Knife Gate Valve: Actuator & Handwheel
Your reliable partner for knife gate valves stainless steel & GG25 with handwheel, lever, pneumatic & electric actuator.
A knife gate valve is a valve that opens by lifting a gate out of the path of the liquid or medium. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully open. The gate surfaces can be parallel, but are usually wedge-shaped (to be able to exert pressure on the sealing surface).
Knife gate valves are used to shut off the flow of liquids or media and not to regulate flow, as is often the case with a globe valve. When fully open, the flow path in a typical gate valve is unobstructed, resulting in very low flow resistance. The size of the open flow path generally changes non-linearly as the gate is moved. This means that the flow rate does not change uniformly with the stroke of the spindle. Depending on the design, a partially open gate valve may vibrate due to the flow of liquid.
Fergo Knife Gate Valve
The knife gate valve is a versatile valve used in industry. Made from robust materials such as stainless steel and grey cast iron, the knife gate valve has a slide mechanism that is housed in a sturdy casing. The knife gate valve can be operated manually with a handwheel or automatically with pneumatic or electric actuators, including quick-closing options. The knife gate valve has a sealing on one or both sides with metal, NBR and EPDM seals. Fergo offers the knife gate valve with knife gate guide with integrated wiper action, PTFE-Synt./NBR/PTFE-Synt. and PTFE-Synt./EPDM/PTFE-Synt. packing. The knife gate valve is indispensable in industries such as the chemical industry, waste water treatment and food production in order to optimise efficiency and maintain system integrity. Easy to install and highly customisable, knife gate valves are the best solution for many pipework designs.
