Features:
Sizes: 2” –24”/DN50 –DN600.
Bonneted Knife Gate Valves reduce fugitive emissions and packing leakage.
Cast Stainless Steel body, gland and yoke.
Wiper between body and bonnet prevents solids from entering bonnet.
Bonnet design pressure same as valve pressure rating of 150psig/10barg.
Standard TFE lubricated synthetic packing (TLSP) rated for 260° C and a pH range of 3-11.
Heavy duty body design resists deflection from line loads and internal pressure.
Gate design withstands full 150psig/10barg rated pressure as required by MSS SP-81.
Body cavity, seat configuration, and beveled gate design provide shut off capability in thick media such as pulp stock and slurries, or solid media like pellets and powders.
Heavy duty cast Stainless Steel yoke prevents bending or twisting under extreme loads.
Easy conversion from handwheel operator to pneumatic or hydraulic cylinder, bevel gear, or electric motor operator using existing cast yoke.
Enclosed Bronze stem bushing reduces operating torque and protects the stem bushing in harsh environments.
