Resilient Seat Knife Gate Valves
一:
HEAVY DUTY cast ductile iron split body and yoke for the most rugged service.
Replaceable natural rubber seat provides a BI-DIRECTIONAL BUBBLE TIGHT SEAL across gate from 0 to 150 PSI.
Optional EPDM and Buna seats also available.
Resilient seat is flush with the bottom of the port ELIMINATING any pockets in the bottom of the valve to collect material in media such as slurries, pellets or powders.
Resilient seat has a molded-in steel reinforcement and is bolted in place to prevent it from being shifted out of position by gate movement.
Full packing seal around gate to prevent packing leakage.
Enclosed brass stem bushing provides reduced operating torque and protection of stem bushing from harsh environments.
Resilient seat replacement is quick and easy.
Full port ID.
Machined stainless steel gate for corrosion resistance and durability.
Available in sizes from 2" to 16" diameter.
Meets MSS-SP-81 face to face dimension and flange dimensions.
150 PSI working pressure.
Exterior and interior of entire valve coated with a heat activated powder coating.
二:
Heavy Duty fabricated carbon steel or stainless steel body, yoke and packing gland.
UHMWPE, PTFE, or Polypropyoene liner and seat provide bi-directional tight shutoff.
Three-piece field replaceable liner/seat.
Available in standard pressure ratings of 150 psi or 300 psi.Higher pressure ratings and custom designs also available.
ANSI B16.5 Class 150 or 300 flange bolting.
Stainless steel gate and stem for corrosion resistance and durability. Special Alloys, coatings and surface hardening also available.
Superior packing arrangement provides improved sealing performance in high cycle applications.
Positive SHUT OFF in BOTH DIRECTIONS.
Full port inside diameter in all sizes. Custom port sizes and designs available.
Minimum 4 bolt packing gland design to assure proper gland alignment in all sizes.
Meets Tappi standard TIS 405-8 and MSS SP-81 for stainless steel bonnetless, flanged, wafer knife gate valves.
Standard with manual handwheel. Also available are chainwheel, bevel gear, pneumatic/ hydraulic cylinder of electric motor.
Recommended for applications requiring superior corrosion and/or erosion resistance, heavy slurry and high cycle application
三:
HEAVY DUTY cast ductile iron body and yoke for the most rugged service.
Solid lug body design.
Positive SHUT OFF in BOTH DIRECTIONS. URETHANE LINER and seat provides a BI-DIRECTIONAL BUBBLE TIGHT SEAL across gate from 0 to 150 PSI.
Smooth flow--non-clogging FULL PORT design. SEAT IS FLUSH with the bottom of the port ELIMINATING any pockets in the bottom of the valve to collect material in media such as slurries, pellets or powders.
URETHANE LINER is a one piece molded in place full body liner.
STAINLESS STEEL GATE for corrosion resistance and durability.
STAINLESS STEEL STEM for corrosion resistance.
EASY CONVERSION from handwheel operator to cylinder, bevel gear or electric motor operator using standard cast yoke.
ENCLOSED BRASS STEM BUSHING provides reduced operating torque and protection of the stem bushing from harsh environments.
FULL PACKING SEAT around gate to minimize packing leakage.
MSS-SP81 face to face dimension and flange dimensions.
FULL PORT ID.
Time proven TOWNIPRENE urethane liner for the best abrasion resistance in tough applications.
四:
