Description

Pratt Industrial LV0677A6E-MH 6 in. 316 Stainless Steel LVC Figure 77 Knife Gate Valve Description

The Pratt Industrial Figure 77 Knife Gate Valve is a bi-directional resilient seated valve designed for dependable shut-off in demanding industrial environments. Featuring a cast stainless steel body and gate, this valve incorporates a Buna-N rubber seat that provides a drip-tight seal across the gate from 0 to 150 PSI. Its compact wafer configuration meets TAPPI and MSS standards, while the full port design ensures smooth, non-clogging flow. Built for durability, the valve resists deflection under heavy loads and internal pressure, and offers easy conversion from manual handwheel operation to hydraulic, pneumatic, or electric actuators. Precision machining and corrosion-resistant materials ensure long-lasting performance in harsh conditions.

Features

• Heavy-Duty Stainless Steel Construction: Cast stainless steel body, packing gland, and yoke deliver strength and corrosion resistance for harsh environments.
• Bi-Directional Drip-Tight Seal: Standard Buna-N resilient seat ensures tight sealing from 0 to 150 PSI, with optional EPDM, Viton, and Neoprene materials available.
• Compact Wafer Design: Meets TAPPI and MSS face-to-face standards for space-saving installation.
• Smooth Flow Full Port: Non-clogging design eliminates pockets that collect media, ensuring efficient operation.
• Versatile Actuation Options: Easily converts from handwheel to hydraulic, pneumatic, electric motor, bevel gear, chainwheel, or fail-safe spring cylinder using the existing yoke.
• Enhanced Durability: Enclosed bronze stem bushing reduces operating torque and protects against wear, while stainless steel stem resists corrosion.
