Description
ANSI **0LB knife gate valve is an uni-directional 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:
·Wastewater treatment plants
·Chemical plants
·Food and Beverage etc.
Body:
Wafer style cast 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 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 NBR, Viton,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.
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 JCS 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.
Materials:
Body:WCB,**4,**6,**6L
