The SERIES 20 knife gate is a uni / bi directional lug type valve designed according to the MSS-SP-81 and TAPPI TIS 405-8 standard for industrial service applications. The design of the valve allows for a tight shut off in services with solids in suspension in industries such as:
Pulp and Paper Chemical Plants Power Plants Waste Water Mining Food and Beverage Sizes: 2" to 24" (larger diameters on request) Working Pressure: 2 ?to 24 150 PSI Standard Flange Connection: ANSI B16.5 (class 150) and DIN PN 10 All valves are tested prior to shipping in accordance with the manufacturers specification developed by the Quality Control department at Orbinox.?
DESIGN FEATURES BODY:
One piece integrally cast stainless steel body with raised face flanges and reinforced body ribs in larger diameters for extra body strength. Internal cast gate wedges and guides allows for tighter shut off. Full port design according to MSS-SP-81 and TAPPI TIS 405-8. Internal design reduces any build up of solids that could prevent valve from closing.
GATE:
Blade polished on both sides for a tighter seal in the packing chamber. Machined beveled gate end shears through solids for a tighter shut off.
SEAT:
Unique design that mechanically locks the seat inside the valve body with a stainless steel retainer ring. Standard EPDM seat; available in different materials such as Viton, PTFE, etc.
PACKING CHAMBER:
Standard braided PTFE impregnated fiber with EPDM O-ring for a tighter seal. Smooth chamber and cast gland follower with equally distributed gland bolts provides uniform compression of packing.
STEM:
Corrosion resistance stainless steel stem. Single pitch Acme thread reduces torque on handwheel operator and eliminates installation of a gear operator on larger diameters. Standard stem protector on all handwheel actuators gives additional protection against dust while the valve is in the open position. ACTUATORS:
All Orbinox actuator models are supplied with a standard mounting kit to allow easy installation on site.
YOKE & SUPPORT PLATES:
EPOXY coated steel (stainless steel available on request). Compact design makes it extremely robust even in the most severe conditions.
EPOXY COATING:
The electrostatic applied epoxy coating on all ORBINOX cast iron and carbon steel valve bodies and components make the valves corrosion resistant.
GATE SAFETY PROTECTION:
Gate guards are available upon request for areas where safety is a concern. The design feature prevents any objects from getting caught accidentally while the gate is moving.
