The Ex (Ser.10) is a unidirectional knife gate wafer valve designed for general industrial service applications. The design of the body and seat assures non-clogging shutoff on suspended solids in industries; industries such as Pulp and Paper, Wastewater, Chemical, Food and Beverage, Bulk Handling, Mining and more.

BODY: Wafer style cast monoblock with raised faces and reinforcing ribs in large diameters for
extra body strength. Internal cast-in gate wedges and guides allow for a tighter shut-off
between gate and seat. Full port design for greater flow capacity and minimal pressure
drop. The internal body design avoids any accumulation of solids that would prevent the
valve from closing.
GATE: Stainless steel gate. 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. The thickness and/or material of the gate can be changed on request for
higher pressure requirements.
SEAT: Unique design that mechanically locks the seal 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 fibre 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 for installation purposes 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
applied by means of an electrostatic process, making the valves corrosion-resistant with a high quality
finished surface.The ORBINOX standard colour is RAL-5015 blue.
GATE SAFETY PROTECTION: ORBINOX automated valves are provided with gate guards in accordance with EU Safety
Standards. The design feature prevents any objects from being caught accidentally while the gate
