The Pneumatic Piston Valve (Flanged, Y-Type) is designed as a valve that operates with the assistance of compressed air to control the flow of liquids or gases. This type of valve is generally preferred in industrial systems that require high flow capacity and fast response times. The piston or diaphragm in the system is actuated by compressed air, allowing the flow to be opened or closed. Its body is made of stainless steel, and the flanged connection system enables easy integration into piping lines. The operating principle varies depending on whether it uses a single-acting or double-acting actuator system. This product range is offered by Unox according to high-quality standards.

Technical Specifications and Structural Details

The valve body is manufactured from AISI 316 stainless steel, while the actuator body is made of 304-grade steel. The flanged connection standard provides secure installation within systems. It is designed as a single-acting, normally closed type, held in the closed position by spring force. When compressed air is applied, the valve opens, and it automatically closes when the air is cut off. In double-acting models, air pressure is used for movement in both directions. Production is also available with the standard BSP threaded option. The operating temperature can reach up to 180 °C, and the supply pressure is provided in the range of 3–8 bar.

Application Areas

Pneumatic piston valves are used for flow control in a wide range of industries. They are actively employed in beverage filling systems, water and wastewater treatment plants, and chemical and petrochemical facilities. They are also commonly preferred in textile dyeing and printing systems, high-temperature disinfection lines, and foam production systems. These valves provide high performance in the food, energy, gas, and industrial automation sectors.

Product Advantages and Efficiency

Thanks to its Y-type body design, the flow area is enlarged, allowing up to 30% smoother flow. This design provides high resistance against water hammer. The body self-lubricates and self-adjusts, ensuring long service life and low maintenance costs. The cylinder section can rotate 360 degrees and is made entirely of stainless steel, guaranteeing the system’s durability under all environmental conditions. It can be easily integrated into automation systems, maximizing process safety. Technical drawings and product documents are available through Unox Online.
