Perimeter Seated Bi-Directional Knife Gate Valve

Specifications:

• Handwheel: convertible to hydraulic or pneumatic cylinders, bevel gears, chain wheels, electric motors, or fail-safe spring cylinder operators
• Bronze stem nut retainer assures the stem nut remains securely fastened to the valve stem during operation.
• Stainless steel stem resists corrosion while the enclosed bronze stem bushing offers protection against harsh environments and reduces operating torque, particularly after dormancy.
• Heavy duty cast stainless steel yoke inhibits deformation or damage under extreme loads.
• Full-circle packing reduces potential leak paths, minimizes the need for adjustment, and extends the life of the packing
• Rubber-seated gate delivers a secure bi-directional drip-tight seal
• EPDM perimeter cartridge seat resists chemicals and high temperatures
• Integrated Teflon gate guide reduces stress and wear on the packing, while also preventing blockages and flow disruptions with its non-stick properties.
• Multiple rows of packing provides better seal performance and provides redundancy.
• Heavy duty cast stainless steel body resists deflection from line loads and internal pressure.
• Pressure rating up to 150 psi as required by MSS SP-81
