HG-Stahl Knife Gate Valves are predominantly preferred in factories where fluid freezing issues occur, viscosity is high, and in paper and cardboard manufacturing facilities.

The critical point in knife gate valves is that, in addition to having a thin construction, the products must also be robust and durable. In cases of valve flexing, changes in the sealing element may lead to leakage in the products.

In the case of custom-designed HG-Stahl Knife Gate Valves, finite element methods (CAE) are carefully examined, and potential flexing in the body structure due to high bolt torque during transport or assembly is evaluated before finalizing the design and proceeding to production.

Our Knife Gate Valve products, produced in partnership with the German company Lohse GmbH, are now utilized in various facilities worldwide.

The materials used in the design of HG-Stahl Knife Gate Valves play a critical role depending on the operating conditions of the valve. For applications involving abrasive fluids or contact with chemicals, HG-Stahl extends the lifespan of the valve by using stainless steel, duplex, or polymer-coated materials. Additionally, knife gate valves offer compatibility with automation systems, with options for electric or pneumatic actuators, providing remote control and monitoring capabilities. This feature also minimizes maintenance costs in your operations.
