Stainless Steel 304 Knife Gate Valve 14'' 150 LBS ASME B16.34
Quick Details:
| Product Name | Material |
| Valve Body | Ductile iron, Carbon steel, Stainless steel |
| Knife | Stainless steel |
| Stem | Stainless steel |
| Handwheel | Cast iron |
| Sealing | NBR/EPDM/PTFE or Metal Seat |
Product Description
knife type gate valve has the advantages of simple and compact structure, reasonable design, light material,
reliable sealing, light and flexible operation, small size, smooth passage, small flow resistance, light weight,
easy installation and easy disassembly. The working pressure is 1.0MPa2.5MPa, and the working temperature
is normal when the temperature is-29-650°C. The knife-type gate valve has a shearing function, which can scrape
off the adhesive on the sealing surface and automatically remove debris. The stainless steel gate can prevent sealing
leakage caused by corrosion.

Product charateristics:
It's characterized by its compact design,being space-effective,low
price,easy installation, complete protection from
abrasion and seizure,user-friendly maintenance and operation,long service life and free actuator options.
BODY:
· Cast-in guide claws at the port bottom for gate fixture, instead of a groove, eliminates potential valve shutoff clogging
while providing tighter seal. The guide claws also push gate to seat for tight seal in closed position.
· Integral body design ensures easy assembly and 0 shell leakage.
· Full port design minimizes pressure drop and maximize flow capacity.
· PTFE resilient points against gate eliminate metal-metal contact between gate and bo dy.
SEAT:
· Side-entry seat is replaceable, reducing the cost of maintenance.
· L-shape seat retainer locks seat into valve body and covers seat side to prevent direct flow flushing.
GATE:
· Beveled knife edge provides strong cutting stress and tight sealing.
· Gate thickness can be increased to meet higher pressure.
· Gate surface is well polished at both sides for tight seal and less jamming.
· Gate is hard chrome coated for metal sealing valve.
STEM:
· Stem cover is available to ensure long service life for stem.
· Two thrust bearings minimizes torque for operation.
· Grease nipple is available to ease bearing lubrication.
