Wafer Style Knife Gate Valve EX Model 10 Series DESCRIPTION
The EX Model 10 Series 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 • Food and Beverage • Mining
• Chemical plants • Bulk handling
FEATURES • Body: Wafer style cast monoblock with raised face and with reinforced ribs in larger diameters for extra body strength. Internal cast-in gate wedges and guides allows for tighter shut-off. Full bore 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 material of the gate can be changed for higher pressure requirement. • Seat: (resilient) Unique design that mechanically locks the seat in the internal of the valve body with a stainless steel retainer ring. Standard EPDM also available in different materials such as Viton, PTFE, etc.
• Packing: Long-life packing with several layers of braided fiber plus an EPDM o-ring, with an easy access packing gland ensuring a tight seal. Long-life braided packing is available in a wide range of materials. • Stem: The standard stainless steel stem offers a long corrosion resistant life. For rising stem handwheel actuators only, a stem protector is provided for additional protection against dust while the valve is in the open position. • Actuators: All actuators supplied by ORBINOX are interchangeable, and supplied with a standard mounting kit to allow for installation on site. • Yoke or Actuator Support: Made of Epoxy coated steel (stainless steel available on request). Compact design makes it extremely robust even under the most severe conditions.
• Epoxy Coating: The epoxy coating on all ORBINOX cast iron and carbon steel valve bodies and components is electrostatically applied making the valves to be corrosion resistant with a high quality finished surface.
