"With its sealing capabilities and its ability to reduce stress on the packing chamber, the P77 ensures reliable and efficient operation,” said Dale Speggen, VP of Specialty Valves for Mueller. “We are proud to offer this valve, which sets a new standard for performance and reliability."
The P77 Knife Gate ensures a drip-tight shutoff, preventing the buildup of solids, regardless of line pressure. The valve is designed to eliminate confusion regarding the direction of isolation, providing clarity and ease of use in demanding industrial environments.
The P77 Knife Gate Valve is designed with multiple rows of packing to reduce stress on the packing chamber, enhancing the longevity and reliability of the valve. The integrated PTFE gate guide reduces wear on the packing, preventing blockages and flow disruptions with its non-stick properties.
Featuring an EPDM perimeter cartridge seat, the P77 Knife Gate Valve resists chemicals and high temperatures while preventing leakage and protecting downstream equipment. By reducing leak paths and extending the life of the packing, this valve minimizes maintenance requirements and ensures smooth operation.
The heavy-duty cast stainless steel body is resistant to deflection from line loads and internal pressure, further enhancing the valve's performance and longevity. The P77 Perimeter Seated Bi-Directional Knife Gate Valve has applications across various industries, including pulp and paper, mining, water and wastewater, and food and beverage.
