Knife gate valve, type 7300
Technimex concentric butterfly valves are designed and manufactured to have a mix of structural stability, flow efficiency and effective sealing. The valves have a low weight and a compact design. They are provided with replaceable sleeves (optional; vulcanized sleeves) and the body material will fit to the specific fluid for a long operational life. The valves are easy to operate and require little maintenance. Only a quarter turn is needed to fully open or close the valves. Technimex butterfly valves can be operated manual, electrical, pneumatic or hydraulic.
