VALVE SOLUTIONS IN MORE THAN 70 COUNTRIES WAFER STYLE KNIFE GATE VALVE The EK model knife gate is an uni-directional wafer valve designed for general industrial service applications. The design of the body and seat assures non-clogging shut off on suspended solids in industries such as: • Pulp and Paper • Power plants • Wastewater treatment plants • Chemical plants • Food and Beverage • Bulk handling Sizes: DN 50 to DN 1200 (larger diameters on request) Stand ard flange connection: DIN PN 10 Note: other flange connections are available on request such as: All valves are tested prior to shipping in accordance with the standard developed by the Quality Control Department at STANDARD PARTS LIST Reserves the right to change specifications without notice EK-1 ORBINOX SA Pol.

BODY: Wafer style cast stainless steel monoblock with raised face, with reinforced ribs in larger diameters for extra body strength. Internal cast-in gate wedges and guides allows for tighter shut-off. Full port design for greater flow capacity and minimal pressure drop. Internal design avoids any build up of solids that would prevent valve from closing. GATE: Stainless steel gate as standard. Gate is polished on both sides to avoid jamming and seat damage. Bottom of the gate edge is machined to a bevel to cut through solids for a tighter seal in the closed position. On request: thickness and/or...

Gate guards for actuators with proximity switches (Fig.1): It has been made a special design which allows horizontal and parallel mounting of the proximity switches including protection to them. Bonnet: Assures tight sealing to atmosphere for using with hazardous gas or fluids. Reduces packing maintenance. Flush ports: Allow for cleaning of solids trapped within the body cavities that can obstruct the flow or prevent the valve from closing. Purging can be made with air, steam, liquids, etc. depending on the process. Other materials of construction: Special alloys such as 1.4449 (AISI 317), 1.4547...
