iron for maximum strength and anticorrosion properties.
Diaphragm: A flexible valve that regulates flow and forms an airtight seal.
Bonnet: Comprises the actuator and structure.
Stem: Links the actuator and diaphragm and enables mobility.
Seals and Linings: Offer protection against corrosion as well as abrasion.
Actuator: Manually operated, pneumatic, or electric, depending on full automation.

Ductile iron diaphragm valve types:

Weir-Type Diaphragm Valve: They provide close shut-off and good control and are designed to withstand corrosive and abrasive liquids.
Straight-Through Diaphragm Valve: Reduces turbulence and is ideal for high-flow application and low pressure drop.
Manual Diaphragm Valve: Has a handwheel or lever by which manual operation is made.
Pneumatic Diaphragm Valve: Works automatically by opening and closing upon the change of air pressure.
Electric Diaphragm Valve: For precise and remote control, this valve is driven by an electric motor.

In severe industrial usage, diaphragm valves of ductile iron are specially developed to achieve precise and reliable fluid flow control. Ductile iron body in the valve ensures high mechanical strength and immunity against damage due to corrosive or abrasive media. Rubber, PTFE, or EPDM are some types of elastomer diaphragms that ensure efficient flow control with a tight leak seal.
