Product Description

Product Description

Q71F-25 Forged Steel Wafer Flanged Italy Type Thin Ball Valve

The Q71F-25 Wafer Flanged Italy Type Thin Ball Valve adopts a floating ball structure, the floating ball valve has a simple structure and good sealing performance, but the ball bears all the load of the working medium and is transmitted to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. When subjected to high pressure impact, the ball may deviate. This structure is generally used for medium and low pressure ball valves. The main characteristics of a ball valve are its compact structure, reliable sealing, simple structure, and easy maintenance. The sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium and is easy to operate and maintain. It is suitable for general working media such as water, solvents, acids, and natural gas, and is also suitable for media with harsh working conditions. The contact parts between the ball valve and the medium are made of corrosion-resistant stainless steel. This soft sealed ball valve is used for general working media such as water, solvents, acids, and natural gas, and is also suitable for harsh working conditions such as corrosive media such as oxygen, hydrogen peroxide, nitric acid, acetic acid, caustic soda, etc. Soft sealed stainless steel flange ball valves are commonly used in medical and health equipment, food machinery, chemical acid and alkali corrosive equipment, and pipeline systems.

Q71F-40 Wafer Type Italian Thin Ball Valve

Main Features and Specifications:

Compact structure, easy installation

Wafer connection: The valve body has no flanges and is clamped between pipeline flanges using long bolts. It is lighter, shorter, and takes up less space than flanged ball valves.
Suitable for piping systems with limited space.

Superior Pressure Rating:

• Forging process eliminates internal defects (porosity, sand holes, shrinkage) common in castings
• Maximum working pressure up to PN64 – significantly higher than cast wafer ball valves
• Ideal for high-pressure applications with greater safety margin

Wide Material Selection

• Available materials: A105 (Carbon Steel), F304 (SS304), F316 (SS316)
• Suitable for various media (water, oil, gas, mild corrosive fluids) and temperature ranges
Applicable working conditions:

Pressure: Generally suitable for PN10–PN40 (1.0–4.0 MPa). Wafer type is not recommended for high pressure applications.
Temperature: Depends on ball valve seat material (e.g., PTFE, PEEK, EPDM, etc.), typically -20°C to +180°C.
Media: Water, oil, gas, mild acids/alkalis, dust, etc.
