Series A WIVO Manual Knife Gate Valve features a robust design, available with either a cast iron or fabricated steel body, stainless steel gate, and two durable elastomer cartridge slurry seats. These seats come in various elastomers for enhanced chemical compatibility and abrasion resistance. The valve's port is formed by two halves of the cartridge slurry seats, ensuring a reliable seal. A flush area at the valve base includes a clean-out port for easy maintenance.
This valve offers bi-directional shutoff and is equipped with heavy-duty topworks for long-term durability. Its simple design minimizes the need for costly overhauls, unscheduled downtime, and expensive replacement parts. The only parts that need replacing over time are the slurry sleeves and packing.
For sizes 3"-12", WIVO Valves are equipped with a standard handwheel mechanism, featuring cast handwheels, machined 303 stainless steel stems, yoke sleeves, and thrust washers designed to reduce operating torque. For sizes 12" and above, it's recommended to use a 4:1 bevel gear actuator to minimize rim pull and optimize valve operation.
Pneumatic actuators are also available, providing excellent abrasion resistance under high-cycle conditions. These actuators self-clean with each cycle, making them ideal for automated plants. Red Valve's actuators are made from fiberglass-reinforced epoxy resin, offering exceptional resistance to corrosive chemicals, hydraulic fluids, water, and oil. The actuators operate in temperatures ranging from -90°F to 225°F and can withstand pressures up to 250 psi. The interior of the actuator is polished and impregnated with moly disulfide to reduce friction, while the piston seal uses a durable O-ring. A lip seal and rod wiper ring further protect the piston rod from dirt and wear.
WIVO Valves are also available with hydraulic or electric actuators, and can be customized with additional options like limit switches, solenoids, air regulators, and chainwheels.
