Knife Egde Gate Valve

*The SERIES 10 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
• Mining etc.

Sizes:
DN 2"/50mm to DN 24"/600mm (larger diameters on request)

Working pressure:
DN 2"/50mm to DN 10"/250mm: 150 psi / (10 kg/cm2)
• DN 12"/300mm to DN 16"/400mm: 90 psi / (6 kg/cm2)
• DN 18"/450mm: 75 psi / (5 kg/cm2)
• DN 20"/500mm to DN 24"/600mm: 60 psi / (4 kg/cm2)
• Standard flange connection: DIN PN 10 and ANSI B16.5 (class 150)

Note:
other flange connections are available on request such as:
• DIN PN 6
• DIN PN 16
• DIN PN 25
• BS "D" and "E"p ANSI 125

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 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 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 SCORPIO 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 SCORPIO 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.

The SCORPIO standard colour is Royal blue.

GATE SAFETY PROTECTION: *SCORPIO automated valves are provided with gate guards in accordance with Indian Safety Standards.
• The design feature prevents any objects from being caught accidentally while the gate is moving.
