SERVAL VALVES
For interception of liquid, gas, and solid products

Serval

ServalSERVAL valves have a total open passage. No losses of charge, no problems with abrasive products. The interception sleeve warrants a watertight closure, even with foreign objects.

Advantages

• Extremely simple operation, only one movable element
• Watertight closure
• During the opening operation, no possible jam takes place
• Movable self-cleaning element prevents encrustations
• No side play, they are in-line with the pipes

Closed valve

Valvola chiusa

With the pressure of a fluid (air, water) injected in the valve's body, the gasket compresses itself until the complete closure of the passage.
Open valve

Valvola chiusa

As soon as the pressure injected in the valve's body stops, the gasket takes again its cylindrical shape opening the passage to the regular flow of product.

Technical Featurest

• Body and flanges from aluminium or stainless steel
• Sleeve in different types, to 170°C (see related sheet)
• Operating pressure 6 bar
• Control pressure: 1,8 - 2,5 bar over the operating pressure (depending on the sleeve quality)
• Threaded connections, also made in different materials are available
