Pinch Valve

Australian Valve is the top Pinch Valve Manufacturer & Supplier in Australia. A pinch valve is a type of control valve that is used to regulate fluid flow in pipelines. It operates by using a mechanical squeezing action to control the flow of fluid through a flexible tube or hose. The valve consists of a body that houses a pinch mechanism, which is typically operated by an external actuator, such as an air cylinder or electric motor. When the pinch mechanism is activated, it compresses the flexible tube, effectively shutting off the flow of fluid. When the mechanism is released, the tube returns to its original shape, allowing the fluid to flow freely again. Pinch valves are commonly used in applications where corrosive, abrasive, or toxic fluids are present, as they are less prone to leakage or contamination compared to other types of valves.

Types

• Pneumatic pinch valves: These valves are powered by compressed air and are typically used in applications where a fast response time is required.
• Hydraulic pinch valves: These valves are powered by hydraulic fluid and are commonly used in high-pressure applications.
• Electric pinch valves: These valves are powered by an electric motor and are typically used in applications where precise control is required.
• Manual pinch valves: These valves are manually operated and are commonly used in low-volume applications.
• Soft-seated pinch valves: These valves have a soft inner lining that is typically made from elastomers, such as silicone or rubber. They are commonly used in applications where low pressure drop is required.
• Hard-seated pinch valves: These valves have a hard inner lining that is typically made from metals, such as stainless steel. They are commonly used in applications where abrasive or corrosive fluids are present.
• Sleeve pinch valves: These valves use a flexible sleeve as the inner lining and are commonly used in applications where low pressure drop is required.
• Flange pinch valves: These valves have flanged connections and are commonly used in applications where high pressure drop is required.

Advantages

• Abrasion and corrosion resistance: Pinch valves are typically made from materials that are resistant to abrasive and corrosive fluids, making them suitable for use in harsh environments.
• Low maintenance: Pinch valves are designed to be low maintenance, as they have few moving parts and do not require frequent replacement of seals or gaskets.
• Versatility: Pinch valves can handle a wide range of fluids, including corrosive and abrasive fluids, making them suitable for use in a variety of industries, such as chemical, water treatment, and mining.
• Easy to control: Pinch valves can be easily controlled by an external actuator, such as an air cylinder or electric motor, making them ideal for applications where precise control is required.
• Durable: Pinch valves are designed to be durable and can withstand high pressure and high temperatures, making them suitable for use in demanding applications.
• No dead space: Pinch valves have no dead space or pockets where fluid can become trapped, reducing the risk of contamination and making them suitable for use in sanitary applications.
• Cost-effective: Pinch valves are typically less expensive than other types of valves, making them a cost-effective solution for many applications.
